Abstract:
A hybrid reinforcement material (18) is disclosed that includes a plurality of reinforcement fibers (12) and a plurality of carbon fibers (14) comingled with the reinforcement fibers (12). The reinforcement fibers (12) are selected from natural fibers, organic fibers, and inorganic fibers and form a single hybrid assembled roving with the carbon fibers (14). The carbon fibers (14) are post-coated with a compatibilizer. The hybrid assembled roving (18) may be formed using a hybrid of glass and carbon fibers.
