Abstract
A process for producing a carbon sheet molding compound (SMC). An SMC manufacturing line including at least one conveyor line for laying up SMC resins on a carrier film is provided. A chopped carbon fiber which is evenly distributed using dehumidified supply air and using a pressurized air venturi apparatus which is used to debundle and randomize the carbon fibers, onto the resin on the carrier film as the carrier film moves along the conveyor.
