“…The composites were heat treated at high temperatures (THT > 25000C) in order to graphitize the fibers and the matrix. Different types or preparations of C/C composites used in other studies include three dimensional fiber weaves [1], chemical vapor deposition [2], plasma etched CVD [3] and carbon fiber-epoxy materials [4]. A recent review of C/C composites has been given by Fritz et al [51.…”
