Functionally Graded Adhesives

Abstract

The goal of this project was to increase rubber to metal adhesion in Army materials using the concept of functionally graded interfaces as observed in squid beaks. Through application of adhesive as a graded interface with layers of varying rigidity, exceptional adhesion can be accomplished. 3M Scotch-Weld 847 was chosen as the adhesive because of its flexibility, potential for use on Army weapons platforms, and because it contains no hazardous air pollutants. Talc, silica, and calcium carbonate fillers at various loading levels were added to increase the rigidity of the adhesive. Various methods were employed to optimize the dispersion of the filler in the adhesive. Testing with 5, 10, and 12.5 lb loads, as well as, Instron instrumental testing illustrated that a graded interface at various percentages provides superior adhesion than a non-graded system or the neat baseline adhesive.
