Abstract

A small diameter steel-ball impact experiment was performed to study the impact resistance of the surface of glass plates bonded with glass fabric/epoxy lamina. Five kinds of materials were used in this study: soda-lime glass plates, glass/epoxy lamina(one layer)-bonded and unbonded glass plates, glass/epoxy lamina(three layers)-bonded and unbonded glass plates. The range of impact velocity was 40 120m/s. The maximum stress and absorbed fracture energy were measured on the back surface of glass plates. With increasing impact velocity, various types of surface cracks such as ring, cone, radial and lateral cracks took place in the interior near the impacted site of glass plates. The cracks drastically decreased with glass/epoxy lamina coating. The surface fracture behavior could be evaluated using the maximum stress and the absorbed fracture energy.

유리섬유/에폭시 복합재료로 피막한 유리판의 표면파괴거동을 연구하기 위하여 미소강구 충격실험을 수행하였다. 본 연구에서는 다섯 종류의 재료, 단순소다유리판(soda-lime glass plates), 유리섬유/에폭시박막(glass/epoxy lamina)을 1층 접착, 비접착한 시편과 박막을 3층 접착, 비접착한 시편을 사용하였다. 충격속도 범위 40∼120m/s에서 유리판 배면에서의 최대 응력과 흡수파괴에너지를 측정하였다. 충격 속도증가에 따라 링균열, 콘균열, 레이디얼 균열이 시편 내부에서 발생하였다. 복합재료 박막으로 피막한 결과, 소다유리판의 균열은 현저히 감소하였으며 측정한 최대 응력과 흡수파괴에너지를 이용하여 표면 파괴거동 특성을 평가할 수 있었다.
