Summary

Composites reinforced with Sic whisker plus Sic particulates have been prepared by infiltration with molten SrSiO, and with molten SrO-Al2O3 2SiO2 using a technique1previously described. The measured properties of these composites include MOR in the as-fabricated state and after high temperature oxidation exposure, fracture toughness (based on DPH observations), and thermal shock resistance. SEM micrography of fracture surfaces indicates that limited pullout may be contributing to fracture toughness. These properties suggest the applicability of such whisker/particulate composites as matrices for continuous filament reinforcement.
