Download PDF 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 …
Download PDF This test method indicates the compression properties of strength and stiffness of composite materials with polymer matrix by means of a combined compression load. This type of testing can be applied to general composites that are balanced and symmetric. The specimen may be untabbed (Procedure A) or tabbed …
Download PDF 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 …
Download PDF It can be provided platens of all types, in all sizes and load capacities, and also custom designs for special applications. Platens of 6″ diameter are the most popular size. Typically, platens are fabricated of fully through-heat-treated 440C stainless steel, characterized by high surface hardness and durability in …

Download PDF This test method has the purpose of determining the mechanical properties of unreinforced and reinforced rigid plastics, including high-modulus composites, when loaded in compression at relatively low uniform rates of straining or loading. The test specimens employed are characterized of a standard shape. This fixture is used in order to …
