ABSTRACT:
A fiber-reinforced plastic structure is obtained by weaving fibers in one direction about one or more spacing members located angularly to the fibers. The fibers may be either warp or woof stands, the spacing member serving as woof when the fibers from warp strands, and as warp when the fibers form woof strands. The removal of the spacing member leaves relatively large open channels forming, in effect, a multi-wall hollow structure. The resultant structure may be partially or completely treated with a plastic resin system prior to or after the removal of some or all of the members. The solidified resin reinforced structure may be filled with a foam-in-place plastic, and it may be stacked in layers to provide additional thickness with reinforcing fibers running in different directions for additional strength. Some fibers may extend from one ply into an adjacent ply or into more remote plies. The hardened structure may also be stacked to provide a honeycomb configuration and may be sliced into thin sections with sheets of additional fiber-reinforced plastic material on each side or each end to produce a structure of high strength-to-weight characteristics.
