Polymers and Composites

Introduction:

 Polymers are an important category of materials replacing conventional materials in almost all fields of engineering applications. Being lightweight and with ease of processing, demand of polymers is increasing day by day. Also, new formulations and combinations are being explored to make further improvement in properties. Development of composites is also a dimension in which polymers have played a vital role. Combining metals, ceramics and polymers with other hard materials in the form of particulate, continuous and discontinuous fibers is a useful mean of enhancing properties of the matrices.
