Abstract

See full text

A process to clean carbon fiber fabric of a pre-applied sizing, while simultaneously activating or preparing the fabric to receive a polymer resin is described. The cleaning process and chemistry combines an enzymatic cleaning solution with an oxidizing agent. The enzymatic solution strips the fibers of lubricants, surfactants, and other chemicals of the sizing which might otherwise interfere with interfacial properties and bonding of the fabric to the matrix resin. The inclusion of an oxidizing agent concurrently adds hydroxyl groups to the surface of the fabric allowing for the grafting of organic copolymers to the surface of the fabric, the copolymer being chosen based upon the desired polymer resin. This process provides a customized finished carbon fiber fabric to bond to a specific polymer resin, without interference resulting from an inadequate fiber sizing chemistry. In this way, a customizable finished fabric may be manufactured.
