Pultrusion Defined

During the pultrusion process a continuous fiber reinforcement in roving or mat/roving form is drawn through a resin bath to coat each fiber with a specially formulated resin mixture. The coated fibers are assembled by a forming guide and then drawn through a heated die. Resin is cured by heat in the die and a catalyst in the resin. The resulting high-strength profile is cut to length, ready for use. The process can be visualized simply as extrusion, but with pulling of raw materials through the die rather than pushing them.

A pultruded composite consists of reinforcing material, a laminating resin that binds the composite together, possibly a surfacing veil to improve the external appearance of the composite, and chemical resistance and/or weather resistance, if necessary. A variety of ancillary materials may be added, such as pigment for color, accelerators to speed the curing of the laminating resin, internal release agents, inert fillers, etc.
