    摘要： A welding method controls the welding temperature, welding cycle time, and welding pressure for fabrication of composite structural parts. A welding unit welds multiple plies (112) of thermoplastic prepreg into welded multi-ply assemblies (100) by concentrating welds along the thermoplastic prepreg plies at localized and strategic positions. Two platens weld a plurality of the multi-ply assemblies (100) into a layup (350) using a plurality of heated pins (360). The heated pins (360) are hollow to reduce surface heating during welding and are non-uniformly shaped to allow indexing of the layup (350). After the layup (350) is cut into a plurality of thermoplastic prepreg segments (510) along a layup pattern (500), the thermoplastic prepreg segments (510) are indexed according to the weld marks impressed by the non-uniformly shaped heated pins (360). The thermoplastic prepreg segments (510) are formed into kits (600) or wedges by stacking smaller thermoplastic prepreg segments (510) on top of larger thermoplastic prepreg segments (510).

    摘要： A compression mold apparatus (300) for compressing a segment (400) has a base (310) having an elongated and substantially semi-circular mold cavity (312) and an end plate including a blade (322) mounted thereon. The mold cavity (312) has a top opening. A ram (340) is aligned with the top opening. The ram (340) includes two fixed opposing planar flank surfaces (342). The two fixed opposing planar flank surfaces (342) are nominally centrally separated by a ram groove (344) for mating with the blade (322) while allowing linear movement within the mold cavity (312). A ram press (350) is connected to the ram (340) for translating the ram (340) linearly along the blade (322) within the mold cavity (312). A plurality of cartridge heaters (382) is mounted in the base (310) and arranged around the mold cavity (312) for heating the segment (400).
