Summary

The effects of firing temperature and matrix modification on the mechanical and electrical properties of a Nicalon SiC fiber-reinforced ZrP2O7 matrix composite were measured. Firing at 900°C led to improved strength and thermal shock resistance. Matrix modification via a Si3N4 filler led to the formation of macropores and poor thermal shock resistance. Matrix modification via the formation of Zr2P2O9 led to a composite with the best combination of strength, toughness, thermal shock resistance, and electrical properties for use as a composite faceplate in an inexpensive ceramic laminate radome.
