BRAKING MATERIAL AND MANUFACTURING METHOD THEREOF
To provide a braking material excellent in thermal shock resistance and abrasion resistance, and having improved toughness and longer service life, and a manufacturing method thereof.SOLUTION: The braking material comprises: a substrate made of a silicon carbide composite material containing carbon fibers; and a slide layer formed at least in a region of the surface of the substrate where a brake pad slides, and not containing carbon fibers. The slide layer includes: first silicon carbide particles 1 of a first particle size; a silicon carbide sintered part 2 connecting the first silicon carbide particles 1 of the first particle size, and formed of second silicon carbide particles having a second particle size smaller than the first particle size; and silicon 3 and carbon 4 formed in the gap where the silicon carbide particles of the first particle size and the silicon carbide sintered part are not formed.SELECTED DRAWING: Figure 2
【課題】耐熱衝撃性、耐摩耗性に優れ、靱性がより向上し、より長寿命の制動材およびその製造方法を提供すること。【解決手段】この制動材は、炭素繊維を含有する炭化珪素複合材からなる基体と、前記基体表面における、少なくともブレーキパッドが摺動する領域に形成された、炭素繊維を含まない摺動層とを備えた制動材であって、前記摺動層が、第１の粒径の第１の炭化珪素粒子１と、前記第１の粒径の第１の炭化珪素粒子１を連結する、前記第１の粒径よりも小さい第２の粒径の第２の炭化珪素粒子で形成された炭化珪素焼結部２と、前記第１の粒径の炭化珪素粒子と前記炭化珪素焼結部が形成さない隙間に形成されたシリコン３及びカーボン４とを含む。【選択図】図２
