4. Overlap Shear Strength:

The overlap shear strength of 3M™ Scotch-Weld™ Core Splice Adhesive Film

AF 3002 has been determined using the procedures outlined in MMM-A-132A and

under the following conditions.

Metal: 2024T3 Alclad aluminum 4" x 7" x .063".

Cure Cycle: 250°F (121°C) – 50 psi – 60 min. – 10°F/min. warmup.

5. Core Shear Strength:

Core shear strength of Scotch-Weld AF 3002 was determined using a 3" x 8" beam

flexure specimen with a splice made with Scotch-Weld AF 3002 located 2" from

one end of the flexure specimen as shown below:

Face Sheets: 2024T81 bare aluminum, 0.063" thick.

Core shear strength determined according to MIL-A-24563B using the following conditions:

Load Pad: 1.5" single point load.

Reaction Pads: 3/4".

Load Rate: 0.02"/minute.

Span: 6 inches.
