PI-SHAPED PREFORM WITH NON-LINEAR LEGS AND METHOD TO MANUFACTURE IT |
摘要 |
<p>A woven preform for a reinforced composite material, which may be woven flat and folded into shape. The preform has a three-dimensional weave architecture with weft fibers woven to provide layer-to-layer interlocking of layers of warp fiber as well as interlocking of fibers within each layer. One or more legs extend from a base, the base and legs each having at least two layers of warp fibers. The legs may be parallel or angled to each other and/or may move along a sine wave in the warp and/or weft direction. The outer ends of the base and/or the legs preferably have tapers formed from terminating layers of warp fibers in a stepped pattern.</p> |
