LIFETIME PREDICTION OF GLASS FIBER/DERAKANE 411-350 COMPOSITES

摘要

The goal of the present effort is to develop and verify a lifetime prediction approach for glass fiber reinforced DERAKANE 411-350 composites subjected to fatigue loading, as well as moisture aging. The approach taken is to use fatigue lifetime data taken from samples that were not aged and use it in conjunction with long-term immersed aging data (for a different laminate), as inputs to a residual strength based lifetime prediction scheme entitled MRLife. We will compare our predicted results to those measured experimentally, and comment on discrepancies observed.
