The honeycomb node bond strength is a fundamental property than can be used in determining whether honeycomb cores can be handled during cutting, machining and forming without the nodes breaking. The node bond strength is the tensile load that causes failure of the honeycomb by rupture of the bond between the nodes. It is usually a peeling-type failure.
This test method provides a standard method of obtaining honeycomb core node strength data for quality control, acceptance specification testing, and research and development.
1.1 This test method covers the determination of the delamination strength (node bond strength) of honeycomb core materials.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given may be approximate.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
