Biaxial Failure Analysis of Graphite Reinforced Polymide Composites
Abstract
Comprehensive macro and micro failure analyses of unidirectional and woven graphite/polyimide composites subjected to biaxial shear dominated loading conditions have been performed in this research. The composites have been tested using the biaxial Iosipescu and 10 degrees off-axis tests at room and elevated temperatures. Particular attention has been given to the evaluation of the shear strength properties of graphite/polyimide fabric composites (8 harness satin) as a function the biaxial loading conditions and temperature. Fully non-linear finite element computations of the Iosipescu and 10 degrees off-axis tests have been performed considering the effects of material non-linearity, geometric non-linearity and the effect of specimen sliding within the Iosipescu fixtures. This research resulted in six journal publications and four conference presentations. The abstracts of the journal papers are presented below and the most important findings/accomplishments are briefly described.
