Abstract
This study sought to characterize the performance and failure characteristics of a hybrid composite material created by the insertion of 301 stainless steel foils in a composite layup composed of IM7/977-3 preimpregnated unidirectional carbon fiber. The hybrid layup was adapted from a conventional composite layup, and the two are compared through this study in 9-ply and 18-ply configurations. The hybrid composite demonstrated a marked increase in bearing load capacity with an ultimate bearing load improvement of 42% in the 9-ply case. Methods, results, and analysis of Nondestructive Investigation (NDI) and bearing testing are presented. Micrographs of sectioned progressive failure samples are presented, which correlate to specific phenomena in the given stress strain curves.
