炭化ケイ素ウイスカー強化コーディエライト複合材料の機械的性質

抄録

The effects of whisker diameter and carbon coating to whiskers on the mechanical properties of SiC-whisker-reinforced cordierite composites were studied. The flexural strength of cordierite reinforced with whiskers of a small diameter was stronger than that with a large diameter. The fracture toughness of cordierite reinforced with whiskers of a small diameter was slightly larger than that with a large diameter. No significant effect of coating of whisker with carbon was observed on the flexural strength and fracture toughness of SiC-whisker reinforced cordierite composite.
