Description

technical field [0001] The invention belongs to the field of tensile test equipment, in particular to a four-way or two-way tensile test equipment for polymer materials. Background technique [0002] In recent years, polymer functional materials have been widely used in aerospace, shipbuilding, energy storage, electronic devices, building materials, biomedical, agricultural and other fields. However, in order to meet the use requirements in increasingly complex and harsh environments, the properties of polymer materials, especially the mechanical properties, often fail to meet the use requirements. Therefore, how to control the molecular chain orientation distribution and topological entanglement structure of polymer materials has become the main problem in the design and preparation of high-performance polymer materials. [0003] Biaxially stretched polymer materials are isotropic and have excellent mechanical properties in all directions. Biaxially stretched polypropylene...
