## Abstrad-Tensile tests have been performed on carbon/carbon composites made from carbon cloths and a pyrolytic carbon matrix and their failure surfaces were examined by scanning electron microscopy. The load-extension curves are characterized by three distinct regions: the applied load needed to

The work-of-fracture (ywOF) of carbon-carbon composites was measured for composites with 3-D woven fiber preforms, carbon felts, and chopped fibers. Maximum values were observed for the 3-D preforms and minimum values for the carbon felts. The values are also compared with similar data for graphites
The relations between chemical vapor deposition (CVD) parameters and the resultant pyrolytic carbon microstructures have been examined for matrix deposition in fibrous carbon substrates. The parameters considered are temperature (1200-145O"C), pressure (20-630 Torr), C/H ratio (l/4-1/14), total flow
AASTRACTS 331 ment. The electron microscope (both in the scanning and transmission modes) was used to examine the topography of both wet (60% HNOs, 118ยฐC) and dry oxidized (air, 700ยฐC) fibers as well as fracture surfaces of composites made with treated and untreated fibers. The flexural strength of
