Effects of Subzero Temperatures and Seawater Immersion on Damage Initiation and Growth in Sandwich Composites
Abstract
Progress to-date is described on the project "Effects of Subzero Temperatures and Seawater Immersion on Damage Initiation and Growth in Sandwich Composites." Funding for this two-year effort was received at Syracuse University (SU) in late February of 2007. The work since that tune has focused on obtaining materials and supplies, creating the infrastructure to do the work, and on performing preparatory and exploratory experiments and analyses. To this end, freezers have been purchased for storage of sandwich laminates at 0 deg., -20 deg. and -40 deg., test fixtures have been designed and are being fabricated at the SU machine shop, manufacturing supplies have been procured, and a vacuum-assisted resin transfer molding (VARTM) process for fabricating sandwich panel laminates has been successfully implemented. Work in-progress includes seawater immersion and freezing studies on core and sandwich panel specimens, as well as a preliminary evaluation of the proposed crack tip element based approach for predicting energy release rates for sandwich debonding and crack kinking out of the core-to-face sheet interface.
