    Abstract

    An analysis of the creep deformation of fiber reinforced metallic composites was developed. Equations for predicting the creep rate and stress-rupture properties of fiber reinforced metallic composites were presented. Stress-rupture and creep tests were conducted at 1200 and 1500 F on tungsten fiber reinforced copper composites. The results of these tests were used to verify the validity of the equations developed in the analysis. A discussion was presented relating the results obtained with the model system to more practical fiber reinforced composite systems for stress-rupture applications. The stress-rupture strengths obtained with the tungsten-copper model system compared favorably with those of existing superalloys and demonstrated the potential of fiber reinforced metallic composites in stress-rupture applications at elevated temperatures.
