Evaluation of interfacial frictional properties for fiber-reinforced ceramic composites
- Alcoa Laboratories, Alcoa Center, PA (USA)
An analytical model is developed to determine the frictional properties of the fiber-matrix interface in ceramic matrix composites using the indentation test. This mdoel includes the effect of the interfacial friction stress arising from the transverse expansion of the fiber subjected to the compressive load. Two intrinsic interfacial properties, an interfacial friction limit and an interfacial coefficient of friction, are determined for a SiC fiber-reinforced lithium aluminosilicate glass-ceramic matrix composite. It is found that, during the indentation test, the interfacial friction coefficient is more pronounced at lower values of applied load. As the load increases, the behavior is dominated by the interfacial friction limit. 9 refs.
