Experimental Study of a Delaminated Sandwich Composite Subject to Impact and/or Compressive Loading

Abstract

Symmetric sandwich composites are very attractive for use in various structural applications due to their low weight and high flexural stiffness. This research focuses on experimental studies of the damage tolerance of a sandwich composite with delamination subjected to low- energy impact and/or compressive loads. Tests are performed to correlate delamination length with failure loads and loss of damage tolerance. The impact force history is used to determine the work, kinetic energy and momentum imparted to the sample in order to gain an understanding of the mechanisms involved in damage due to impact.
