<p>PCT No. PCT/FR90/00280 Sec. 371 Date Dec. 12, 1990 Sec. 102(e) Date Dec. 12, 1990 PCT Filed Apr. 17, 1990 PCT Pub. No. WO90/12911 PCT Pub. Date Nov. 1, 1990.The invention relates to a textile structure comprising a superposition of unidirectional layers of yarns, the directions of which are crossed in relation to one another and which are tied by tying yarns. According to the invention, the number of superposed layers is at least equal to. The tying rate lies between 2 and 15%, approximately, and each tying yarn (20) ties at least one set of yarns of superposed layers, this set being defined by at least a first yarn (24) of a first layer (16) and at least a second yarn (25) of a second layer (19). The second yarn (25) is offset in relation to the first (24), and the connection of the layers is thus sufficiently loose in order to keep the structure in position and allow it to deform.</p> |
