# ASTM C363

Standard Test Method for Node Tensile Strength of Honeycomb Core Materials

[Back to all techniques](/analytical-techniques/)

## Significance and Use

5.1 The honeycomb tensile-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 tensile-node bond strength is the tensile stress that causes failure of the honeycomb by rupture of the bond between the nodes. It is usually a peeling-type failure.

5.2 This test method provides a standard method of obtaining tensile-node bond strength data for quality control, acceptance specification testing, and research and development.

## Scope

1.1 This test method covers the determination of the tensile-node bond strength of honeycomb core materials.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
