ABSTRACT:
A method and an apparatus for forming elongated composite parts having constant cross sections. The apparatus comprises a form having a cross section, a portion of which is complementary to a first portion of the desired cross section of the elongated part. The apparatus further comprises a holding means having a cross section, a portion of which is complementary to a second portion of the desired cross section of the elongated part. Plies of preimpregnated composite material are held within a slip tape, which, in turn, is forced against the complementary cross section of the form by the holding means. The apparatus is then passed lengthwise along the slip tape enclosing the preimpregnated plies of composite material to cause the slip tape to tighten around the preimregnated plies and to generate a slip tape-enclosed, elongated part which is appropriately shaped to pass through a pultrusion die.
