Effect of the coating properties on crack propagation in fiber-reinforced materials
- Univ. of Cincinnati, OH (United States)
A finite element technique is used to study the effects of the coating properties on the crack propagation in fiber-reinforced materials. Crack opening stresses and energy release rates for the crack penetration and deflection have been studied in SCS6 (fiber) -C/BN (coating) - Zircon (matrix) composites. Effect of the coating thickness on crack propagation has been also studied. In general, no significant changes are found in stress ratio (ratio of hoop stresses along the crack and at the interface) and energy release rate ratio (ratio of energy release rates for the crack penetration and crack deflection), but the magnitudes of the stresses and energy release rates change substantially with the change in the coating thickness.
