Abstract
Multi-walled carbon nanotubes (MWNTs) were incorporated into precursor-derived ceramics made from a polysilazane. A ceramic nanocomposite reinforced with about 35 vol% of carbon nanotubes (CNTs) was fabricated by infiltrating CNT-preform with liquid-phased polymeric precursor followed by pyrolysis. The nanocomposite has a dense structure without micro-cracks. The results reveal that the nanocomposite has lower indentation hardness but higher fracture energy than non-reinforced ceramic from the microindentation tests results. The effect of the CNTs on the mechanical properties of the nanocomposite should be discussed accordingly.
