B. Aluminum T-Peel

T-Peel bonds were measured on 1 in. wide specimens cut from two FPL etched 8 in.

x 8 in. x .032 in., 2024 T3 clad aluminum panels bonded together. The separation

note of the testing jaws was 20 in./minute. Tests similar to ASTM D-1876.

C. Overlap shear on abraded metals, plastics, and rubber

Overlap shear 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.

The thickness of the substrates were: cold rolled, galvanized and stainless steel –

0.056-0.062 in., copper – 0.032 in., brass – 0.036 in., rubbers – 0.125 in., plastics –

0.125 in. All surfaces were prepared by solvent wiping/abrading/solvent wiping.

The jaw separation rate used for testing was 0.1 in. per minute for metals, 2 in. per

minute for plastics, and 20 in. per minute for rubbers.
