Fabrication and Mechanical Properties of Unidirectionally Reinforced Carbon-SiC Composites.

In this paper, the methods of improving mechancal properties of SiC composites reinforced with unidirectionally oriented carbon fibers (Ct/SiC) were discussed. Fibrous preform of Ct/SiC composite was formed by filament winding and consolidated by hot pressing. Mechancal properties of Ct/SiC depended strongly on characteristics of carbonfibers, fabrication conditions and fiber/matrix interfacial properties. For obtaining the excellent Ct/SiC composite, it is important to choose carbon fibers with high durability under the processing, and it is necessary to fabricate the Ct/SiC composite with high density and appropriate fiber/matrix interfacial properties.
