Manufacture of Prepreg with Photo-curing System

광.열경화 prepreg 제조 연구(I)

UV curing technology becomes important in various sectors of applications due to the high efficiency, environmental protection and saving energy. Above all, It is necessary to consider the formulation of glass fiber sizes in some detail to achieve this study since they are governed by the products to be made and their performance in the composites made form them. The effect of glass fiber sizes against UV curing system was investigated by the method of changing size formulation. Nanosil 700 was used in order to increase curing efficiency. Yellow effect was not observed at the 1% fiber sizer content.
