Abstract: Manufacturing of polymer matrix composites of different combinations of vinyl ester and polyurethane successfully carried. And also the heat distortion test is done. The heat distortion temperature for each specimen is found by using the heat distortion kit and the readings are tabulated and compared by graph. The proportion 40:60 and 20:80 does not formed as perfect IPN hence it is found that 80% vinyl ester and 20%polyurethane have good elasticity and toughness in comparison with other proportions.
