Four-way or two-way tensile test equipment for polymer materials

Abstract

The invention discloses a four-way or two-way tensile test equipment for polymer materials. A four-way or two-way tensile test equipment for polymer materials, including a first clamping mechanism, a second clamping mechanism, a third clamping mechanism, and a fourth clamping mechanism; the first clamping mechanism and the second clamping mechanism The first horizontal driving mechanism is connected, the third clamping mechanism and the fourth clamping mechanism are connected with the second horizontal driving mechanism; it also includes a box body with a sealed door, a temperature control system and a light source are arranged in the box body, and a There is a ventilation system; the first clamping mechanism, the second clamping mechanism, the third clamping mechanism and the fourth clamping mechanism are all located in the box. The test device integrates all components in the box, and can set the test conditions such as temperature, light, gas, etc. in the box to meet the test requirements of various film stretching, and can realize user-defined external field conditions and stretching. The preparation and mechanical property testing of the polymer thin film material of the method have a wide range of applications.

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...
