FRP层合板低速冲击损伤特性研究现状与展望

CURRENT STATUS AND PROSPECTS OF STUDY ON LOW VELOCITY IMPACT DAMAGED CHARACTERIZATION OF FIBER-REINFORCED COMPOSITE LAMINATES

纤维增强复合材料层合板(FRP)由于具有比强度高、比模量高、可设计性强等特性,在工程领域得到越来越广泛的应用。但是低速冲击造成的损伤对层合板力学性能的影响非常显著,导致其强度和刚度下降。本文针对近年来纤维增强复合材料层合板低速冲击作用下的损伤研究进行了综述和回顾,重点介绍了试验研究方法、模拟计算研究方法、FRP层合板损伤性能表征方法,并对有待于进一步研究的问题进行了展望。

Fiber-reinforced composite laminates have been widely used in engineering area because of its special properties,such as high specific strength,high specific stiffness and excellent designability.But the effect of damage caused by low velocity impact on the FRP is remarkable,which can reduce the strength and stiffness.The study on damage of fiber-reinforced composite laminates under low velocity impact in recent years is summarized and reviewed in this article.The main contents of the article are as follows...
