Effects of precursor thermal aging and fiber arrangement on the properties of carbon/carbon (C/C) composites
- National Tsing Hua Univ., Hsin-Chu (Taiwan, Province of China)
Carbon/carbon composites fabricated by the pyrolysis of high strength carbon fiber fabrics reinforced phenolic resin were investigated. A liquid impregnation process has been used to fabricate composite precursor for 2-D carbon/carbon composite and an unique pultrusion process also used to fabricate the 1-D carbon/carbon composite precursor. Effects of thermal aging of the precursor on flexural strength of the resulted carbon/carbon composites are studied. Results shows that suitable thermal aging improves the flexural properties of carbon/carbon composites in this study. And based on the SEM examination and flexural tests, they show that the 2-D plain woven fiber arrangement results the significant degradation of the carbon fiber and the decreasing of composites flexural properties.
