In the present work we investigated some properties of polypropylene composite material at processing temperature was varied from 170 °C to 200 °C for processing time ranged from 6 to 9 min, polyamide fiber and carbon black powder was blended with polypropylene with different weight ratios as a composite material model. The composite sheet of 150 mm length, 100 mm wide and 2 mm thickness are produce as a model using Hydraulic melt Press techniques. The obtained sheet was characterized by, melt flow index and water absorption, Thermogravimetric analysis was used to characterize the produced sheets interims of thermal stability and thermal degradation. The obtained results showed that the MFI decreased when both carbon black and polyamide fiber was introduced to polypropylene. percentage of water absorption increase with increase of the polyamide content. The thermal stability of polypropylene decreased when polyamide fiber and carbon black powder were added.
