Aluminum/Kevlar^® Composite In-Plane Crush Properties Testing

Burgett, Chase R.; Bignell, John B.

To determine the in-plane crush properties of a perforated aluminum and Kevlar^® layered composite, confined compression tests were performed. Cylindrical samples were used in the test. The samples were cut by waterjet from bulk material. The tests were conducted in the geomechanics laboratory at Sandia National Laboratories. Force and displacement data were recorded to determine the stress versus volumetric strain up to full compaction of the material. Full compaction was determined to be when the displacement was negligible or when the material had compacted about 63 percent in volume, which was the open volume percent of the aluminum layers in the uncompressed specimens. This testing is intended to capture data for use in the structural models used in support of the certification of the AWG-711 hazardous materials air transportation package.
