Summary:

ASTM C297 is in Touchstone’s NADCAP and ISO 17025 scope.

ZONHOW ASTM C297 with 2 inches Flatwise Tensile Strength fixture determines the flatwise tensile strength of the core, core-to-facing bond, or the facing on an assembled sandwich panel. Permissible core materials include those with a continuous bonding surface (balsa wood and foams) as well as those with a discontinuous bonding surface (honeycomb).

A sandwich construction is subjected to a uniaxial tensile force normal to the plane of the sandwich. The force is transmitted to the sandwich through loading blocks that are bonded to the surface facings or to the core.

Core-to-facing bond integrity is necessary to maintain facing stability and permit load transfer between the facings and the core. Results from testing can be used to provide information on the strength and quality of core-to-facing bonds. Results may also provide information on flatwise tensile strength data of the core material.
