ASTM C Compression Sandwich Core Flatwise Test Machine
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The results of ASTM C, flatwise compressive strength and modulus, are fundamental mechanical properties of sandwich cores that are used in the design of sandwich panels.
These mechanical properties can, in turn, be used in design purposes, material specifications, research and development applications and quality assurance. As the voice of the U. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. This standard is not included in any packages.
Flatwise Compressive Properties by ASTM C365
These material properties are ashm for the design purposes in a direction normal to the plane of facings as the core would be placed in a structural sandwich construction. The test procedures pertain to compression in this asfm in particular, but also can be applied with possible minor variations to determining compressive properties in other directions.

Assurance Testing Inspection Certification. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Deformation data can be obtained, and from a complete force versus deformation curve, it is possible to compute the compressive stress at any applied force such as compressive stress at proportional limit force or compressive strength at the maximum force and to compute the effective modulus of the core.
Already Subscribed to this document. Information gained from ASTM C is often applied to design processes, materials specs, research and development, and quality assurance. Standards can be obtained from appropriate standard authorities. It is customary aerospace industry practice to determine compression modulus only when using stabilized specimens. ASTM C testing covers the determination of compressive strength and modulus of sandwich cores. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
Standards Subsctiption may be the perfect solution. Continuous bonding surfaces — minimum facing area shall be mm 2 1. These properties are usually determined for design purposes in a direction normal to the plane of facings as the core would be placed in a structural sandwich construction. The test method investigates how the core materials, methods of fabrication, core geometry, core density, loading process, and the loading process affects the compressive strength of the honeycomb material.
Flatwise compressive strength data may be generated using either stabilized specimens reported as stabilized compression strength or non-stabilized specimens reported as bare compression strength. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Core materials applicable include continuous foams and discontinue bonding surfaces honeycomb — stabilized or unstabilized. Proceed to Checkout Continue Shopping. This measures the deflection of the specimen and is used to calculate strain throughout the test. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
