Standard and method of testing for plastic tensile testing machine

According to user requirements, the maximum strength, elastic modulus (E), constant compressive strength, constant load elongation, yield strength, etc. of non-metallic materials can be obtained. Yield strength, non-proportional strength, total compressive strength, compressive (pulling) strength, elongation, etc. of metallic materials.
Plastic tensile testing machine test standard: GB/T 9341-2000

The bending test is mainly used to test the performance of materials when subjected to bending load. The bending test is commonly used in production to evaluate the bending strength and plastic deformation of materials. It is an important reference index for quality control and application design.

The national standard GB/T 9341-2000 describes the steps of the test in detail.

This section applies to:

Thermoplastic molded and extruded materials, including filled and reinforced unfilled materials and rigid thermoplastic sheets. These properties include flexural strength and flexural modulus of elasticity.

Thermoset molded sheets, including filled and reinforced materials, thermoset sheets, including laminates

Fiber reinforced thermosetting and thermoplastic composites containing unidirectional or non-unidirectional reinforcing materials such as felt textile fiber woven roving chopped strands or hybrid reinforced rovings and ground fibers; made of prepreg Sheet thermotropic liquid crystal polymer

Plastic tensile testing machine configuration:

Sample preparation instrument: using the sample preparation mechanism to obtain a number of standard samples

Test machine host: HY-0580 desktop electronic universal testing machine

Test equipment accessories: Plastic tensile testing machine can evaluate rigid and semi-rigid materials using three-point bending loading

At the same time, the support span (size) of the sample is related to the thickness of the sample, so it is important to know the size range of the sample before selecting the fixture. The size of the loaded indenter and base is different for different standards. Please refer to the standard for the balance wing tester.

Linear encoder or resistance strain gauge: When performing a three-point bending test, it is not suitable to measure the deflection using the displacement of the beam. Therefore, in the three-point bending test, a linear scale or a resistance strain gauge is used to directly measure the twist and strain.
