An integrated approach of quality for polymer composite manufacturing validated and optimized through Taguchi method

An integrated approach of quality for polymer composite manufacturing validated and optimized through Taguchi method

Desired product quality is required to be embedded right from the design stage. As an initial step, product and process specications are dened and design at- tributes are estimated. Selection of appropriate mate- rials, such as ber type, matrix, and core, are nalized based on required technical characteristics. Subse- quently, peculiar settings of process control parameters are ensured, and the product is produced as per laid down criteria. The product quality is then measured through a series of non-destructive and destructive testing procedures to validate the desired quality char- acteristics. For the purpose of this study, thirteen key variables from various stages of manufacturing, including design, material, and process control param- eters, were selected to test the proposed framework. Weight and thickness were selected from design stage. Fiber type, matrix, and core type were chosen from the material. Resin hardening mixing time, viscosity, layup pattern, tooling, cure type, temperature, labour type and process technique were selected from the process control parameters. Accordingly, polymer composite sandwich laminates were produced by varying the values of these variables. Samples were tested through destructive testing technique (three-point bending),

The Unique, Centrifugally Cast, Fiberglass-Reinforced, Polymer Mortar Pipe

Connections to Other Pipe Material Systems Connections to other pipe material systems may be accomplished by several methods. Because of compatible OD’s, HOBAS pipes, 18” to 48”, may be joined directly with ductile iron pipes using either our couplings or ductile iron gasketed joints. In some diameters and applications, Fernco couplings may be suitable. Additionally, HOBAS Pipe USA can frequently custom fabricate the mating bell or spigot for other gasket-sealed systems when the proper dimensions are known. Further, custom fabricated mechanical couplings capable of connecting pipes of different OD’s maybe utilized. Although typically the most expensive method, flanges built to ANSI or other drilling specs may also be used. Contact us regarding suitability of or experience with other procedures.

Analysis of Delamination in Carbon Fibre Reinforced Polymer Composite using Finite Element Method

Analysis of Delamination in Carbon Fibre Reinforced Polymer Composite using Finite Element Method

ABSTRACT: Composite laminates such as carbon fibre reinforced polymer (CFRP), glass fibre reinforced polymer (GFRP) and fibre metal composite laminates (FMLs) are being widely used in aerospace and automotive industry. The demand for these materials is increasing due to their superior properties such as high strength to weight ratio, good corrosion resistance and high stiffness. Drilling is a major process in manufacturing of holes which is required for assembling the components in industry. Drilling of holes in CFRP leads to a drilling induced damage called delamination. The researchers have tried to reduce the drilling induced damage by minimizing the operating variables and tool design. However the research on delamination analysis using finite element method is limited. This research paper includes the designing of drill bit using 3D modeling software CATIA V5.0 and the composite material is modeled using finite element analysis (FEA) software ANSYS V14.5. Analysis is carried out for various spindle speed, point angle and feed rate.

Use of Polymer Composite in Bridge Rehabilitation

Use of Polymer Composite in Bridge Rehabilitation

Spray-up process is similar to hand lay-up process, but much faster and less expensive. In this process, a spray gun is used to apply resin and chopped reinforcements to the mould. Glass fibres chopped to a length of 10 to 40 mm are usually used as reinforcement. It is more suitable for manufacturing non-structural parts that do not require high strength. However, it is very difficult to control the fiber volume fraction and thickness, and it is very dependent on highly skilled operator. Therefore, this process is not appropriate for parts that require dimensional accuracy. One of the semi-automated processes is resin infusion under flexible tooling process. This method is mainly used to retrofit CFRP to steel, cast iron, and concrete bridges. In this method, fibres are performed in a mould and transported to site. The preform is then attached to structure being retrofitted and enveloped by vacuum bagging system, together with a resin supply. Resin is then injected into the preform, forming both composite material and adhesive bond between the composite and the structure. This process yields high fiber volume fraction as high as 55%.

EXPERIMENTAL INVESTIGATION OF CO2 LASER CUTTING OF COMPOSITE MATERIAL (CFRP- CARBON FIBER REINFORCED POLYMER): A REVIEW

EXPERIMENTAL INVESTIGATION OF CO2 LASER CUTTING OF COMPOSITE MATERIAL (CFRP- CARBON FIBER REINFORCED POLYMER): A REVIEW

Promoting the massive use of carbon-based plastic (CFRP) in the industry can be achieved through faster and more flexible technologies such as laser cutting. The anisotropic and heterogeneous properties of CFRP are a major challenge for laser processing. We present an exhaustive study on laser cutting performance composed of CFRP (3 mm thick). The high emission CO2 laser is used to familiarize with the capabilities of CO2 laser cutting machines widely used in metal machining applications for the machining of this material. On the other hand, the effect of the processing parameters has been studied in both CW and pulse mode. The minimum areas affected by heat, approx. At a depth of 540 lm, a high pressure CO2 laser was used in pulse mode. As a result, the strength of the CFRP does not change in practice compared to more conventional mechanical machining.

Alternative design of pipe sleeve for liquid removal mechanism in mortar slab layer

Figure 6 shows the volume of water collected in six hours for every design pipe sleeve. For pipe sleeve E, it shows that the volume of water that flow out was increased rapidly in six hours in time. While for pipe sleeve D, the volume of water collected was a bit slow for the first hour as it remains at zero value and then for the next hour, it was gradually increased for the next five hours. For C, the volume of water flow out was increased slowly but in constant mode for the six hours. Lastly, the volume of water collected for B, A and Conventional pipe sleeve were in the same state which was constantly in zero as there is no water collected for the six hours period of time. Pipe sleeve E shows the highest volume of water flow out in the period of six hours because it covers more surface area percentage resulting the higher number of holes to flow out the water from the mortar.

Rheology Effects on Predicted Fiber Orientation and Elastic Properties in Large Scale Polymer Composite Additive Manufacturing

Rheology Effects on Predicted Fiber Orientation and Elastic Properties in Large Scale Polymer Composite Additive Manufacturing

Fiber orientation studies in polymer composite AM applications have recently become of interest. Nixon et al. [11] simulated fiber orientation in three Fused Deposition Modeling (FDM) nozzle geometries (convergent, straight and divergent) using Moldflow (Moldflow Corporation, Framingham, MA, USA) and the Folgar–Tucker Isotropic Rotary Diffusion (IRD) model [12]. Their work, which ignored die swell, showed that a converging geometry yielded the highest principal fiber alignment and the divergent geometry resulted in the lowest. Additionally, at the exit of the straight and the converging nozzle, a higher alignment was predicted near the center than at the edge, unlike the experimental result reported by Kunc [13]. Heller et al. [14] computed the fiber orientation tensors in a conventional small scale FDM nozzle and extruded filament. In their work, die swell was computed by minimizing the integrated normal stress on the free surface using COMSOL Multiphysics (Comsol, Inc., Burlington, MA, USA). Their approach modeled the molten polymer as an isothermal Newtonian fluid in a creeping flow, and assumed an axisymmetric velocity field. Orientation tensors (c.f. e.g., Advani and Tucker [15]) were computed along streamlines within the flow domain from velocity and velocity gradient information. Their results showed that fiber alignment reached its peak at the outer edge of the nozzle, and then decreased towards the center of the flow.

Preparation and Electrochemical Performance of Polymer-derived SiCN-graphite Composite as Anode Material for Lithium Ion Batteries

Preparation and Electrochemical Performance of Polymer-derived SiCN-graphite Composite as Anode Material for Lithium Ion Batteries

the SiCN particles are acetylene black and PTFE which respectively act as conductive additive and binder in the preparation process of the material. However, they are not completely filled in all the interfaces of SiCN particles, forming many voids and cracks among SiCN particles. This results a bad electron transfer. Nevertheless, as shown in fig. 4b, the SiCN-graphite composite has no distinct crack, in favor of electron transfer. The particle sizes are larger than 3-5 μm, which bigger than the pure SiCN material which is benefited to the resistance of capacity decay during cycling.

Polymer composite based microbolometers

The aim of this work was the basic suitability assessment of polymeric materials and related technological methods for the production of polymeric materials for the manufacture of microbolometer arrays with a sensitive layer of electri- cally conductive polymer composites. The all-polymer com- patible technology chain is an innovative approach to the manufacture of polymer-based, self-supporting MEMS (mi- croelectromechanical systems) structures and allows for a prospective economization potential as well as highly par- allel processing suitability. Concerning their suitability for use as sensitive layers in a microbolometer pixel, additional metrological and physical observations were made regarding the electrical properties of polymer composites filled with either tellurium needles, vanadium dioxide particles or silver particles.

Fiber Reinforced Polymer Composite

Fiber Reinforced Polymer Composite

Fiber reinforced polymer (FRP) is a composite material made by combining two or more materials to give a new combination of Properties. However, FRP is different from other composites in that its constituent materials are different at the molecular level and are mechanically separable [1]. The mechanical and physical properties of FRP are controlled by its constituent properties and by structural configurations at micro level. Therefore, the design and analysis of any FRP structural member requires a good knowledge of the material properties, which are dependent on the manufacturing process and the properties of constituent materials.FRP composite is a two phased material, hence its anisotropic properties. It is composed of fiber and matrix, which are bonded at interface. Each of these different phases has to perform its required function based on mechanical properties, so that the composite system performs satisfactorily as a whole. In this case, the reinforcing fiber provides FRP composite with strength and stiffness, while the matrix gives rigidity and environmental protection. Fiber is a material made into a long filament.

An Experimental Investigation Report of Chloride and Sulphate effects on geo polymer mortar

As per recent researches conducted GPM reduces the cost of binding material as compared to standard cement. The compressive strength test was performed and an empirical formula was derived from the results. Vijaysankar et al (2013) have investigated the behaviour of fly ash based geopolymer mortor solid blocks and its durability. The cubes were cast with fly ash to river sand with the ratio of 1:3. by weight. Mortor cubes of size 70.6 x 70.6 x 70.6 mm were prepared and cured under oven curing for 24 hours. The compressive strength was found out at 7 days and 28 days. The results are compared. The optimum mix is Fly ash: Fine aggregate (1:3) with a solution (NaOH and Na2SiO3 combined together) to fly ash ratio of 0.35. The results conclude that high and early strength was obtained in the geopolymer concrete mix and geopolymer concrete was a workable mix

A Review on Natural Fibre Polymer Composite

A Review on Natural Fibre Polymer Composite

5. Tribiology properties of NFPCs: All the materials are having some friction and wear properties that get damage or degrade with time. Thus the tribiological properties should be considered necessary for improving mechanical part design. As their difference cause much failure in composites. The tribiological properties can be altered positively or negatively by the reinforcement method. For example the kenaf fibre which are reinforced with epoxy composites showed 85% improvement in wear performance when used for bearing applications. Also the natural fibres such as nettle, grewia, optiva and sisal are used to make laminated composites by hot compression method and then the wear and friction properties are analysed. The results showed an approx reduction of 10-44% in coefficient of friction. 6. Viscoelastic behaviour of NFPCs: The viscoelastic behaviour of natural fibre polymer composites determines the interface characteristics and important insight into the structure morphology over a range of temperature. The maximum energy that is stored in the material in single cycle of oscillation is measure by storage modulus which gives information about the stiffness behaviour and load bearing capacity. The ratio of loss modulus to the storage modulus is called the mechanical damping coefficient.

Studies on Hybrid Composite Material

Studies on Hybrid Composite Material

Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation. The Brinell hardness test method as used to determine Brinell hardness, is defined inASTM E10. . Brinell testing often use a very high test load (3000 kgf) and a 10mm wide indenter so that the resulting indentation averages out most surface and sub-surface inconsistencies.

Design of Composite Material Flywheel

Design of Composite Material Flywheel

Flywheel is mechanical device which is used to store the kinetic energy. It stores up energy when the demand for energy is less than the availability and delivers energy when there is a lean period (when demand is more). So the main aim of project is to store more energy or same energy as that of conventional means. It is achieved by two ways either change the dimensions or use different materials. As the flywheel used in punching press or other machine is so bulky. Instead of changing the dimensions we change the materials and use such materials which store same energy with reduce mass of flywheel. Materials used for flywheel depend on the application, some of they are cast iron, grey cast iron, mild steel etc. Flywheel are manufacturing by casting process with single materials with high strength but more weight. In order to get high strength and reduce weight, we go for composite materials for flywheel. In this report we are design the flywheel, develop and optimize the mass of flywheel using composite materials like carbon fiber with cast iron.

Environmental Effect On Composite Material

Environmental Effect On Composite Material

In thinking about planes, it is worth remembering that composites are less likely than metals (such as aluminum) to break up completely under stress. A small crack in a piece of metal can spread very rapidly with very serious consequences (especially in the case of aircraft). The right composites also stand up well to heat and corrosion. This makes them ideal for use in products that are exposed to extreme environments such as boats, chemical-handling equipment and spacecraft. In general, composite materials are very durable. Another advantage of composite materials is that they provide design flexibility. Composites can be molded into complex shapes – a great asset when producing something like a surfboard or a boat hull.

Drilling Of Aero Composite Material

Drilling Of Aero Composite Material

Drilling process of aero composites material is the most critical procedure in the whole aspect of its manufacturing process. Any defects that lead to the rejection of the parts represent an expensive loss. In the aircraft industry, drilling associated delamination accounts for 60% of all part rejections during final assembly of an aircraft. The part must be rejects even for the slightest defect because it can risk the life of countless passengers on the aircraft. The composites performances are reduced due to the bad quality of the drilled holes. The hole machining defects have significantly reduced the strength and fatigue life of carbon/epoxy laminates.
