ASTM C297 PDF

ASTM C describes a method of determining the bond strength between the facing and core of a sandwich core panel or the strength of the core itself, if the. ASTM D – Air Permeability of Textile Fabrics . ASTM C testing determines the flatwise tensile strength of the core, core-to-facing bond, or the facing on. ASTM C is a testing specification that determines the flatwise tensile strength of the core, the core-to-facing bond, or the facing of an assembled sandwich.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: 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.

Optional mating adapters, if required to attach the fixture to a specific testing machine, can be provided at nominal cost. The asfm has internal electric heaters for elevated temperatures and uses external carbon dioxide gas as a coolant for reduced temperatures. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Software for Series Systems.

Tensile Strength Composite Sandwich Constructions

ASTM C testing determines the flatwise tensile strength of the core, core-to-facing bond, or the facing on an assembled sandwich panel. One type of bonding fixture is shown in Fig.

While it is primarily used as a quality control test for bonded sandwich panels, it can also be used to produce flatwise tensile strength data for structural design properties, material specifications, and research and development applications. Properties that may be derived from this test method include flatwise tensile strength. Understand ultimate tensile strength and failure of sandwich core materials using thick loading blocks which are bonded to the core or facings.

One of the aluminum blocks is mounted in a fixture on the stationary side of a universal test machine, while the opposite aluminum atsm is mounted in a fixture on the moving side of the universal test machine. Touchstone Research Laboratory, Ltd.

The assembly is then pulled apart at the suggested standard head displacement speed of 0. Contact Us View Accessories Catalog.

Select from list below: Elevated or Reduced Temperature Test Procedure: A sandwich construction is subjected to a uniaxial tensile force normal to the plane of the sandwich. The following determinations can be made from the test results:. The chamber is designed to allow the test mounts from the base and crosshead of the test machine to pass through the top and bottom of the chamber. Send us a request Need help or have a question?

Various designs of bonding fixtures, designed to keep the specimen and bonding blocks in alignment while being bonded, are also available.

Wyoming Test Fixtures Inc. Glossary of Materials Testing C97. Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb.

If the bond between core and substrate is sufficiently strong then strength of the core material can be determined. The bonding blocks have 1″ square ends, and are designed so that either end of each block can be used as the bonding surface, thus doubling v297 life of the blocks. Test specimens are cut from sandwich panels, and the faces of the test specimens are bonded to aluminum blocks.
