Abstract

Abstract: The impact shear strength of phenolic resin adhesive blended with nitrile rubber in a double-lap steel joint was measured to discuss the applicability of the strain rate-temperature equivalent principle. This strain rate-temperature equivalent principle was confirmed to be applicable to the quasi-static shear strengths of the adhesive. Because phenolic resin adhesive blended with nitrile rubber was in the glass transition state under a quasi-static deformation at room temperature and its adhesive strength was sensitive to the strain rate, the impact strength of the adhesive could not be predicted without the strain rate-temperature equivalent principle. Instead, the impact strength of the adhesive measured by using a manufactured impact testing machine could be predicted approximately with quasi-static results at low temperature by using the principle. The strain rate-temperature equivalent principle was clarified to be sufficient for predicting impact strengths without the need for impact testing.
