GMT-Sheet의 압축비에 따른 기계적 특성에 관한 연구

Abstract

GMT-Sheet strong point because peculation subject matter the PP which is a materials and the glass-fiber are the pricecomparis on cheap are and the rigidity and tenacity excellent are point. Recently, the union it is developed the random GMT-Sheet and the one sided direction GMT-Sheet which the UP(gread-unidirection gread) which it makes used. Specially, it combines the inorgaric matter and the organic matter well and the GMT-Sheet which is produced will get near only the bay knows on strength level of thermosetting composite the productivity which is indicated with vulnerability of thermosetting composite, recycle characteristic, the inside shock characteristic back is excellent. And the strength, the hardness and the chemical resistance which it has a many strong point and thermo plastic with the basic material because of description below currently it is a composite which the attention it is receiving most from the side of re-application. With this the application it was becoming larger with the automobile parts to use the quality of the GMT-Sheet application it is coming to be wide even at non-automobile parts. In this study, GMT-Sheet it is used in the bumper of the automobile it measures the tensile strength which it follows to the random GMT-Sheet and the one sided direction GMT-Sheet each compression ratio. And the random GMT-Sheet and the one sided direction GMT-Sheet it does a high temperature compression press formation together and the tensile strength which it follows in compression ratio it measures.
