Test Background
Shear strength refers to the maximum shear stress that a material can bear under the action of shear stress. The plastic shear test can use a circular perforator to measure the shear strength of the plastic by compression perforation.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various plastics and provides professional shear testing services for plastics and related products.
Scope of tests
Rigid thermoplastics and thermosets, including filled plastics and fiber-reinforced composites.
Thermoset molded sheets, including fillers and reinforcements, thermoset sheets, including laminates, fiber-reinforced thermoset and thermoplastic composites containing unidirectional or non-unidirectional reinforcements such as felt, textile fibers, textile rovings, chopped strand combinations or hybrid reinforcements, twistless rovings and ground fibers, etc.; sheets made of prepreg thermotropic liquid crystal polymers.
Test method
This method uses compression shearing with a circular punch to apply shear load to the sample to cause shear deformation or damage to the sample to measure the shear strength of the material.
Test standard:
HG/T 3839-2006 Plastic shear strength test method Perforation method
GB/T 1039 General principles for testing methods of mechanical properties of plastics
GB/T 2918 Standard environment for conditioning and testing of plastic specimens
