Mechanical behavior of a microcracked ceramic composite

Conference · · Ceram. Eng. Sci. Proc.; (United States)
OSTI ID:7170720
The mechanical behavior of undirectional composites of Nicalon SiC fibers in a fine-grained Al2O3 matrix, fabricated by colloidal infiltration and pressureless sintering, was examined. The first microcracking of the matrix occurred during cooling from the sintering temperature due to the thermal expansion mismatch between the fibers and the matrix. Determination of the fiber-matrix interfacial frictional stress from the model of Aveston, et al. (1971) and by the indention method of Marshall (1982) are discussed. The load-displacement behavior of these composites in tension was determined. 15 references.
