<p>PCT No. PCT/NL91/00109 Sec. 371 Date Feb. 23, 1993 Sec. 102(e) Date Feb. 23, 1993 PCT Filed Jun. 25, 1991 PCT Pub. No. WO92/00182 PCT Pub. Date Jan. 9, 1992.This invention relates to a process for manufacturing composites and laminates reinforced with continuous or long fibers and/or filaments. The process includes the subsequent steps of (a) forming a preform of reinforcing material by arranging a green tape, ribbon, sheet or cloth including a number of continuous longitudinally oriented fibers or filaments which are spaced from each other by uniformly distributed particles, bonded by a flexible binder, (b) removing or converting a major portion of the binder into matrix material and, if applicable, (c) filling the voids and cavities with matrix material. Further, this invention relates to a process for manufacturing composites and laminates reinforced with chopped-aligned fibers and/or filaments, which includes chopping a green tape or ribbon as defined above, mixing the chopped tape or ribbon with a binder, lubricant and/or matrix material and forming mouldings from this mixture by any moulding method.</p> |
