使用复合预浸带制作弯曲复合结构的方法
Abstract:
提供了制作具有弯曲腹板和至少一个弯曲法兰的复合加强件的方法。基本笔直长度的单向预浸带(30)被放置在载体(32)上。至少一个弯曲法兰是通过使用载体以将带的第一部分操控到第一弯曲工具表面上而成型的。弯曲腹板是通过使用载体以将带的第二部分成型到第二弯曲工具表面上而成型的。
Abstract(English):

A method is provided of fabricating a composite stiffener having a curved web and at least one curved flange. A substantially straight length of unidirectional prepreg tape (30) is placed on a carrier (32). The at least one curved flange is formed by using the carrier to steer a first portion of the tape onto a first curved tool surface. The curved web is formed by using the carrier to form a second portion of the tape onto a second curved tool surface.
