The effect of the manufacturing procedure on the electric properties of carbon-black-filled,fiberglass-reinforced thermoplastic composites

The electric properties of carbon-black-filled, fiberglass reinforced thermoplastic composites with unidirectional and random structure were studied. Their samples were prepared according to various manufacturing processes: injection molding, molding, press molding, winding, and pultrusion. It was shown that the electric properties of the composites are determined by the character of distribution of filler particles in the polymer matrix, which is closely related to the blending parameters and the engineering properties of the material.
