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.
Claims21
A hybrid reinforcement material comprising:
- a plurality of reinforcement fibers;
- and
- a plurality of carbon fibers comingled with said reinforcement fibers to form said hybrid reinforcement material, wherein said carbon fibers are coated with a compatibilizer.
A method of forming a hybrid assembled roving, the method comprising:
- comingling a plurality of reinforcement fibers and a plurality of carbon fibers, wherein said carbon fibers were previously coated with a sizing composition and then are post-coated with a compatibilizer, wherein said hybrid assembled roving has a thickness of from 0.5 mm to 2.0 mm.
A hybrid reinforced composite comprising:
- at least one hybrid reinforcement material comprising a plurality of reinforcement fibers and a plurality of carbon fibers, said reinforcement fibers and said carbon fibers being comingled, wherein said carbon fibers are coated with a compatibilizer;
- and
- a polymer resin matrix.
