Pultrusion is a fiber-reinforced plastic composites forming process whereby continuous fiber reinforcement (filament, roving or woven fabric) is pulled through a bath to saturate the fiber reinforcement with a specially formulated resin mixture. The resin impregnated tow is drawn through a forming guide and heated die for removal of excess resin. The remaining resin is cured to form a rigid, infusible fiber-reinforced polymer composite. The resulting high-strength, profiled shape is automatically cut to length for use in advanced engineering structural applications. The AAPPI maintains a Martin Pultrusion Durapul 1204 pultruder for the production of advanced structural composites.
