玻璃纤维增强铝基复合材料作为一种极具吸引力的先进航空航天材料，极有可能面临各种钝化缺口损伤的挑战。本文对具有圆形和方形钝缺口的环氧层压板进行了拉伸试验。探讨了缺口直径、缺口拐角半径、离轴角等缺口几何形状对玻璃钢增强环氧层合板拉伸性能的影响。基于修正的点应力准则，经验性地构造了表示缺口损伤影响区域的特征距离函数，用于预测圆形缺口玻璃夹层铝基复合材料的剩余强度。对于方形缺口的层合板，其强度与具有外接圆缺口的层合板的强度几乎相同。此外，还研究了两种断口形态随缺口几何形状的变化，并分析了金属化学去除后层间分层损伤的演化。
Glass laminate aluminum reinforced epoxy, as an attractive material for advanced aerospace applications, is most likely to face the challenge of various blunt notched damages. In this paper, the tensile tests of the glass laminate aluminum reinforced epoxy with circular and square blunt notches are conducted. The effects of notch geometry, such as notch diameter, notch corner radius, and off-axis angle, on the laminated tensile behaviors of glass laminate aluminum reinforced epoxy laminate are explored. A characteristic distance function representing the damage-affected region of notch is empirically constructed to predict the residual strength of the circular notched glass laminate aluminum reinforced epoxy based on a modified point stress criterion. For the square notched laminate, the strength is almost equal to that of the laminate with its circumscribed circle notch. Furthermore, the variation of two fracture patterns observed with the notch geometry is studied, and the evolution of the interlaminar delamination damage is analyzed after the metal chemical removal.
