Strength test of coated fabric joints for membrane structures

Coated fabrics for membrane structures refer to synthetic fiber or glass fiber fabrics as base fabrics, which are covered with a polymer continuous layer on the surface of the base fabrics through impregnation, coating or lamination processes, and are used as coated fabrics for membrane structure construction. Joint strength refers to the maximum force that a membrane material containing joints can stretch until the joints break under specified conditions. The joint strength test of coated fabrics used in membrane structures can determine the strength properties of the joints.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various coated fabrics and provides professional joint strength testing services for coated fabrics used in membrane structures.

PA coating, PU coating, anti-velvet coating, PA white glue coating, PU white glue coating, PA silver glue coating, PU silver glue coating, pearlescent coating, flame retardant coating, etc.

1. Clamp the specimen containing joints on the clamp of the tensile tester, and stretch the specimen at a specified rate (the stretching direction is perpendicular to the joints) until the joints of the specimen break under the action of the tensile force.
2. There are mainly three situations of fracture:
a) Membrane material breaks;
b) The connector is broken;
c) A combination of the two above.
