WebA modified lap-shear method was used to evaluate the bond strength of the elastomers with various adhesives. For each assembly, two elastomer pieces measuring 1 * 1 * 0.125 in. were bonded together with a 0.25-in. overlap, yielding a bond area of 0.25 sq in. The elastomer pieces were bonded to steel lap shears to provide additional rigidity in ...
