Sandwich Flexural Stiffness by ASTM D7249

Core materials applicable include continuous foams and discontinuous bonding surfaces honeycomb. Active view current version of standard. Due to the curvature of the flexural test specimen when loaded, facesheet compression strength from this test may not be equivalent to the facesheet compression strength of sandwich structures subjected to pure edgewise in-plane compression.

Specimens are conditioned if required. Four point flexure of flat sandwich constructions to produce curvature of the sandwich facing plane.

Combining values from the two systems may result in non-conformance with the standard.
