Development of short carbon fiber/carbon matrix composites
- Auburn Univ., AL (United States)
Traditional carbon/carbon (C/C) composites have been primarily based on uni-directional, fabric and multi-directional carbon fibers. The cost of raw materials and processing difficulties have restricted the application scope of C/C composites. In the present investigation short carbon fiber reinforced carbon matrix composites (SFC/C) were processed by a compression molding technique. Carbon matrix densification was done by liquid impregnation of phenolic and pitch. The structure and properties of SFC/C composites were characterized by X-ray diffraction, optical & electron microscopy, thermogravimetry, electrical conductivity measurements and three point bending tests. The strength and modulus of these composites were found to be approximately 70 MPa and 20 GPa, respectively. The electrical conductivity values of SFC/C composites were found to be {approximately}10{sup 3} (ohm-cm){sup {minus}1} and the composites were stable in an oxidative atmosphere up to 550{degrees}C. Traditional polymer processing technique, which has the versatility of producing intricate shaped parts, may make it more cost-effective to use SFC/C composites in aerospace, automotive and bio-medical applications.
