Test Background
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.
The tensile test of coated fabrics for membrane structures can be carried out using constant elongation or constant load methods to measure the tensile elongation, tensile delayed deformation and tensile permanent deformation of the coated fabrics.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various coated fabrics and provides professional tensile testing services for coated fabrics used in membrane structures.
Scope of tests
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.
Test method
Stretch the sample at a specified speed to a predetermined elongation value or apply a predetermined load value, and after maintaining the tensile deformation or load for a certain period of time, return to remove the load at the same speed, so that the sample recovers for a certain period of time under zero load, and measure the unrecovered deformation of the sample.
