ASTM D6641 Combined Loading Compression Fixture – Composite Laminates | GD6641-705
Validating the specifications, value and safety asmt your raw materials, products and assets. ASTM D establishes a procedure for measuring the compressive strength and stiffness properties of polymer matrix composite materials using a combined loading compression CLC or comparable test d6614. One requirement for a successful test is that the specimen ends do not crush during the test. Combining values from the two systems may result in nonconformance with the standard. Materials of higher orthotropy, including unidirectional composites, typically require tabs.
The compressive force is introduced into the specimen by combined end- and shear-loading. One of the basic rules is that the ends of d641 specimen does not crush during the test. You may also consider looking into a loading compression fixture and an environmental chamber if needed. This standard does not purport to address all of the safety concerns, if any, associated with its use.

Touchstone Engineers are experienced in specimen preparation d66641 tabbing, which may be vital in D testing to ensure accurate results.
This test method indicates the compression properties of strength and stiffness of composite materials with polymer matrix by means of a combined compression asm.
This type of testing can be applied aztm general composites that are balanced and symmetric. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Within the test the inch-pound units are shown in brackets.
If the fixture clamping forces do induce significant stress concentrations at the ends of the gage section, tabbing is required for the material in order to increase the load-bearing area at the specimen ends.
The specimen may be untabbed Procedure A or tabbed Procedure Bas required.
Composite properties in the test direction that may be obtained from this test method include: It may not be possible to successfully test untabbed specimens of these same materials using either of the other two methods.
Due to copyright restrictions, we are not able to provide copies of standards. Testing samples should be around mm [5.
The specimen is compressed to failure.

Have a question about conducting the test for this standard? For high orthotropic materials, such as unidirectional composites, tabs are requested. The test fixture is designed to provide a combined loading to the unsupported center 12 mm 0. A gage length between 12 mm and 25 mm [1.
This test method is atm to produce compressive property data for material specifications, research and development, quality assurance, and structural design and analysis. The fixture clamping forces induced by the applied bolt torques required to successfully fail the composite before specimen end crushing must not induce significant stress concentrations at the ends of the gage section of the specimen.
