Lm. Manocha, THE EFFECT OF HEAT-TREATMENT TEMPERATURE ON THE PROPERTIES OF POLYFURFURYL ALCOHOL BASED CARBON-CARBON COMPOSITES, Carbon, 32(2), 1994, pp. 213-223
It is proposed that the microstructure of the matrix in carbon-carbon
composites develops as a result of the fiber-matrix bonding at polymer
stage and subsequent development of stress during carbonisation. The
present experimental studies give an account of the microstructural de
velopment with heat treatment temperature of the composites. Composite
s made with surface-treated and non-surface-treated carbon fibers resu
lt in quite distinct matrix structures. These in turn are found to hav
e controlling effects on the flexural strength and oxidation resistanc
e of the ultimate carbon-carbon composites. Composites heated to aroun
d 2000-degrees-C are found to possess high flexural strength and low o
xidation rates.
