Abstract
The effect of particle fraction on mechanical properties of particlereinforced composites was studied using tensile and hardness testing Unsaturated polyester UP was used as polymer matrix and aluminum hydroxide as the reinforcing particles The fracture morphology of tensile samples was observed by scanning electron microscopy SEM The results showed that the tensile strength and absorbed energy increased to a maximum at 10 particle content and then decreased With increasing content of aluminum hydroxide the elastic modulus increased and the fracture elongation decreased The SEM showed that the failure of the AlOH3/UP composites was one of macroscopically brittle fracture In addition the study showed that appropriate amount of filler can enhance the surface hardness of AlOH3/UP composite
