Overlap shear (OLS) strengths were measured on 1 in. wide 1/2 in. overlap specimens. These
bonds were made individually using 1 in. x 4 in. pieces of substrate except for aluminum. Two
panels 0.063 in. thick, 4 in. x 7 in. of 2024T-3 clad aluminum were bonded and cut into 1 in.
wide samples after 24 hours. The thickness of the bondline was 0.005-0.008 in. All strengths
were measured at 73°F (23°C) except where noted.
The separation rate of the testing jaws was 0.1 in. per minute for metals, 2 in. per minute for
plastics and 20 in. per minute for rubbers. The thickness of the substrates were: steel, 0.060 in.;
other metals, 0.05-0.064 in.; rubbers, 0.125 in.; plastics, 0.125 in.
T-peel strengths were measured on 1 in. wide bonds at 73°F (23°C). The testing jaw separation
rate was 20 inches per minute. The substrates were 0.032 in. thick.
Bell peel strengths were measured on 1/2 in. wide bonds at the temperatures noted. The testing
jaw separation rate was 6 in. per minute. The bonds are made with 0.064 in. bonded to 0.025 in.
thick adherends.
With the exception of Rate of Strength Build-Up Tests, all bonds, were cured 7 days at 73°F
(23°C) at 50% RH before testing or subjected to further conditioning or environmental aging.
