Vespel CP-0301 composite parts from sheet molding compound consist of long, chopped fibers held in a polymer matrix. The discontinuous nature of the fibers allows the fibers to align with the contours of the part, permitting the molding of relatively complex shapes, while providing reinforcing strength. Vespel CP-0301 parts demonstrate high strength and low weight for aircraft clamps and similar components
