PRE-IMPREGNATED SHEET WITH BOUND FIBERS

摘要

The invention concerns a pre-impregnated sheet material comprising a thermosetting resin and a fibrous structure bound with a soluble solvent in said thermosetting resin. During the hot-process and pressurized production of the composite material, the binder is solubilized and releases the fibers of the fibrous structure which may then creep and fill up the entire composite-manufacturing mould. A fibrous structure with continuous fibers or chopped fibers may be used, The binder enables the fibrous structure to be manipulated, wound and stored before it is incorporated into a pre-impregnated material.
