Contrast and analyse of properties of carbon/carbon composites from different producers

摘要

This paper has studied the microstructure, graphitization degree, heat tranfer coefficient, hardness,rncompressive strength, flexural strength, interlaminar shear strength, friction and wear properties of differentrnspecimens that came from different producers such as DunloprnB.F.Goodrich Missier Bendix and CSU state keyrnlaboratory for powder metallurgy .The results show that as a superior carbon/carbon braking material, it must havernreasonable substrate and proportional rough laminar microstructure , high graphitization degree, as well as highrnthermal conductivity in the vertical direction of the friction surface in the composites. And the results also showrnthat we have get the ability to produce carbon/carbon composites for aircraft braking material compared with thernother companies that are very outstanding in this field.
