The invention discloses a lamellar tearing tester for thin-wall flexible materials and a test method thereof, which solve the problems of lack of lamellar tearing testers for thin-wall flexible materials and low measurement result accuracy in the prior art. According to the invention, one end of a rigid supporting shield is connected to an elastic clamp, and the other end is connected to an auxiliary clamping guard board; the elastic clip comprises a plate clip, pressing rods are arranged on the plate clip, the rigid supporting shield comprises an upper shield and a lower shield, the upper shield and the lower shield are symmetrically arranged, the auxiliary clamping shield comprises an upper clamping plate and a lower clamping plate, one end of the upper shield is connected to the upper surface of the plate clip and the other end of the upper shield is connected to the upper clamping plate, one end of the lower shield is connected to the lower surface of the plate clip and the other end of the lower shield is connected to the lower clamping plate, and clamping components are respectively arranged on the upper clamping plate and the lower clamping plate. The tester and the test method disclosed by the invention ensure the stability and accuracy of a test, consequently, test results are reliable, and the precision of measurement is high.
Description
technical field [0001] The invention relates to the technical field of material mechanical performance testing and evaluation, in particular to a thin-walled flexible material delamination tearing test device and a test method thereof. Background technique [0002] In the production and quality control of many thin flexible industrial products such as plastics, rubber, architectural membrane materials, special composite materials and some food materials (vegetable protein extruded textured products), according to the processing of raw materials or finished products Or the stress conditions during use and the relationship between the mechanical properties of the product and the performance of the product, it is necessary to accurately measure and evaluate the interlayer bonding properties such as tear force, tear strength or tear toughness. Although for some specific products or raw materials, such as polymer porous elastic materials, shoe outsoles and microporous sole materi...
