ABSTRACT:
A resin matrix (70) is formed and reinforcement fibers (72) and thermoplastic material (74) are added to the resin matrix (72). The resin matrix (70), the reinforcement fibers (72) and the thermoplastic material are moved through a pultrusion die (76), by pulling on the reinforcement fibers (72), to form a conveyor slat having a top portion (38) and a pair of laterally spaced apart side portions (40, 42) depending from the top portion (38). In the pultrusion die (76) heat is applied to melt the thermoplastic material (74) and cause it to migrate to an outer surface portion of the slat body. A veil (90) of thermoplastic material may be bonded to the surface layer of thermoplastic material.
