Damage progression in non-crimp fabric composites

L.E. Aap, J. Varna and E. Marklund,     Swerea SICOMP and Luleå University of Technology, Sweden

Abstract:

In this chapter, prevailing damage mechanisms in in-plane loaded non-crimp fabric (NCF) composites, as well as out-of-plane impact-loaded and subsequent in-plane compression-loaded NCF composite structures, are presented and discussed in detail. Particular emphasis is on the identification of differences and similarities in failure mechanisms for NCF composites to those in traditional tape-based composites.
