EFFECT OF BOND VOIDS ON FATIGUE STRENGTH

Abstract

Axial tension-tension fatigue tests were made with adhesive bonded aluminum alloy honeycomb panels comprised of 2024 aluminum alloy face plates, Specification MIL-C-7438B honeycomb core and Minnesota Mining and Manufacturing Co., EC 1469 adhesive. Voids of various sizes were introduced into the test specimens to permit study of their effect on fatigue strengths. Bond endurance was found to depend on bond perimeter as well as area; longer perimeters with a given area produce longer life within limits. Voids were not found to expand or propagate under repeated loads.
