Glossary of Materials Testing Terms. ASTM C is applicable for continuous bonded surfaces such as foams or discontinuous bonded surfaces such as honeycomb materials. The following determinations can be made from the test results: ASTM C testing determines the flatwise tensile strength of the core, core-to-facing bond, or the facing on an assembled sandwich panel. The data is often used to specify a material, to design parts to withstand application force and as a quality control check of materials.

Touchstone Research Laboratory, Ltd. Formally confirming that your products and services meet all trusted external and internal standards.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Various designs of bonding fixtures, designed to keep the specimen and bonding blocks in alignment while being bonded, are also available. 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.

Permissible core materials include those with a continuous bonding surface balsa wood and foams as well as those with a discontinuous bonding surface honeycomb. The assembly is then pulled apart at the suggested standard head displacement speed of 0. Need help or have a question? Bluehill LE for Basic Testing. By continuing to use our site, you accept our cookie policy. Results from testing can be used to provide information on the strength and quality of core-to-facing bonds.

Historical Version s – view previous versions of standard. 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. Source of Additional Information: Understand ultimate tensile strength and failure of sandwich core materials using thick loading blocks which are bonded to the core or facings.

Validating the specifications, value and safety of your raw materials, products and assets.

Tensile Strength of Sandwich Constructions ASTM C297

Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. One of the aluminum blocks is mounted in a fixture on the stationary side of a universal test machine, while the opposite aluminum block is mounted in a fixture on the moving side of the universal test machine. Failure between an aluminum block and the sandwich structure is not an acceptable failure mode.

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.

Tensile Strength of Sandwich Constructions ASTM C

The standard also permits the use of blocks 1″ in diameter rather than 1″ square, which the fixture can also accommodate. Combining values from the two systems may result in nonconformance with the standard.

The test ASTM C provides information on xstm bonding stability, load transfer and flatwise tensile strength of sandwich core material. Since ASTM Standard C recommends that not less than five specimens be used for acceptance testing, five pairs of steel bonding blocks are supplied with each fixture, as shown in Fig.

How can we help you? It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM C is applicable for continuous bonded surfaces such as foams or discontinuous bonded surfaces such as honeycomb materials. 2c97 request a quote for this test or others Click Here. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Quick release pins are used to attach the bonding blocks to the yokes.

Onsite Training At Your Facility. ASTM C test procedure: Optional mating adapters, if required to attach the fixture to a asrm testing machine, can be provided at nominal cost. Bluehill Universal Software is built from the asmt for touch interaction and an intuitive user experience. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. 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.
