Plastic mechanical properties testing


The test of mechanical properties of plastics is also called mechanical property test. It refers to a series of mechanical properties of materials exhibited by materials under normal temperature/high temperature/low temperature and static load. It reflects the ability of materials to resist deformation or damage under external force. Identify important basis for material design parameters in engineering applications.


The mechanical properties test needs to be tested in accordance with the requirements of the test method and test standard in the specified environment under the specified environment. The mechanical properties of the finished product can be simulated according to the customer's requirements. Perform mechanical properties testing.


Common mechanical properties are tested:


• Tensile properties (normal temperature stretching, high temperature stretching, low temperature stretching):


Tensile strength, elongation at break, modulus of elasticity, yield strength, Poisson's ratio


• Bending performance


Bending strength, flexural modulus


• Compression performance


Compressive strength, compressive strain, compressive modulus, permanent compression set


• Impact strength (normal temperature impact, low temperature impact)


Cantilever beam impact, simply supported beam impact, drop hammer/ball impact, dart impact


• Tear strength


Right angle tear, pants tear, crescent tear

• Hardness test

Rockwell/Rockwell-α hardness, Shore hardness, Barcol hardness, micro Vickers hardness

•Shear strength

Interlaminar shear, longitudinal and transverse shear, stamped shear, tensile shear

• Friction wear

Sliding friction, Taber wear, dynamic / static friction coefficient

•stress test


Pull-pull fatigue test, fast prediction method of life, dynamic fatigue (lifetime)


• Creep test


Tensile creep, compression creep
