Abstract:

This report summarizes research on characterizing a composite polymeric adherend material and studying, experimentally and theoretically, its reaction in one adhesive joint configuration. The particular material investigated is a continuous fiber graphiteepoxy composite material with a rubber toughened matrix. The composite is nonlinear and viscoelastic at room temperature. A constitutive equation is developed to account for this behavior, and it is then used in a finite element analysis of an adhesive joint. Experimental verifications of the constitutive model and adhesive joint are made. Keywords Composite material, Adhesive joint, Viscoelasticity.
