Abstract

In this paper, the repeated low-velocity impact response of woven S2-glass/epoxy composites is studied. The impacts were performed with energies from 18.4 to 59.2 J using a drop-tower apparatus, and a post-mortem analysis after each impact was employed to assess the impact response. A damage index was used to describe the changes in impact response due to repeated impacts. Finite element simulations considering both interlaminar and intralaminar failure modes were performed. The results showed that the impact force and bending stiffness decreased with the number of impacts, while impact duration and maximum central displacement increased. The shape of the damaged area was also affected. The numerical results showed that interlaminar damage initiated at most interfaces during the first impact, followed by in-plane propagation in the next impacts. Also, intralaminar damage initiated at the backside of the laminate, and then in-plane and through-thickness propagations followed until penetration occurred.

期刊介绍： "Advanced Composite Materials (ACM), a bi-monthly publication of the Japan Society for Composite Materials and the Korean Society for Composite Materials, provides an international forum for researchers, manufacturers and designers who are working in the field of composite materials and their structures. Issues contain articles on all aspects of current scientific and technological progress in this interdisciplinary field. The topics of interest are physical, chemical, mechanical and other properties of advanced composites as well as their constituent materials; experimental and theoretical studies relating microscopic to macroscopic behavior; testing and evaluation with emphasis on environmental effects and reliability; novel techniques of fabricating various types of composites and of forming structural components utilizing these materials; design and analysis for specific applications. Advanced Composite Materials publishes refereed original research papers, review papers, technical papers and short notes as well as some translated papers originally published in the Journal of the Japan Society for Composite Materials. Issues also contain news items such as information on new materials and their processing."
