In this project, a new carbon fiber composite manufacturing process has been demonstrated which has exhibited favorable fabric formability characteristics as compared to traditional woven materials. This new material combines Fibrtec’s flexible coated tow, FibrFlex®, with DuPont's Rapid Fabric Formation (RFF) technology and a proprietary DuPont polyamide resin, all supported by Purdue University’s extensive modeling and characterization capabilities. The coated tow material is a partially impregnated carbon fiber/polyamide composite tow where the carbon fiber is not fully wetted with the polyamide, yielding a more flexible tow material than one that is fully impregnated. The RFF process is an ultra-fast way of manufacturing fabrics with tows in varying orientations without the need to lift the tow during processing. Experiments, modeling, and simulations, all have shown that this process/materials combination is a potential method for producing lower cost continuous fiber reinforced polymer (CFRP) materials that conform well during molding with outstanding physical properties.
