---------------------------------------------------------------------***--------------------------------------------------------------------Abstract- High rigidity and a high strength to weight ratio 1.1. CLASSIFICATION OF COMPOSITES are benefits of polymeric materials reinforced with synthetic fibers like glass, carbon, and aramid over traditional building materials like steel, concrete, and wood. Despite these benefits, synthetic fiber-reinforced polymer composites are becoming less and less common due to their high starting prices, inefficient structural forms, and—most importantly— disastrous environmental effects. On the other hand, one of the key reasons to investigate the possibility of employing natural fibers as reinforcement for polymers is the growing interest in using them as reinforcement in plastics to replace traditional synthetic fibers in several structural applications. Due of this, scientists have concentrated on studying natural fiber composites, also known as bio-composites, which are made of natural or synthetic resins and reinforced with natural fibers. Because renewable raw materials are healthy and do not harm the environment, researchers from all over the globe have been pursuing the production of highperformance engineered materials from renewable resources.
Composite materials are commonly classified at following two distinct levels

The main objective is to study and evaluate the mechanical and physical properties of polycarbonate granules as a reinforcement material in the epoxy resin matrix. A series of composite material will be developed by varying the weight% of polycarbonate granules that is 2%, 3%, 4% & 5%. And testing will be performed in order to analyze the mechanical properties of the developed material. The various tests include tensile test, impact test & bending test,
1. INTRODUCTION A composite is mixture of two materials in which one of the materials, known as the reinforforcing phase, is in the structure of fibers, sheets, or particles, and is embedded in the other materials known as the matrix phase. The reinforcing fabric and the matrix material can be meta l, ceramic, or polymer. Composites usually have a fiber or particle segment that is stiffer and more suitable than the continuous matrix segment and serve as the primary load carrying m embers. The matrix acts as a load switch medium between fibers.. The matrix is greater ductile than the fibers and thus acts as a source of composite toughness. The matrix additionally serves to guard the fibers from environmental damage before, for the duration of and after composite processing. When designed properly, the new mixed material reveals higher strength h than would each character material. Composites are used now not only for their structural properties, however additionally for electrical, thermal, tribological, and environmental applications.
