Tensile testing machine, also known as material testing machine, is mainly used for testing the mechanical properties of various materials and has important applications in many fields, as follows:
1. metal material field
      Evaluation of material strength: through the tensile test of metal materials, the yield strength, tensile strength and other indicators are measured to determine whether the materials meet the requirements of engineering application. For example, in automobile manufacturing, the strength of the steel used for the body structure needs to be tested by a tensile tester to ensure the safety of the vehicle during driving.
      Research on material ductility: ductility is one of the important characteristics of metal materials. The tensile tester can measure the elongation and reduction of area of metal materials before fracture through tensile test, so as to evaluate the ductility of materials. This has important guiding significance for the selection and optimization of metal processing technology. For example, in metal forging, rolling and other processes, it is necessary to determine the processing parameters according to the ductility of the material to avoid cracks or fractures in the processing process.
2. plastic rubber field
     Determine the mechanical properties of materials: carry out tensile, compression, bending and other tests on plastic and rubber materials to obtain the mechanical property parameters such as tensile strength, elastic modulus and elongation at break. These parameters are very important for the design and production of plastic rubber products. For example, when producing automobile tires, the rubber materials are tested by a tensile tester to ensure that the tires have sufficient strength and elasticity to withstand the effects of various forces during vehicle driving.
     Research on the aging performance of materials: through the long-term tensile test of plastic rubber materials, combined with thermal aging, light aging and other test conditions, study the performance change rule of materials under different environmental factors, and evaluate the service life and reliability of materials. For example, for plastic pipes used outdoors, it is necessary to determine the change of mechanical properties under the conditions of long-term ultraviolet radiation and temperature change through aging test and tensile test, so as to ensure the safe use of pipes.
3. textile fiber field
    Testing fiber strength and elongation: the tensile testing machine can be used to determine the breaking strength, elongation at break and other indicators of textile fibers, and evaluate the quality and performance of fibers. Textiles for different purposes have different requirements for the strength and elongation of fibers. For example, fibers used to make parachutes need to have high strength and appropriate elongation to ensure that they can withstand huge impact force and maintain good toughness during landing.
    Research on fiber elasticity and recovery performance: through repeated tensile and relaxation tests on textile fibers, the tensile tester can study the elasticity and recovery performance of fibers, which is of great significance for evaluating the wrinkle resistance and shape retention of textiles. For example, when developing a new type of elastic fiber, using a tensile tester to study its elastic recovery performance helps to optimize the molecular structure and production process of the fiber, and improve the comfort and durability of textiles.
4. composite material field
    Evaluation of interlaminar bonding strength: for laminated composites, the tensile testing machine can evaluate the interlaminar bonding strength and detect the performance of the composite under interlaminar stress by conducting interlaminar shear test and peel test. For example, in the aerospace field, wing structures made of carbon fiber composites need to pass strict interlaminar bonding strength tests to ensure that there will be no interlaminar separation during flight and ensure the integrity and safety of the structure.
    Research on the comprehensive properties of materials: the tensile testing machine can test various mechanical properties of composites, such as tension, compression, bending, etc., to evaluate the comprehensive properties of composites. Due to the designability of composite materials, testing the composite materials prepared by different formulations and processes by tensile testing machine can provide the basis for the optimization design of composite materials, so as to meet the specific requirements of different engineering applications on material properties.
