| titleOfInvention | Modification of continuous carbon fibers during precursor formation for composite materials with enhanced moldability |
| abstract | A method of producing continuous carbon fibers for composites having enhanced moldability is provided. As the precursor fiber is formed, discrete regions are introduced into a continuous precursor fiber comprising an acrylic polymeric material such as Polyacrylonitrile (PAN). The precursor may be a non-homogeneous fiber having a second dissimilar material interspersed in discrete regions with the acrylic polymer material. Alternatively, the precursor may be a non-homogeneous fiber, wherein the laser is applied to the acrylic polymer material in discrete regions to cause local molecular damage. After heating the continuous precursor fiber for carbonization and/or graphitization, the precursor forms a continuous carbon fiber having a plurality of discrete regions of weakness. These relatively weak areas provide non-contiguous discontinuities that reduce the stiffness and increase the moldability of the carbon fiber polymer composite while maintaining a high strength level. Carbon fiber polymer composites incorporating continuous carbon fibers having a plurality of discrete non-contiguous areas of weakness are also provided. |
