Abstract
본 발명은 기계적 특성이 우수한 세라믹 섬유 강화 금속 복합체용 예비성형체를 제조하는 방법을 제공하는 것을 목적으로 한다. 알루미나, 실리카 및 지르코니아를 포함하는 알루미나 실리카 섬유를 탈립처리하는 단계, 상기 알루미나 실리카 섬유를 콜로이달 실리카중에 분산시켜 이 콜로이달 실리카를 교반하는 단계, 상기 콜로이달 실카를 포함하는 상기 알루미나 실리카 섬유를 이용하여 소정크기의 예비성형체를 형성하는 단계, 및 상기 예비성형체를 건조한 후 소성하여 개개의 알루미나 실리카 섬유를 콜로이달 실리카에 의해 결합시키는 단계를 포함하는 예비성형체의 제조방법에 있어서, 상기 알루미나 실리카 섬유의 어스펫 비가 40 내지 60인 것을 특징으로 한다.An object of the present invention is to provide a method for producing a preform for a ceramic fiber reinforced metal composite having excellent mechanical properties. Deggregating alumina silica fibers comprising alumina, silica and zirconia, dispersing the alumina silica fibers in colloidal silica and stirring the colloidal silica, using the alumina silica fibers comprising the colloidal silica Forming a preform of a predetermined size, and drying and calcining the preform to bond individual alumina silica fibers with colloidal silica, wherein the alumina silica fibers It is characterized in that the earth ratio is 40 to 60.
