Abstract

The main aim of this study is to investigate the Impact properties of Epoxy matrix composites by a drop weight impact tester using spherical steel projectile with five different ranges of heights. Three different types of reinforcement were used in the experimental works: woven glass, woven glass+carbon, unidirectional carbon. This study showed that reinforcing epoxy with unidirectional and woven carbon and glass improves the impact properties. Minimum deformation and maximum force and energy were in woven glass reinforced epoxy, while unidirectional carbon reinforcement showed low impact energy absorption and high deformation and failure in a very short time compared with others due to susceptibility to impact damage while the impact strength of hybrid carbon+glass is higher than carbon composites because glass fibers add additional resistance to impact and damage.

Keywords:

Drop weight impact, epoxy resin, unidirectional fiber and woven fiber,
