1451 C/C複合材料の繊維-母相界面の微細組織観察(S07-3 セラミックスおよびセラミックス系複合材料III,21世紀地球環境革命の機械工学:人・マイクロナノ・エネルギー・環境)

The effects of heat treatment on fiber/matrix interface microstructure of carbon-carbon (C/C) composites were examined. The fiber/matrix interface morphology was observed by optical microscope, scanning electron microscope and atomic force microscope. The microstructures were observed by transmission electron microscope in detail. In samples heat-treated at more than 1273K, the matrix with changed morphology was observed between fibers. In addition, in samples heat-treated at more than 1873K, the grain structures were observed between fibers, and the grains grew with increasing heat treatment temperature. This matrix with changed morphology had turbostratic structure,while the matrix without changed morphology had amorphous structure.
