  The pultrusion process starts with racks or creels holding rolls of fiber mat or doffs of fiber roving. Most often the reinforcement is fiberglass, but it can be carbon, aramid, or a mixture. This raw fiber is pulled off the racks and guided through a resin bath or resin impregnation system, resin can also be injected directly into the die in some pultrusion systems.

  The raw resin is almost always a thermosetting resin, and is sometimes combined with fillers, catalysts, and pigments. The fiber reinforcement becomes fully impregnated (wetted-out) with the resin so that all the fiber filaments are thoroughly saturated with the resin mixture.
