Abstract : A continuation of the dog bone fiber composite study has been focused on the examination of the behavior of these systems containing swollen-end 17-7 PH stainless steel fibers within a work-hardening matrix material and within a superplastic matrix material. Composites were produced in various volume percentages in a eutectoid aluminum-zinc alloy and in pure aluminum. Infiltration of the matrix material about the fibers presented the major barrier in this study. However, centrifugal casting proved to be a satisfactory solution to this problem. Results of tensile tests conducted at room temperature and at 500F showed that the ultimate strength varied directly with fiber density. The stainless steel fibers were found to fail without viscous interaction with the matrix. A discussion of how the strength of dog bone fibers in the composite is limited by geometrical constraints is given. (Author)
