Al2O3 and graphene (1% by mass) and their mixts. were added sep. to powdered polyamide and then heated at 180 degrees C under load 60 kN. Modulus of elasticity, microhardness, elastic, non-elastic and total work deformation of the composites as well as of polyamide matrix were detd. by using depth indentation method. The composite with graphene showed the best mech. properties.
