Abstract

휘스커 성분들 사이의 결합력이 강하고 복합화 기능이 향상된 휘스커 예비 성형체의 제조방법에 관한 것으로서, 휘스커 생성물을 r-아미노프로필트리메톡시실란과 메탄올로 구성된 결합제 용액 내에 균질 분산시키고, 균질 분산액을 여과 및 탈수시켜 습윤 휘스커 케익을 얻고, 습윤 휘스커 케익을 금형에 주입하고 가압 성형하여 예비성형체를 제작하고, 이를 400℃ 이상의 온도에서 약 30분간 가열하는 것으로 이루어지는 휘스커 예비 성형체의 제조방법.A method for producing a whisker preform having a strong binding force between the whisker components and an improved compounding function, wherein the whisker product is homogeneously dispersed in a binder solution composed of r-aminopropyltrimethoxysilane and methanol, and the homogeneous dispersion is filtered and dehydrated. To obtain a wet whisker cake, inject the wet whisker cake into a mold and press molding to produce a preform, which is heated at a temperature of 400 ° C. or higher for about 30 minutes.
