-This work aimed at the investigation of the effects of the addition of a short polyamide fiber and carbon black powder on the impact strength and the surface hardness of polypropylene composite. The composite sheets were produced by using compression mould technique at different processing temperatures and times. The weight percentage of both polyamide fiber and carbon black in the composite were varied. The obtained results illustrated that processing temperature and time had insignificant effects on the surface hardness. The optimum fiber and carbon black contents under the experimental conditions were 9.22% and 0.245%, respectively. Processing temperature, fiber content and carbon black content had a reverse effect on the impact strength of the composite while the maximum value of the impact strength of 23.63 Kj.m-2 was recorded when the composite heated up to 7 min.
