ASTM D is a testing standard designed to measure the shear properties of composite materials. Beam Method, or more commonly known as the Iosipescu Shear Method, was standardized into ASTM D in , while the V-Notched Rail Shear Method . ASTM D TESTING FIXTURE. SHEAR PROPERTIES OF COMPOSITE MATERIALS BY THE V-NOTCHED BEAM METHOD. 1. ASTM D Testing Fixture.

A special fixture is used to hold the coupon and load is applied at a specified rate until failure occurs. Touchstone has extensive experience in utilizing different coupon geometries, the use of different tab materials and adhesives, and proper preparation of notches, all of which are critical to ensure accurate results.

A notched beam specimen is placed in a shear fixture. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Properties, in the test direction, which may be obtained from this ashm method, include the following:.
The data can be used for research and development purposes concerning interply strength or composite material comparison. The sample preparation, including notching, can atsm done at your facility or by Touchstone. Combining values from the two systems may result in non-conformance with the standard.
The test specimens are 76 x 11 mm at composite thickness with a V notch above and below the 11mm dimension. A load is applied at a specified rate until specimen failure occurs.
