Process for obtaining thermal-structural composites

摘要

The present invention relates to "improvements introduced into the process of obtaining a thermal-structural composite", obtained from a combination of various synthetic materials (F), after going through a bonding step (combination of materials), a temperature suitable for the fusion of said materials and heated and compressed into a mold of a specific size for each part to be molded under pressure, wherein the heat-structured composite is synthetic fiber molding (F), foam, etc., preferably diphenylmethane diisocyanate in a proportion of 30% to 80% Substrate (S) with non-woven (NW-TNT) + PE film + glass fiber + semi-rigid PU foam contained in a chemical formulation (FO) of (MDI) and methylene chloride (CM) in a proportion 20% to 70% obtained from the formation of, for the treatment of the heat-structural composite, a catalyst prepared from Dabco Cristal in a proportion of 1% to 30% is used, 70% to 99% of water is added, the substrate It is characterized in that (S), during the hot forming step, a finish (5) is added, and after said forming step, smaller complementary structural elements (6) are added.
