Effects of Subzero Temperatures and Sea Water Immersion on Damage Initiation and Growth in Sandwich Composites

Abstract

Results are discussed for the project "Effects of Subzero Temperatures and Sea water Immersion on Damage Initiation and Growth in Sandwich Composites." This research project focused on (1) assessing the effects of environment and impact damage on the flexural response of sandwich laminates, (2) developing an improved test and associated data reduction method for determining the debonding toughness of sandwich structures, and (3) using this new test to assess the toughness of sandwich structures with different face sheet materials under a variety of environments.
