The fixture is used for testing composite materials under uniaxial compression. The flat piece is a load plate made of hardened steel, to be interposed between the upper protrusion of the specimen and the load floor of the test machine, to protect the load plate. There is actually no ASTM standard governing the Modified D 695 Compression Test Method. ASTM…
This method defines the compression properties in the plane of composite materials with polymer matrix reinforced with high modulus fibers. The composite material forms are limited to continuous or discontinuous fiber-reinforced composites. For this reason, the elastic properties are particularly orthotropic with respect to the test direction. This test procedure inserts the compression force in the sample by cutting the…
