Composite Materials for Advanced Global Mobility Concepts
Abstract
A 3-D stress and strain model of woven fabric composites based on Reissner's variational principle was developed and the model included 29 unknown variables. Strength predictions were also included, obtained by introducing penalty energy terms. The model results show good agreement when compared with woven composite experiments and flat laminate experiments and models. This agreement includes moduli, strength, and failure modes. Similar 3-D modeling of graphitic foam structures was initiated using the tetrahedral strut geometry. The basic premise for the graphitic foam processing model was also laid out.
