PREPREG FOR DECORATIVE COMPONENTS WHICH ARE HIGHLY HEAT-RESISTANT, TRANSPARENT, COLORLESS AND FREE OF DEFECTS, SUCH AS SPOTS AND DOTS, AND MANUFACTURING METHOD THEREOF

摘要

A method for obtaining prepreg - fiber-reinforced composite materials intended for making "Carbon Look" decorative components, characterized by transparency and total absence of color, and free of white spots and/or dots, provides the use of a Lewis acid with latency properties, such as BCl₃.(N,N-dimethyl octylamine), as polymerizing catalyst of the epoxy resins used as matrix. The decorative components, after the curing process, in addition to being transparent, colorless and free of defects, such as white spots and/or dots, are also highly heat-resistant, because the cured composite obtained from prepreg manufactured with an appropriately formulated matrix, reaches high glass transition temperature values.
