Abstract: A method of continuously forming a composite structure comprised of a three-dimensional fabric including first and second sheets of fabric which face each other and which are connected by intermediate yarn, the method including providing a continuous supply of three-dimensional fabric; impregnating the three-dimensional fabric with resin which is thermoreactive; mating the three-dimensional fabric with a first outer strip which contacts the first sheet of fabric, and a second outer strip which contacts the second sheet of fabric to form a stratified structure containing the impregnated three-dimensional fabric; feeding the stratified structure along a path in a feed direction X which is straight; heating the stratified structure to at least partially polymerize the resin between the first outer strip and the first sheet of fabric and between the second outer strip and the second sheet of fabric, while the resin impregnating the intermediate yarn of the three-dimensional fabric remains substantially in the pla

Abstract: A method and an apparatus for the production of a three-dimensional textile (3), wherein the textile (3) is formed from two sheets of textile (5, 6) placed face to face and connected together by a plurality of threads (10), impregnated with resin and inserted between two layers (16, 17) so as to form a layered structure (1). This layered structure (1) is inserted between two dies (25, 26) of a heated press which is subsequently closed to allow the resin impregnating the structure to distribute itself uniformly. The layers (16, 17) are then attached by vacuum to the faces of the dies (25, 26) which are then opened through a first controlled distance within the limit of the elastic recovery of the three-dimensional textile (3). The outermost layers of the structure (1) are then polymerized by heating the dies (24, 26) while the resin impregnating the threads (10) remains in a plastic state.
