Effects of Subzero Temperatures and Sea Water Immersion on Damage Initiation and Growth in Sandwich Composites
Abstract
Progress during the past six months is described on the project "Effects of Subzero Temperatures and Seawater Immersion on Damage Initiation and Growth in Sandwich Composites." Efforts during this period have focused on (1) assessing the effects of environment and impact damage on the flexural response of sandwich laminates, (2) linalizing the improved modified peel test and associated data reduction method for determining the debonding toughness of sandwich structures, and (3) using this new test to assessment the toughness of sandwich structures with different face sheet materials under a variety of environments. In the first focus area, the proposed test matrix has been completed and the data obtained are used to draw a number of conclusions about the effects of temperature, sea water saturation, and impact damage on the static strength, static stiffness, fatigue strength, fatigue stiffness and life of sandwich laminates. Work in the second and third focus areas has been completed. This work has been documented in one publication and a second is in preparation.
