Abstract

Carbon fiber reinforced carbon matrix composites (C/C) are promising in the aerospace fields. Characteristics of the interface between carbon fiber and carbon matrix are required to estimate the C/C strength. Therefore, Pyrolytic graphite (PG) and isotropic graphite were adopted as a model of carbon fibers, and phenolic resin was used as the matrix for this fundamental study to sort out the factors of bonding interface in C/C. The graphite plates were joined with the phenolic resin. One of the joined planes of the crystal orientation of the PG was parallel to the graphite base plane (P/P) and the other was vertical (V/V). Isotropic graphite was also joined (I/I). The resin was carbonized at 1773K, and the samples were heat treated at high temperatures up to 3173 K. In this paper, the bonding strengths of these specimens were determined by specially designed shear load test. The experimental results by this method were discussed in terms of thermal and crystalline conditions. Crystal structure and orientation of the bonding layer were observed by transmission electron microscope (TEM).
