Abstract

헥사티탄산칼륨결정 및 이산화티탄결정이 혼합된 형태로 이루어진 복합상을 가진 판형상 다결정섬유는 티탄화합물과 칼륨화합물의 혼합물을 가열함으로서 용융물을 얻고, 상기 용융물을 냉각시켜 섬유덩어리를 얻고, 섬유덩어리를 수용성 산용액으로 처리하여 섬유는 칼륨함량을 1 내지 13.5중량%로 조절하고, 상기 결과의 섬유를 900 내지 1300℃에서 소성처리하는 공정에 의해 제조된다.A plate-shaped polycrystalline fiber having a composite phase composed of a mixture of potassium hexatitanate and titanium dioxide crystals is obtained by heating a mixture of a titanium compound and a potassium compound to obtain a melt, cooling the melt to obtain a fiber mass, and a fiber mass. The fiber is prepared by a process of adjusting the potassium content to 1 to 13.5% by weight with a water-soluble acid solution and calcining the resultant fiber at 900 to 1300 ° C.

상기 복합섬유는 자동차등의 브레이크 장치의 슬라이드부재용 마찰부재에 함유되는 섬유로서 바람직하다.The said composite fiber is suitable as a fiber contained in the friction member for slide members of brake devices, such as an automobile.
