Abstract
본 발명은 내마모성 및 내열성이 우수하고 경량합금과 강화섬유의 예비성형체로 이루어진 경량의 복합재료에 이용되는 예비성형체의 건조방법에 관한 것으로, 세라믹재질의 강화섬유에 결합제와 용매등을 섞어 혼합시킨후 일정한 형상에 주입한 다음 진공 또는 자연발수방식으로 이 강화섬유를 1차로 성형시킨다. 이어 고진동의 전자파를 이용하여 상기 1차성형된 예비성형체를 신속하게 가열건조시켜 균일한 예비성형체를 제조함에 따라 예비성형체의 내 · 외부 강화섬유의 결합정도와 강도의 균일화가 이루어져 제질의 균일화를 도모할 뿐만 아니라 건조공정의 단축으로 전체제조 공정을 단축하도록 되어 있다.The present invention relates to a method for drying a preform used in a lightweight composite material having excellent abrasion resistance and heat resistance and consisting of a preform of a light alloy and a reinforcing fiber, wherein a binder and a solvent are mixed with a ceramic reinforcing fiber, and then mixed. After injection into a certain shape, the reinforcing fibers are first molded by vacuum or water repellent. Subsequently, the primary molded preform is rapidly heated and dried using high vibration electromagnetic waves to produce a uniform preform, thereby uniformizing the bonding degree and strength of the internal and external reinforcing fibers of the preform, thereby achieving uniformity of materials. In addition to shortening the drying process, the entire manufacturing process is shortened.
