    Abstract: A method of producing a non-crimp fabric and a non-crimp fabric comprising a layup of fabric plies stitched together by a thread, at least part of which is fusible, is provided. The method can include heating the stitched plies to soften or melt the fusible thread. The use of fusible thread can act as an in situ binder within the non-crimp fabric and tension created by the unfused stitching may create channels for matrix resin infusion during manufacture.

  • Patent number: 7456119
    Abstract: This invention relates to a composite laminate, a layup and preform for such a composite laminate and to a method of manufacturing the composite laminate. The layup (28), preform and composite laminate (22) include at least one ply (20) which includes hairy yarn (10). The action of the hairy yarn (10) is to provide cross ply linking owing to the extension of fibers from the hairy yarn into spaces both within the ply and between the plies. The addition of resin matrix material (26) to layup provides a firm cross ply linkage to the composite laminate.
