Now-a-days, there is an increasing interest in hybrid composites made by combination of two or more different types of fiber in a common matrix because these materials offer a range of properties that cannot be attained with a single type of reinforcement. The fibres are either natural or synthetic and both types of fiber have advantages and disadvantages. Therefore, in this work a new class of hybrid composite reinforced with a synthetic fiber and a natural fiber is developed to get the advantage of both the fibres in terms of superior tribological properties and economy. The present research work is undertaken to investigate the erosion behaviour of short bamboo and glass fiber reinforced epoxy based hybrid composites.

Usage of Natural Fiber Composites (NFC) is increased rapidly due to the bio degradability nature of the fibers. These natural fibers are mixed with synthetic fibers to obtain better mechanical properties. In this study, pine apple and glass fiber reinforced epoxy composites are developed and their mechanical properties were evaluated. Composites were prepared by varying the fibers content and by using hand layup process with glass moulds of size 160 x 160 x 3 mm3 . The obtained laminates were sliced as per the ASTM criterion to test the properties. Higher glass fiber content in the composite specimen obtained higher mechanical properties. The composites can be utilized for the purpose of manufacturing components like doors panels, desks, roof tops etc.

The natural fiber-reinforced polymer composite is swiftly growing both in phrases of their industrial applications and fundamental research. They are renewable, cheap, absolutely or in part recyclable and biodegradable. The incorporation of herbal fibers consisting of sisal with glass fiber hybrid composites has additionally received growing industrial packages. Herbal and synthetic fibers are mixed in the same matrix (unsaturated polyester) to make sisal/glass fiber hybrid composites and the mechanical residences of those hybrid composites had been studied. A giant development in mechanical homes of sisal/glass fiber hybrid composites has been observed. the chalk powder (additive) is likewise introduced to the resin (unsaturated polyester) in proportions of 1%, 2%, 3% by way of weight of resin respectively and sisal/glass fiber hybrid composites were organized through the usage of this resin to take a look at the effect of chalk powder on mechanical homes of those hybrid composites. It is also found that because the chalk powder quantity increases tensile and flexural residences are decreases.

Natural Fiber Reinforced Composite (NFRC) are used by replacing Synthetic Fiber Reinforced Composites (SFRC) because of its poor reusability, recycling, bio degradability. Even though NFRC are lack in thermal stability, strength degradation, water absorption and poor impact properties. The hybridization and nanoparticles mixed in different polymers are used to improve mechanical and wear properties of the polymer composites. In the present investigation Multi wall carbon nanotubes (MWCNT) dispersed in Epoxy resin using ultrasonic bath sonicator are used as matrix face for hybrid banana-Glass Fiber Reinforced Plastics composite materials which is manufactured by compression molding processes. As per ASTM standards tensile, compression tests are carried out by using Universal Testing Machine. Microstructure of samples are investigated by scanning electron microscope (SEM) with Energy dispersive X-ray (EDS). SEM shows the homogeneous distribution of the fiber in the modified polymer matrix. The results indicated that the increase in weight % of MWCNT improves the mechanical properties of MWCNT filled hybrid natural fiber composites.

In recent years, natural fiber reinforced polymer composites have gained much attention over synthetic fiber composites because of their many advantages such as low-cost, light in weight, non-toxic, non-abrasive, and bio-degradable properties. Many researchers have found interest in using epoxy resin for composite fabrication over other thermosetting and thermoplastic polymers due to its dimensional stability and mechanical properties. In this research work, the mechanical and moisture properties of Caryota and sisal fiber-reinforced epoxy resin hybrid composites were investigated. The main objective of these studies is to develop hybrid composites and exploit their importance over single fiber composites. The Caryota and sisal fiber reinforced epoxy resin composites were fabricated by using the hand lay-up technique. A total of five different samples (40C/0S, 25C/15S, 20C/20S, 15C/25S, 0C/40S) were developed based on the rule of hybridization. The samples were allowed for testing to evaluate their mechanical, moisture properties and the morphology was studied by using the scanning electron microscope analysis. It was observed that hybrid composites have shown improved mechanical properties over the single fiber (Individual fiber) composites. The moisture studies stated that all the composites were responded to the water absorption but single fiber composites absorbed more moisture than hybrid composites.

The aim of this research work was to develop the optimal mechanical properties, namely, tensile strength, flexural strength, and impact strength of sisal and glass fiber-reinforced polymer hybrid composites. The sisal, in the form of short fiber, is randomly used as reinforcements for composite materials, which is rich in cellulose, economical, and easily available as well as glass fibers have low cost and have good mechanical properties. In addition, epoxy resin and hardener were for the fabrication of composites by compression molding. The selected materials are fabricated by compression molding in various concentrations on volume basics. The combination of material compositions is obtained from the design of experiments and optimum parameters determined by the Response Surface Methodology (RSM). From the investigation of mechanical properties, the sisal is the most significant factor and verified by ANOVA techniques. The multiobjective optimal levels of factors are obtained by LINGO analysis.

Automobile bumper is an essential component that is commonly used to absorb the impact load during vehicle collisions, in fact it saves lives at such occurrences.In order to withstand the impact load, and the bumper deforms itself during collision and protects the passengers by havingthe proper cross section and the material selection. In this way, the study explores the mechanical characterization of fabricated composite and its structural analysis. Impact conditions have to be studied for improving the mechanical properties of the bumper during collision. The material chosen for analysis is jute and Glass fiber reinforced hybrid epoxy composite, considering its light weight and strength characteristics. Composites with two different fibre orientations (45°/90°) are fabricated using Hydraulic Compression Moulding technique. From experimental observations of jute and glass fiber reinforced hybrid composites, the orientation has significant effect on the structural and mechanical properties. The results are validated using the simulation of a bumper by impact modelling using CATIA software and impact analysis is carried out using ANSYS.

The fibers from naturally available resources are considered to have potential alternate reinforcing agent in polymer matrix composite materials due to their properties such as high strength, stiffness, degradable in nature and renewable in nature. In this study a lightweight, low cost and environment friendly hybrid composites are prepared by using sisal-jute-glass fibers as the reinforcement materials. There are three types of composites such as sisal/glass fiber reinforced polymer (SGFRP) composites, jute/glass fiber reinforced polymer (JGFRP) composites and sisal/jute/glass fiber reinforced polymer (SJGFRP) composites are prepared by hand lay-up process and underwent to charpy impact test in order to study their impact properties. Post impact induced damage, material failure mechanism, matrix cracking, fiber breakage and pullout was observed by using scanning electron microscopy (SEM) analysis. The results showed that the energy absorption and load carrying capacity of JGFRP composites are better and able to withstand higher loads than SGFRP composites and SJGFRP composites. It is further observed from the experiment, the inclusion of sisal and jute fibers with glass fiber reinforced polymer (GFRP) composites has gained good impact properties. It is suggested that these light weight sisal and jute fibers have been used as an alternative reinforcing material to synthetic fiber for medium load applications.
