Pultrusion is a continuous process of manufacturing of composite materials with constant cross-section whereby reinforcing fibers are pulled through a resin, possibly followed by a separate preforming system, and into a heated die, where the resin undergoes polymerization. Many resin types may be used in pultrusion including polyester, polyurethane, vinylester and epoxy.
Additional recommended knowledge
The design of pultrusion machines varies. Two often used types are reciprocating (hand-over-hand) and continuous (cat-track).
The term is a portmanteau word: "pull" & "extrusion".
The first pultrusion patent in the United States was issued in 1951. W. Brandt Goldsworthy is widely regarded as the inventor of pultrusion.
