ABSTRACT:
The adhesion of cord or wire to the elastomer, rubber, or rubbery material is measured by exerting forces or loads collinear with the cords or wires such that one of the cords or wires is pulled from between a pair of cords. The three cords are embedded in a predetermined length of the elastomer. In a static test the opposing forces are exerted at a predetermined rate. In a dynamic test the opposing forces oscillate at predetermined frequency. Fixtures adapting an MTS high-speed oscillating tester are provided. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
