Polymer and their composites are used in many engineering applications as an alternate of metals, because of the parameters such as low cost, light weight and durability. Hybridization is a process of mixing two or more similar or dissimilar materials. It increases the performance and efficiency. In this study investigation has been made on mechanical properties of HDPE polymer based hybrid composites fabricated from the effect of various synthetic fibers (SGF ,PTFE,SCF), synthetic fillers(Silica, hydroxyapatite, zirconia) by melt mixing method using twin screw extruder followed by injection molding technique. The mechanical properties of the samples such as tensile test, flexural test were measured by universal testing machine. And the impact test was performed on Izod impact testing machine. The results show that the tensile strength of hybrid composite TR-4 sample increases compared to other composites. Flexural strength of sample TR-6 shows highest flexural strength comparted to others. The impact strength increases when the filler materials 2% of zirconia and 2% of hydroxyapatite are added to composite material i.e. is TR-6 sample.

It is clearly observed that the mechanical properties were increased with the addition of weight percentage of woven Kevlar in the kenaf composites. The highest energy was recorded at by hybrid composite in combination of 20 wt% Kevlar. The structure observation of impacted hybrid samples showed that as the impact energy increased, the energy absorbed was also increased. It is found that reinforcing kenaf fibre composite with woven Kevlar can improve mechanical properties of kenaf fibre.

Over the last decades composite materials, plastics and ceramics have been the dominant emerging materials. The volume and number of applications of composite materials have grown steadily, penetrating and conquering new markets relentlessly. So everybody is concentrating on new materials which will be strong enough, less weight, recyclable with reduced cost. Hence all the researchers are concentrated on the composite materials which have all the above properties. The present work is concentrated on coconut coir fiber and Rice husk reinforced polyester hybrid composites. The composites specimen was fabricated with various weight percentages of natural fibers namely coconut coir (20%, 15%, 10%, and 5%) and Rice husk (15%, 10%, and 5%) combined with CamElect 3321 resin using hand lay-up method. So to obtain new composite materials different proportions of coconut coir and Rice husk is added and the mechanical properties such as Tensile strength, Flexural Strength and Impact test were carried out for the samples cut from the fabricated composites specimen to the dimensions as per ASTM standard. With the increasing percentage of the reinforcements the performance of the material is improving. The tensile strength increases with the increase in coir reinforcement percentage and flexural strength increases with the increasing in percentage of the rice husk and the impact strength of the material gets boost with equal proportional percentage of coconut coir and rice husk reinforcement.

GF reinforced polymer composites to improve the mechanical properties by increasing fiber content, but there is a limit. On the contrary, CF reinforced polymer composites are superior to the GF composites at a lower CF content in tensile and bending properties. However, CF is more expensive than GF. In this study, acrylonitrile butadiene styrene (ABS) was reinforced with single and hybrid reinforcing of glass fibers (GF) and carbon fibers (CF). The composites consisting of GF/ABS, CF/ABS and GF/CF/ABS were fabricated by direct fiber feeding injection molding (DFFIM). The reinforcing fiber was directly fed at the vent hole of the barrel in the DFFIM process. The effects of fiber Tex, fiber numbers and processing parameters on properties of the composites were investigated. Tensile, bending and Izod impact testing was conducted to compare mechanical properties of GF/ABS composites, CF/ABS composites and hybrid GF/CF/ABS composites. Morphology of the composites was observed by scanning electron microscopy. In addition, the cost advantage of each composite was compared with their mechanical properties. From the results, the addition of carbon fiber improved tensile, bending and impact properties of the hybrid composites. SEM photographs indicated that carbon fiber tended to agglomerate during the DFFIM process. The hybrid GF/CF/ABS composites presented an equivalent improvement in tensile and bending properties as compared to the CF/ABS composites. It can be noted that the low CF content was suitable for enhanced mechanical performances of the hybrid GF/CF/ABS composites. Therefore, the hybrid composites can be manufactured at a low cost as compared to the similar mechanical properties of the CF/ABS composites.

In this work, epoxidized natural rubber (ENR) is used to improve the impact strength of poly (methyl methacrylate) (PMMA). The natural rubber with poly (3-trimethoxysilyl propyl methacrylate) core-shell (adNR), prepared by admicellar polymerization, is used as the compatibilizer for PMMA/ENR blends which were prepared through melt mixing in a twin screw extruder. The effects of ENR and adNR contents on impact property were investigated by pendulum impact tester. The impact strength increased with ENR and adNR contents. The morphology on the fracture surfaces were demonstrated by using field emission electron microscope (FE-SEM), which showed the compatibility between ENR, adNR and PMMA. Furthermore, the effects of ENR and adNR contents on dynamic and mechanical properties were examined by dynamic mechanical analyzer and universal testing machine, respectively. The results illustrated that the incorporation of the adNR affected the dynamic and mechanical properties of the blends.

Short carbon fibre (CF) and sawdust (SD) were dispersed in to the epoxy (EP) matrix in order to manufacture polymer hybrid composites using compression moulding technique. The mechanical properties of flexural properties of hybrid, compression moulded, chopped CF/SD/epoxy composites have been investigated taking into account the effect of hybridization by these two fillers. Hybridization with small amounts of SD makes these CF composites more suitable for technical applications. The simultaneous compounding of epoxy with two fillers was done to obtain a hybrid composite. This system is expected to have considerable mechanical properties, good surface finish and low cost. It has been found that the tensile properties of filled epoxy were higher than unfilled epoxy. By incorporating up to 30% (by mass) Carbon fiber (CF) and 10% sawdust (SD) namely S3 sample flexural strength was increased by 12.5%. Thus it is shown that the durability of CF/SD filled epoxy composites can be enhanced by hybridization with small amount of CF. The hybrid effects of the flexural strength and modulus were studied by the rule of hybrid mixture.

Having wide range of applications due to its light weight, high strength and low cost. These composite materials are now being explored in applications of aerospace and automotive industries. In the present work, the composite material is prepared with intermediate aramid fabric layer (Kevlar) which is high strength fiber and it is combined with jute fabric reinforced epoxy composite to increase the strength of kevlar. This composite material is tested for mechanical properties like flexural, tensile & impact strength are calculated with UTM (universal testing machine) for flexural, tensile tests and impact testing is done with impact testing machine. Through this test results the impact strength of the composite material is calculated. The energy dissipation by impact test of jute and kevlar fabric composite and strength of fibers will be analyzed by scanning electron microscopy (FESEM). Thermo gravity analysis (TGA) and differential thermal analysis (DTA) is carried out. Through these test results it can conclude that the jute can be combined with the kevlar where the impact is primary considerations like bulletproof vests, automobile bodies, tyres etc. The usage of jute in all kevlar applications will increase the strength of kevlar by reducing the usage of Kevlar and cost will be minimized.

Abstract Abrasive tools consist of abrasive grains, binder and pores. Binders are the matrix of the material and may be of the metallic, vitrified or resin type. The wide use of polymeric materials (resinoid) is due to their low cost and excellent mechanical properties. The grain has the function of roughing the material, the binder, on the other hand, has the characteristics of ensuring grain adhesion and the pores in the structure are responsible for cooling the abrasive tool. In this work, we report the preparation and evaluation of the mechanical characteristics of resin bond composite abrasives with different structures based on the porous concentration. The composite abrasives were made with phenolic resin and alumina grains. Four different structures were studied from 10 to 30% of porous volume fraction with 50% of grain volume fraction. The concentration of porous and bond in the structure composition were employed to compare the mechanical performance of the prepared composite abrasive. To evaluate the mechanical properties of composites, Impact strength, Young’s Modulus by impulse excitation and flexural strength were realized. It was observed that as the porosity is higher, the impact resistance (absorbed energy) is lower, which confirms the lower resistance produced by the surface area contact (grain/binder) and a greater accumulation of tension in the binder material, the higher porosity value, higher the flexural strength value until 20% of porosity. Samples with higher volumes level of porosity presented lower Young’s Modulus but the presence of pores produced by volatiles by-products (mainly water) should act as stress concentrators, thus favoring lower mechanical properties at the resin-grain interface.
