This research tends to study the effect of the two types of carbon fiber; wet and dry; on hardness, and impact strength of polystyrene (PS) matrix composite. Specimen were prepared as laminate containing (2) layers of (PS) and (2,4,6,8,10) layers of wet and dry carbon fibers separately. Brinell hardness, and Charpy impact has been measured for the specimen, it has been found that (PS) reinforced with dry carbon fiber is much lighter and harder, and more resistance to impact.
Key words:- Laminate composite, Carbon Fibers, Polymer matrix composite.
