Low- and medium-velocity impact as a cause of failure in polymer matrix composites
R. Olsson, Swerea SICOMP AB, Sweden
This chapter gives an overview of causes and effects of damage due to low- and medium-velocity impact. Typical features of impact damage are described, with focus on tape prepreg laminates. The relation between impact response and impactor/plate mass ratio is explained and appropriate analytical response models outlined. Experimental observations of the behaviour of impact damage under load and its effect on strength and buckling are described. A brief discussion is also provided on the application of computational methods to impact on composites, and issues needing attention are highlighted. The chapter is ...
