摘要

摘要本文提出了复合材料抗低速冲击的概念。给出了复合材料层合板在低速冲击作用下凹痕深度与冲击能关系的三种现有表达式(双线性、抛物线和指数)。由于这些表达式存在一些缺陷，本文建立了新的冲击能与冲击凹痕之间的假定函数。通过现有的ASTM D 7136试验和模拟分析，验证了新表达式，并很好地解释了复合材料凹痕形成的性质。结论体现在结尾部分。

Research and analysis on low-velocity impact of composite materials

Abstract In this article, the concept of low-velocity impact resistance in composite materials is presented. Three existing expressions (e.g., bilinear, parabola, and exponential) that show the relationship between the dent depth and impact energy of composite laminates subjected to low-velocity impact are presented. Because of some flaws in these expressions, new supposed functions between impact energy and impact dent have been established. By means of existing ASTM D 7136 tests and simulation analysis, the new expressions are verified, and the nature of dent formation in composite materials is well explained. The conclusion is reflected in the ending part.

期刊介绍： Science and Engineering of Composite Materials is a quarterly publication which provides a forum for discussion of all aspects related to the structure and performance under simulated and actual service conditions of composites. The publication covers a variety of subjects, such as macro and micro and nano structure of materials, their mechanics and nanomechanics, the interphase, physical and chemical aging, fatigue, environmental interactions, and process modeling. The interdisciplinary character of the subject as well as the possible development and use of composites for novel and specific applications receives special attention.
