Abstract
A method for making a discontinuous fiber molding compound from carbon fiber tow. The method involves using remnants of carbon fiber tows from spent carbon fiber spools. The remnants are chopped into pieces to form an assembly of chopped carbon fiber tows that are from 1 cm to 10 cm long. The chopped carbon fiber tows are then mixed with a powdered resin to form a blend of chopped carbon fiber tows and powdered resin. The blend is heated to soften/melt the particles of resin and then cooled to form a discontinuous fiber molding compound.
