ASTM D3846 In-Plane Shear Strength of Reinforced Plastics
ASTM D3846 describes the method for determining the inplane shear strength of reinforced plastic composite materials. These specimens are typically thermosetting plastics with reinforcements that widely vary in type and thickness ranging from 2.54 mm to 6.60 mm.
The test method is similar to that of ASTM D695, Test Method for Compressive Properties of Rigid Plastics, except that in the ASTM D3846 method, failure of the specimen occurs in shear between two centrally located notches that are machined halfway through the thickness of the specimen and spaced a fixed distance apart on opposing faces. The same compression fixture is used in both methods and placed between two hardened steel compression platens. Due to the high compressive forces expected, we usually recommend a dual column electromechanical test frame configured with Bluehill® software for this application.
Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Discover simpler and smarter testing with features such as pre-loaded test methods, QuickTest in seconds, enhanced data exporting: and Instron Connect – a new feature that provides a direct communication link to Service. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
