The test fixture is designed to provide a combined loading to the unsupported center 12 mm 0. This type of testing can be applied to general composites that are balanced and symmetric.
This test method is designed ashm produce compressive property data for material specifications, research and development, quality assurance, and structural design and analysis. The specimen is compressed to failure.
When testing lower strength materials such that untabbed CLC specimens can be used Procedure Athe benefits of combined loading become particularly prominent. When a material has a high compressive strength in the direction of loading, end crushing may occur. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D A gage length between 12 mm and 25 mm [1.
ASTM D6641 Compression Testing for Polymer Matrix Composite Laminates
Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries. This test method determines compressive properties of polymer composite materials by applying combined end-loading and shear-loading using a combined loading compression CLC fixture.
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.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
The test fixture is designed to provide a combined loading to the unsupported center 12 mm 0. For high orthotropic materials, such as unidirectional composites, tabs are requested.
Due to the very large number of tests offered, descriptions of those most astj requested have been gathered into the following groups:.
Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2.
Intertek PTL – Compressive Properties of Polymer Matrix Composite Laminates ASTM D
A universal testing machine can be used to test the untabbed, straightsided composite specimen of a rectangular cross section. This test method determines compressive properties of polymer composite materials by applying combined end-loading and shear-loading using a combined loading compression CLC fixture.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. You may also consider looking into a loading compression fixture and an environmental chamber if needed. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
Standards can be obtained from appropriate standards authorities. Failure to carefully prep your sample can result in premature end-crushing of the specimen during loading, excessive induced bending or buckling, and even invalidation of your test.
It is important to remember that the ends of the test sample should be parallel to each other and perpendicular to the long axis of the coupon. The fixture is placed between the platens of a Universal Testing Machine, and if a strain measuring device is being used, it is attached to the specimen.
The test specimen is inserted into the two halves of the test fixture so that the ends of the specimen are flush with the top and bottom of the test fixture, and the bolts in the fixture are tightened to a specified torque to capture the test specimen.
The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Specimens should have a uniform rectangular cross section, 12 mm 0.
This test method indicates the compression properties of strength and stiffness of composite materials with polymer matrix by means of a combined compression load.

The specimen may be e6641 Procedure A or tabbed Procedure Bas required. This test method is applicable to general composites that are balanced qstm symmetric. By means of our testing expertise and modular product design, we will help find the testing solution that is right for you.
ASTM D TESTING FIXTURE
C6641 standard does not purport to address all of the safety concerns, if any, associated with its use. The test specimen is inserted into the two halves of the test fixture so that the ends of the specimen are astn with the top and bottom of the test fixture, and the bolts in the fixture are tightened to a specified torque to capture the test specimen.
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 D is applicable to general flat laminates that are balanced and symmetric and contain at least one 0 percent ply.
