Summary

SiC monofilament was used to reinforce a modified NZP (sodium zirconium phosphate, NaZr2P3O12) matrix optimized for moderate thermal expansion and high temperature stability. Unidirectional composites containing 23–33 v% SiC filaments were fabricated by filament winding, slurry coating, and hot pressing. The composites were characterized by measuring elastic modulus and matrix-cracking stress in three-point bending and interface sliding friction stress in single-fiber pushout test. The matrix-cracking stress exhibited large variation (50–380 MPa) and was found to correlate with the sliding friction stress. The dependence of the matrix-cracking stress on the interfacial friction stress was compared to theoretical predictions for steady-state cracking for large cracks.
