Abstract
Abstract Textile structure based on filaments impregnated and/or coated with thermoplastic material (FIT filaments) is formed from at least two layers of such FIT filaments, arranged perpendicularly to one another in the manner of a warp and a weft, but without being interlaced, and a binding weave consisting of a warp and a weft holding each of the FIT filaments in position. The textile structure is particularly applicable to the production of laminates exhibiting high mechanical stength.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
174 words
Textile structure comprising at least two stacked layers of FIT filaments, each of said filaments consisting of a core or reinforcement impregnated with or having a coating of thermoplastic material so as to be of relatively large diameter, the filaments in each of said layers extending parallel to one another and the filaments of each respective one of said layers being non-interlaced with the filaments of each of the other respective said layers so that said layers of FIT filaments exhibit a planar configuration, and the filaments of each one of said layers extending in a direction perpendicular to the direction in which the filaments of another of said layers extend, and a binding weave binding said layers of FIT filaments together, said binding weave consisting of a warp and a weft of threads having a diameter smaller than the diameter of said FIT filaments, said binding weave securing said filaments in position relative to one another in a manner in which the planer configuration exhibited by said layers of FIT filaments is maintained.
Claim 2
Dependent Claim
174 words
Textile structure comprising at least two stacked layers of FIT filaments, each of said filaments consisting of a core or reinforcement impregnated with or having a coating of thermoplastic material so as to be of relatively large diameter, the filaments in each of said layers extending parallel to one another and the filaments of each respective one of said layers being non-interlaced with the filaments of each of the other respective said layers so that said layers of FIT filaments exhibit a planar configuration, and the filaments of each one of said layers extending in a direction perpendicular to the direction in which the filaments of another of said layers extend, and a binding weave binding said layers of FIT filaments together, said binding weave consisting of a warp and a weft of threads having a diameter smaller than the diameter of said FIT filaments, said binding weave securing said filaments in position relative to one another in a manner in which the planer configuration exhibited by said layers of FIT filaments is maintained.
