摘要

PROBLEM TO BE SOLVED: To perform reliable deceleration and stop of a car by providing a brake piece formed of a composite material prepared such that at least one kind of ceramic particles selected from a carbide having a grain size in a specified range, a nitride, and a boride is dispersed in a ceramic parent material. ;SOLUTION: A brake piece 30 is inserted in each through-hole 32 of a holding block 33 through a cylinder body 36 formed of heat resistant long fibers and protruding from each holding block 33 surface. Each brake piece 30 is formed of a composite material wherein ceramic particles of at least one selected from a carbide, such as titanium, having a grain size of 10-150μm, a nitride, such as titanium nitride, and a boride, such as titanium boride, are dispersed in a ceramic parent material selected from silicone nitride, silicone carbide, and sialon.;COPYRIGHT: (C)1998,JPO
