Pultrusion is a process in which a continuous dry preform is pulled through a matched die while resin is injected under high pressure. It is first heated for cure and then cooled in the die to a temperature where it possesses sufficient strength to support the pulling clamp pressure. Once in operation, the process is almost labor free, yielding a product at just above the material cost (Goldsworthy, 1990). Die cost is reasonable if any volume is required. The most obvious restriction is that the part must be constant in cross section and laminate design. The quality of the laminate is excellent.
