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.

Formally confirming that your products and services v297 all trusted external and internal standards. Validating the specifications, value and safety of your raw materials, products and assets.
Flatwise Tensile Strength of Sandwich Constructions ASTM C
Elevated or reduced temperature test procedure: WaveMatrix 2 for Dynamic Testing. ASTM C is asstm for continuous bonded surfaces such as foams or discontinuous bonded surfaces such as honeycomb materials. The standard Wyoming fixture shown utilizes bonding blocks 1″ square in cross section, the minimum size recommended in ASTM Standard C For discontinuous cellular bonded surfaces, specimen geometry is base on cell size.
Email addresses can only contain letters, numbers and the following special characters: Properties that may be derived from this test method include flatwise tensile strength. 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.
ASTM C test procedure: The force is transmitted to the sandwich through loading blocks that are bonded to the surface facings or to the core. 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.

Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more! If the bond between core and substrate is sufficiently strong then strength of the core material can be determined.
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. It can also be used to produce astmm tensile strength data for the core material. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Any number of additional blocks, or alternate materials such as aluminum, can be provided upon request. To request a quote for this test or others Click Here.
Standards can be obtained from appropriate standards authorities. The chamber is designed to allow astj test mounts from the base and crosshead of the test machine to pass through the top and bottom c279 the chamber.
Test specimens are cut from sandwich panels, and the faces of the test specimens are bonded to aluminum blocks. Bluehill Universal Brochure Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Bluehill LE for Basic Testing. 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.
Combining values from the two systems may result in nonconformance with the standard.
The fixture, shown in Fig. Certification Formally confirming that your products and services meet all trusted external and internal standards.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. 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 the life of the blocks. A sandwich construction is subjected to a uniaxial tensile force normal to the plane of the sandwich.
Source of Additional Information: Standard test fixtures are installed inside the chamber, and testing is conducted inside the controlled thermal environment the same as it would be at ambient temperature.
