ABSTRACT

Multidirectional reinforcement is aimed primarily at overcoming interlaminar weaknes, hence a major interest liesin the mechanical properties of multidirectional carbon/carbon composites. Mechanical properties depend on the typeof carbon fiber, the size of the fiber bundle, the spacing of the bundles, the angles of the bundles relative to the axes ofthe block, and matrix formation. In the present studies, PAN based carbon fiber preforms manufactured diferent size ofcoal tar pitch as matrix precursor was caried out. Scanning electron microscopy has ben used to study the fracturebehavior of composites. The size of unit cell of the preforms has considerably affected on the flexural properties aswell as microstructure of the carbon/carbon composites.
