Abstract	The effect of the type of reinforcement was studied using Charpy impact test as well as hardness test. The material used is composed of polyester reinforced with fiber glass; a material increasingly and widely used in plenty of engineering applications, recently. In order to maximize the output of the present work, studies were carried out on different weight fraction of reinforcement. Two types of composite reinforcement were tested, namely the use of chopped fibers (randomly distributed glass fibers) and woven roving (laying fibers normal to the randomly distributed ones). It has been noted that the values of the Charpy impact resistance and hardness of the tested specimens, yield increases for weight fractions of reinforcement of about 30% to 40%. The results show that there is a scatter in the values of Charpy impact resistance and hardness in the ranges of weight fraction below and higher than the 30% to 40% range. It is also observed that the values of Charpy impact resistance and hardness of the chopped composites are higher than those of chopped and woven roven ones due to the fiber distribution and orientation. The direction of the load is at random angles of orientation to the Chopped fibers in the case of Chopped fibers. The paper discusses the results to explain the out coming trends.
