Technical Field

[0001] The utility model relates to the technical field of tensile performance of bio-based materials, in particular to a tensile performance testing structure based on bio-based materials. Background Art

[0002] In recent years, with the advancement of materials science, tensile performance testing technology has also been continuously developing. Tensile performance is an important indicator to measure the strength and toughness of materials under stress. Traditional testing methods include using universal testing machines to measure the deformation and fracture characteristics of materials under tensile force. Combined with high-resolution image analysis, sensor technology and computer simulation, more accurate performance data can be obtained. Tensile performance testing based on bio-based materials is not only of great significance in the field of scientific research, but also plays a role in practical applications. For example, in industries such as construction, automobiles, and aerospace, the performance data of these materials can guide design and optimization to better meet engineering requirements.

[0003] At present, most of the tensile performance testing structures of bio-based materials on the market often cause the bio-based materials to fall off during the tensile performance test due to loose clamping or incomplete fixation of the bio-based materials during the test, resulting in inaccurate experimental data of the tensile performance test.
