摘要： Stiffener tool positioning apparatus (1000) and method are provided. In one embodiment, the apparatus includes a base (1002), a first flipper member (1016) and second flipper member (1018). The first flipper member is slide -ably attached to the base. The first flipper member is also configured to selectively attach a first mandrel (1060) thereon and to rotate the first mandrel. The second flipper member is also slide-ably attached to the base. The first and second flipper members are slide-ably positioned select distances from each other on the base in embodiments. The second flipper member is further configured to attach a second mandrel thereon and to rotate the second mandrel.

摘要： 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.
