Beschreibung
Zusammenfassung:	A method and apparatus is provided for forming elongated composite structural members (702) with a desired cross-sectional geometry as taken transverse to the length of the member. An apparatus may include a base with a substantially elongated mandrel (706) mounted thereon. One or more rollers (728) configured to at least partially complementarily engage the mandrel are configure to roll over and press one or more plies of composite material onto the mandrel. The mandrel may be disposed on a rotary table (716) and configured to exhibit a curved elongated geometry to form at least partially curved or arcuate elongated members. The present invention enables the formation of elongated structural members from resin impregnated materials while maintaining the materials in a substantially uncured state. The formed members may then be cocured with a skin or other composite structure.
