ASTM C297 Standard Test Method for Flatwise Tensile Strength of Sandwich Constructions

Scope: 
This test is designed to test for bonding stability, load transfer, and flatwise tensile strength of sandwich core material.  This test is applicable to continuously bonded surfaces or discontinuous surfaces such as a honeycomb material.

Procedure: 
The specimen is prepared by bonding both faces to metallic blocks that can be fit to the tension fixtures by means of a pin, thus creating a universal joint.  The blocks are then pulled apart at the testing speed designated in the standard until rupture while. 

Data:
Tensile strength and strain, modulus of elasticity, failure location, and failure mode

Equipment Used:
Test frame, aluminum blocks and fixtures
