ASTM C297 – Flatwise Tensile Strength of Sandwich Constructions
Since the physical properties of many materials can vary depending on temperature, it is sometimes appropriate to test materials at temperatures that simulate the intended end use environment. Failure between an aluminum block and the sandwich structure is not an acceptable failure mode.
Historical Version s – view cc297 versions of standard. The chamber has internal electric heaters for elevated temperatures and uses external carbon dioxide gas as a coolant for reduced temperatures.
The test ASTM C provides information on core-to-face bonding stability, load transfer and flatwise tensile strength of sandwich core material. Email addresses must contain the symbol. A through-the-thickness flatwise tensile test of a sandwich panel is performed.
Flatwise Tensile Strength of Sandwich Constructions ASTM C
The adhesive must then be allowed the appropriate conditioning before testing. Properties that may be derived from this test method include flatwise tensile strength. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

WaveMatrix 2 for Dynamic Testing. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. Since the physical properties of many materials can vary depending on temperature, it is sometimes appropriate to test materials at temperatures that simulate the intended end use environment.
The values astj in each system are not exact equivalents; therefore, each system must be used independently of the other. ASTM C test procedure: If the bond between core and substrate is sufficiently strong then strength of the core material can be determined.
Flatwise Tensile Strength of Sandwich Constructions ASTM C297
Various designs of bonding fixtures, designed to keep the specimen and bonding blocks in alignment while being bonded, are also c97. Glossary of Materials Testing Terms.
Source of Additional Information: The following determinations can be made from the test results: The assembly is then pulled apart at the suggested standard head displacement speed of 0.
Quick release pins are used to attach the bonding blocks to the yokes. Core-to-facing bond integrity is necessary to maintain facing stability and permit load transfer between the facings and the core. Description Literature Contact Us Flatwise tensile strength of sandwich construction is a measure of the strength between the substrate and the core material.

Results from testing can be used to provide information on the strength and quality of core-to-facing bonds. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well axtm those with discontinuous bonding surfaces such as honeycomb.
Email asgm can only contain letters, numbers and the following special characters: The adhesive must then be allowed the appropriate conditioning before testing. For continuous bonded surfaces, the minimum facing size is mm2 1. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Tensile Strength of Sandwich Constructions ASTM C Understand ultimate tensile strength and failure of sandwich core materials using thick loading blocks which are bonded to the core or facings.
