라미네이션 접합을 이용한 공작기계용 안전가드의 필름에 따른 내충격성에 관한 연구

Abstract

Simple adhesive-type safety guards that are currently used are prone to inflow of cutting oil over time, which causes the polycarbonate to shrink. To address this problem, safety guards fabricated by the lamination method are used to prevent inflow of cutting oil and improve impact resistance. Such safety guards are expected to have different impact resistances depending on the mechanical strengths of the lamination films. Impact tests and analysis are thus used to confirm these impact resistance differences based on the bonding strengths of the lamination films. It is noted that the ductility of the material must be reflected in its bonding force and not the mechanical strength. In this study, the results were examined according to the bonding strengths of the lamination films analytically.
