摘要

Process for preparing a prepreg sheet, sheets of prepreg and manufacturing process of a composite material with matrix termoendurecida. The invention relates to a prepreg sheet comprising a thermosetting resin and a fibrous structure linked by a solvent soluble in said thermosetting resin.During manufacture, the hot and under pressure of composite material, the binder solubiliza and releases the fibers of the fibrous structure that can then flow and fill the entire mould manufacture of composite. You can use a fibrous structure with continuous filament or chopped strands.The binder can handle, folding, storing the fibrous structure before incorporating it into a prepreg.
