Abstract

Rubber-to-metal bonds are important in a variety of automotive, tire, and marine applications. Rational approaches to design for long term integrity may require accurate determination of the fracture toughness of these bonds during exposure to corrosive environments. Several new techniques are discussed for measuring fracture toughness, and observations are offered for conducting these tests.

Keywords:
fracture toughness, elastomers, rubber, adhesive bonds, blister test, double cantilever beam, corrosive environments
