Effects of Weak Interfaces on Thermostructural Behavior of Carbon-Carbon Composites.

Abstract

Continuing research into mechanical and thermal behavior of carbon-carbon composites is described. Results presented include a theory for tensile fracture of yarn-bundles in which the fiber-matrix interface is weak, a minimechanical shear-lag analysis of thermal expansion of 3D carbon-carbons showing that interconstituent slippage has large effects on thermal expansion test data, a discussion of the role of radial yarns during heat treatment of cylindrical 3D billets, and an initial analysis of the effects on constitutive behavior of strain-induced microscale rotations of fibers.
