A PROCESS FOR THE MAKING OF COMPOSITE MATERIAL PRODUCTS HAVING REINFORCING LAYERS AND RESIN

摘要

There is provided a process for the making of composite material products, said products comprising a layered structure comprising at least one reinforcement layer made of fibers or fibrous fabric, and at least one layer of resin that impregnates said at least one reinforcement "fibrous layer within a mold, the process is characterized in that it comprises the following steps: Pretreatment of said reinforcement fibers or fabric through pre-impregnation with only a catalyst compatible with said resin; - Pretreatment of said resin by diluting with a compatible diluent until a predetermined viscosity; Addition of a catalyst to the pretreated resin; Arrangement of said pre-preg reinforcement fibers or fabric with only the catalyst inside of said mold; and - Impregnation of said pre-preg reinforcement fibers- or fabric through said resin within in said mold. It is also provided a product obtained by the present process.
