摘要/Abstract

摘要： 使用试件为单向层合板和多向层合板两种类型的玻璃纤维增强环氧树脂基复合材料层合板,采用自由落体式冲击试验机进行低能量冲击,以及超景深显微镜对损伤形貌进行特征描述。引入低能量冲击关系因子K,建立冲击能量与损伤凹坑深度量化关系,该量化关系可使冲击能量与损伤形貌特征相对应。所建立的凹坑深度与冲击能量的关系,既可以根据测量冲击凹坑深度反推出冲击时的能量值,也可以根据冲击能量预判结构的损伤情况。

关键词: 低能量冲击, 外表面损伤, 特征描述, 凹坑深度, 量化关系, 关系因子

Abstract: In this paper, two types of glass fiber reinforced epoxy composites laminated board with unidirectional plate and multidirectional plate are used. The impact test was performed using free fall impact testing machine. Digital microscope was used to describe the damage morphology. By introducing factor K and establishing a quantitative relationship between the different impact energies and the pit depth, the relationship and the impact damage morphology characteristics under different impact energy are compared. According to the relationship between the depth of the pit and the factor K, the energy value of the impact is measured by measuring the pit depth. According to the impact energy value, the damage of the structure can be judged by experience.

Key words: low-energy impact, external surface damage, feature description, depth of pit, quantitative relation, relational factor
