树脂基复合材料基于其比刚度、比强度、可设计性以及整体成形等诸多优点,在航空航天领域获得了广泛的应用。目前,飞机承力构件中最重要、用量最大的复合材料品种当属层合板形式的热固性树脂基复合材料。在其生产制造过程中,常存在许多不确定性因素,使得复合材料结构中存在分层、气孔、孔隙等诸多缺陷,复合材料在服役过程中即使受到低能冲击也很容易引发多种形式的损伤。据有关报导统计,复合材料层合板在加工、装配和使用过 Based on its specific stiffness, specific strength, designability and overall forming, resin-based composites have been widely used in the field of aerospace. At present, the most important and largest amount of composite materials used in aircraft load-bearing components belong to the thermosetting resin-based composite materials in the form of laminates. In its manufacturing process, there are often many uncertain factors, making the composite structure of stratification, porosity, porosity and other defects, composite materials in service even under low-energy impact is also very easy to trigger a variety of forms of damage . According to the report statistics, composite laminates in the processing, assembly and use
