The invention discloses a clamp for testing a tensile property of a lightweight thin material. The clamp comprises a first clamping part, a second clamping part and a fastening device, wherein the first clamping part and the second clamping part are connected through the fastening device; a groove is arranged on the first clamping part; a bulge which is matched with the groove is arranged in the position on the second clamping part corresponding to the first clamping part; the groove is U-shaped; and a friction pad is arranged between the groove and the bulge. A U-shaped structure is utilized by the clamp provided by the invention to increase a clamping resistance; a rubber pad is utilized to increase a frictional resistance; a bolt connection mode is utilized to clamp a braided fabric and prevent the braided fabric from skidding during the process of testing the tensile property of a high-strength material; and a frictional force between a tested material and the clamp is increased by the clamp provided by the invention when the tensile property of the high-strength material of the braided fabric is tested, so that the tested material and the clamp are free from skidding during the test process.
Description
technical field [0001] The invention relates to a fixture, in particular to a fixture for testing the tensile properties of light and thin materials. Background technique [0002] At present, carbon fiber woven composite materials are more and more widely used in the aerospace field. Many scientific research units and scholars are also exploring the application of carbon fiber composite materials in the automotive field, which involves testing the mechanical properties of carbon fiber woven composite materials. Known fixtures mainly include fixtures for measuring tensile test performance and compression test performance of metal materials and non-metal materials, while standard samples of metal materials are thicker, easy to clamp, and not easy to slip. There is no jig for testing the tensile properties of high-strength, thin-gauge braided materials. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provi...
