Composites based on polyamide 6 matrix and carbon fiber with the diffirent mass ratio were investigated to evaluate their mechanical properties. Polyamide 6 made by BASF was used as the matrix with chopped carbon fiber made by two different firms Gungwei (china) and Toray (japan) as the reinforcements for fabrication of composites. Tensile strength at break, flexural strength, hardness and izod impact were measured to compare properties of composites based on pa6 matrix with two different reinforcements of chopped carbon fiber. The morphology of bonding beetween pa6 and chopped carbon fibers was studied by SEM methods. The results showed that with the mass ratio 70/30 tensile strength at break, flexural strength, hardness and izod impact of composite based on pa6 matrix and chopped carbon fiber made by Toray reach the highest value in the survey range 67.4 MPa, 104.3 MPa, 37.6 HRC and 67.1 J/m respectively. Bonding morphology beetween pa6 and chopped carbon fiber with the mass ratio 70/30 showed that pa6 is more compatible with carbon fiber made by Toray than carbon fiber made by Gungwei.
