Abstract:
1. A method of forming an elongated composite structural member, the method comprising: providing a substantially elongated mandrel having an exterior surface exhibiting a desired cross-sectional geometry; laying up at least one ply of fiber material preimpregnated with a thermosetting resin on the mandrel; and pressing and forming the at least one ply onto the mandrel with a plurality of rollers that are sequentially passed along a length of the mandrel to sequentially press and form the at least one ply on the mandrel, each of the rollers being at least partially complementary in shape with the cross-sectional geometry of the mandrel while maintaining the at least one ply in a substantially uncured state during the pressing and forming, at least one of the rollers that presses and forms the at least one ply onto the mandrel having a ply engaging portion width that is less than a width of the at least one ply.
