Composites in the world of today have wide range of applications, wherever high strength-to-weight ratio is important. Its principal uses are found in automotive, marine and construction industries. In majority of cases, there is requirement of high performance in the automotive and aerospace industries, the discontinuous phase or filler is in the form of a fiber. In most cases, composite matrices are the thermosets having carbon and ceramics for high temperature applications. Thermosets (epoxy, polysulfones) and thermoplastics (polyetherether ketone, polyimide) due to high strength and performance are pioneer for research and industrial applications. Nano-composites in the latest advances have high aspect ratio and improved electrical, mechanical and thermal properties that could be fabricated for various purposes.
The use of natural fiber as reinforcement in composite has been a challenging task. Fiber reinforced composite materials offered a combination of strength and modulus that are either comparable to or better than many traditional metallic materials. Increase in the flax and jute fiber content in polyurethane based composites increased the shear modulus and impact strength. However, increasing the micro void content in the matrix decreased its strength. The presence of bonding agent resulted in reducing curing time and improved mechanical properties. The use of maleic anhydride polypropylene as a coupling agent suppressed the moisture absorption and degradation in such composites. Thermosetting plastic composites reinforced with coconut fiber, agro-based materials such as banana, hemp, jute, flax and agave fiber using polymer matrix resins have also been reported. In the present scenario there is increase in the demand of fiber reinforced composite and there has been a lot of research in green composites. These composites are biodegradable and economic to procure. With the advancement of science and technology now there are various ways of characterizing composites by FTIR, SEM, TEM, AFM, TG-DTA, DSC, XRD are a few of them. Mechanical competence could be assessed by tensile strength, compressive strength, wear resistance, Young’s modulus, flexural strength, hardness etc. By the availability of new synthetic techniques and machines highly efficient composites could be obtained that are environment friendly, cheap and versatile for use in different applications. I look forward in high hopes that in coming year’s young scientist could explore better results and advancement in the field of composite could be seen.
