摘要： Woven preforms, for example those used for jet aircraft engine fancases, may need additional stiffeners to improve the strength and/or dynamic performance of the preform assembly, as well as to serve as attachment points. The present invention describes several improved woven preforms that include circumferential or axial stiffeners, as well as methods of manufacturing the same. One embodiment includes circumferential stiffeners added to a woven preform. Another embodiment includes sub-preforms with integral flanges that combine to make integral stiffeners. A further embodiment includes an intermediate stiffener wrapped onto a base sub-preform wrap, wherein the intermediate stiffener wrap incorporates intermediate stiffeners. Another embodiment incorporates bifurcations in one or more layers of an outermost wrap of a multi-layer fabric composite that forms a preform, wherein the bifurcated outer wrap is folded to form stiffeners that may be oriented circumferentially or axially.

摘要： Disclosed are methods and related compositions for producing a positive-locking load application for rod-shaped fiber composite structures, and the design thereof.
The present invention concerns a method for producing a positive-locking load application for tension-compression rods from a fiber plastic hollow structure by means of an outer sleeve. In this process, a force pushes the fiber plastic hollow structure at least partially over at least one force application element, which is provided with at least one undercut to create a positive-locking connection. An object of the present invention is attained through local heating of the fiber plastic hollow structure to the point of plasticity of the fiber plastic hollow structure, at least in the region of the undercut(s) of the force application element, and application of at least one outer sleeve to the fiber plastic hollow structure in the region of the force application element.-

摘要： A three-dimensional gap-filled preform and a method of forming a three-dimensional gap-filled preform. The preforms comprise a base section of all integrally woven layers, a portion of that base separated into three sections, the outer two sections comprising integrally woven layers, and the middle section comprising an integrated gap filler. The integrated gap filler may comprise a center section of one woven layer, independently woven layers, integrally woven layers, or a plurality of layers of warp fibers that are not interwoven with weft fibers. The layers of the integrated gap filler compress or crumple up in the middle section and fill the formed gap or gaps, while the woven layers of the outer sections are folded to form the shape of the preform.

摘要： The present invention generally relates to a woven preform for reinforced composite materials and a method of making thereof. Specifically, the present invention is a method of machine weaving fiber preforms for polymer matrix composites that consist of closed perimeters with multiple intersecting members in their interiors. More specifically, the invention is a woven preform and a method of forming thereof with closed cells at the outer edges with continuous hoop reinforcement in each cell of the preform. The woven preform is woven flat in both the warp and weft directions, and then unfolded to achieve the final shape of the structure, and can be processed into composite structural components using known methods such as resin transfer molding or chemical vapor infiltration. Thus, complicated shapes of all sizes can be woven on a conventional loom using the instant method.
