How to test the mechanical properties of expanded graphite. The tensile strength test of expanded graphite includes the tensile strength limit, tensile elastic modulus and elongation of expanded graphite material. The following editor of Furuite Graphite introduces how to test the mechanical properties of expanded graphite:
There are many methods for tensile test of mechanical properties of expanded graphite, such as mechanical measurement, laser speckle, interference and so on. After many tests and analysis, it is found that the tensile strength data can be better obtained through the tensile test of 125 worm graphite. Tensile strength limit refers to the load of large tensile force that the specimen can bear per unit area, and its size is one of the important indexes to comprehensively measure the mechanical properties of expanded graphite materials.
The tensile elastic modulus test can obtain an approximate tensile elastic modulus value through the stress-strain curve obtained from the tensile test of 83 expanded graphite specimens and the rigid secant method. The statistical data of elongation can be obtained by testing 42 expanded graphite specimens.
The expanded graphite produced by Furuite graphite has excellent properties and is widely used. The high-temperature mechanical properties, also called mechanical properties, include compressive strength, compressive elastic modulus, resilience and compression ratio at high temperature for a certain period of time.
