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.
