Dulabilities of Stressed Adhesive Lap Joints of Stainless Steel Plates under the High Humidity Conditions

Abstract

The lifetimes of stressed lap joints of stainless steel plates (1.5mm thickness) bonded by one-liquid type and two-liquid type epoxy adhesives,the gradient of stress-life time curve increasing with decreasing life time of 5.5 MPa which is high stress range. The other side, life time of two-liquid type adhesives is shorter than that of one-liquid ones in the high stress range, but in the low stress range life time of former ones is larger than that of latter ones.
