Analysis of Stress-Rupture and Creep Properties of Tungsten Fiber Reinforced Copper Composites

Source

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.
