Tensile Strength Composite Sandwich Constructions
Flatwise tensile strength of sandwich construction is a measure of the strength between the substrate and the core material. If the bond between core and substrate is sufficiently strong then strength of the core material can be determined.
To meet the requirements of ASTM C297, we offer a range of fixtures for this type of testing. A variety of materials including aerospace grade, honeycomb core, continuous core, and organic or metallic core materials can be adhered to various sizes of specimen blocks which are placed onto dual yoke fixtures and loaded axially via an Instron testing machine at a constant rate.
The test results can be analysed using Instron® Bluehill® Software.
The following Instron fixtures conform to ASTM C297.
For a shear fixture conforming to ASTM C273 see S4681A and S4682A.
The sandwich flatwise tension fixture is designed to measure the bond strength between the facing and core of a sandwich construction panel.
