Testing the mechanical properties of materials under bending load is one of the basic methods for testing the mechanical properties of materials. Bending Testing Fixtures with Tensile Testing Machine is mainly used to measure the bending strength of brittle and low plastic materials (such as cast iron, high carbon steel, tool steel, etc.) and can reflect the deflection of plastic indicators. Bending tests can also be used to check the surface quality of materials. The bending test was carried out on the universal material machine. There were two loading modes: three-point bending and four-point bending.
EVA Stripping Fixture detection used as a photovoltaic module packaging EVA, mainly put forward the following performance requirements:
A. Breaking tension strength: the breaking tension strength of EVA after bonding reflects the breaking mechanical strength of EVA after bonding.
B. Fracture elongation rate: the fracture elongation rate of EVA after bonding reflects the extension property of EVA after bonding.
C. Peeling strength of photovoltaic material tensile testing machine: reflects the bonding strength of EVA and glass.
