ASTM D3410 / D3410M – 16 : Standard Test Method for Compressive Properties of Polymer Matrix Composite Materials with Unsupported Gage Section by Shear Loading
This test method determines the in-plane compressive properties of polymer matrix composite materials reinforced by high-modulus fibers.
The composite material forms are limited to continuous-fiber or discontinuous-fiber reinforced composites for which the elastic properties are specially orthotropic with respect to the test direction.
This test procedure introduces the compressive force into the specimen through shear at wedge grip interfaces.
This type of force transfer differs from the procedure in Test Method where compressive force is transmitted into the specimen by end-loading, Test Method where compressive force is transmitted by combined shear and end loading, and Test Method where compressive force is transmitted by subjecting a honeycomb core sandwich beam with thin skins to four-point bending.
