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 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.

Overlap Shear strength was measured on 1" wide x 1/2"

overlap specimen. These bonds were made individually

using 1" x 4" pieces of substrates except for Aluminum.

Two panels 0.063 in. thick, 4 in. x 7y in of 2024T-3 clad

aluminum were bonded and cut into 1 in. wide samples

after 24 hours.

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, 0.125in.; plastics, 0.125 in. The separation rate

of the testing jaws was 0.1 inch per minute for metals

and 2 inches per minute for plastics.
