In this project, two different types of resin as matrix and glass fibers in form of scrap, woven and felt as supplementary material were used in manufacturing plastic matrix composite material supplemented with fiber being used in tractor hood manufacturing. Fiber type and ratio was kept constant in the resulted samples and their situations were examined after they hardened at room temperature. The materials hardened at room temperature and one group was not cured and the other was exposed to post-curing process and then, they were tested on Q 800 TA Dynamic Mechanical Analyzer instrument. HDT values were determined according to ASTM E 2092-04 stand while Tg values were determined according to ASTM E 1640-04 stand. The results were reported after they were interpreted.
