Comparison of Structural Behavior of Superplastically Formed/Diffusion-Bonded Sandwich Structures and Honeycomb Core Sandwich Structures.

Abstract

This paper discusses a new superplastically formed/diffusion-bonded (SPF/DB) orthogonally corrugated core sandwich structure and compares its structural behavior with that of a conventional honeycomb core sandwich structure. The stiffness and buckling characteristics of the two types of sandwich structures are compared under conditions of equal structural density. Under certain conditions, the SPF/DB orthogonally corrugated core sandwich structure is slightly more efficient than the optimum honeycomb core (square-cell core) sandwich structure. However, under different conditions, this effect can be reversed. (MM)
