Mechanical properties improvement of carbon/carbon composites by two different matrixes

Carbon/carbon (C/C) composites with two different matrixes of pitch carbon and pyrolytic carbon were fabricated using 2-dimensional (2D) carbon felts preform. In order to study the effects of matrixes on mechanical properties, C/C composites with single matrix of pitch carbon were prepared. The mechanical properties were tested on CMT5304-30KN universal testing machine. Polarization microscope and scanning electron microscope were used to...
