Evaluation of the tensile properties and optimum condition of manufacturing of carbon needle punched perform by material composition and processing parameters

탄소 니들펀칭 프리폼의 소재조성 및 공정변수에 따른 인장 특성평가와 제작 최적화

The effect of punching density and material composition on the tensile properties and optimum condition of manufacturing of carbon needle punched perform was studies. The interlaminar tensile strength were increased but the intralaminar tensile strength were decreased with increasing punching density. In the case of the performs composed of continuous oxi-PAN fabrics, there was a considerable improvement of the interlaminar and intralaminar tensile strength.
