The ever increasing demand for new materials that have a high degree of structural stability combined with a high degree of strength has focused attention on the possibility of manufacturing composites by unorthodox routes. Composites have extended the horizon of engineering materials beyond the realm of natural combinations to man-made combinations. Polymers are particularly attractive as matrix materials because of their relatively easy processability, low density, and excellent mechanical and dielectric properties. ...

The ever increasing demand for new materials that have a high degree of structural stability combined with a high degree of strength has focused attention on the possibility of manufacturing composites by unorthodox routes. Composites have extended the horizon of engineering materials beyond the realm of natural combinations to man-made combinations. Polymers are particularly attractive as matrix materials because of their relatively easy processability, low density, and excellent mechanical and dielectric properties. Polymer matrix reinforced composites are most commonly used in structural applications such as aircrafts, boats, automobiles etc. The main objective of this research work is to develop a new polymer based composite material. In the present study, the researcher has identified and selected a two-component polyurethane vacuum casting system used for rapid prototyping - Ureol 5236 TM. Part in minutes-vacuum grade polyurethanes procured from Ciba Specialty Chemicals Ltd, Bombay. This resin is used to produce functional prototype parts suitable for use in all major industrial areas including automotive, aerospace, consumer goods and leisure applications.
