Strength of fabric reinforced Blackglas composites
- Drexel Univ., Philadelphia, PA (United States)
In brittle matrix composites the role of matrix porosity; interface; and matrix/fiber properties degradation due to processing are especially critical for the strength of the composite. In this paper, the Fabric Geometry Model (FGM) is modified to predict the strength of fabric composites. An incremental strain approach in conjunction with strain energy criterion is presented in order to account for the potentially nonlinear behavior of the materials, as seen in the experimental stress-strain curves of Nextel/Blackglas, composites. The failure of the composite is determined by use of a modified maximum strain energy criterion, which is based on the relative magnitudes of the various energy terms in corresponding direction. The effects of porosity, microcracks, fiber and matrix degradation, and fiber/matrix interface are also considered in the modified model.
