This paper deals with the strength and failure prediction as well as the reliability issues of adhesive joints of brittle epoxy bonding two dissimilar adherends. The effects of bond thickness and scarf angle upon the strength of such joints are also addressed. Three kinds of adhesive joints, i.e., butt, scarf and shear joints are considered. It is found that the strength prediction of various adhesive joints can be done by establishing the interface corner toughness, Hc parameter. Weibull modulus is suitable to define the reliability of adhesive joints. The scarf joint of 45° is identified to be preferable since it satisfies both outstanding load-bearing performance and tolerable reliability. Hence, both applications of Hc parameter and Weibull statistical method allow the strength and failure predictions of adhesive joints with fairly improved reliability.
