Technical Field

[0001] The utility model belongs to the technical field of testing equipment and relates to a device for testing the performance of composite materials. Background Art

They can give full play to the advantages of various materials, overcome the defects of single materials, expand the application range of materials, and have the characteristics of light weight, high strength, easy processing and molding, excellent elasticity, chemical corrosion resistance and good weather resistance. Composite materials need to be tensile tested before use. Through tensile testing, important basic mechanical properties such as material elasticity, plasticity, strength and toughness can be determined. When conducting a tensile test, the composite material is usually stretched to both sides until it breaks, but existing testing equipment cannot stretch composite materials at different angles, which has certain limitations.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1 to Figure 2 As shown,

[0018] A device for testing the performance of composite materials, characterized in that it includes a test platform body 2, a rotating frame 3 is rotatably connected to one side of the test platform body, a first drive motor that drives the rotating frame 3 to rotate is provided on the test platform body, a second drive motor 4 is fixedly connected to the rotating frame 3, a turntable 5 is fixedly connected to the output shaft of the second drive motor 4, and a sliding frame 6 is slidably connected to the other side of the test platform body 2, a first push rod motor 7 that drives the sliding frame 6 to move is provided on the test platform body, a placing table 8 and a second push rod motor 9 are both provided on the turntable 5 and the sliding frame 6, and a pressure block 10 is fixedly connected to the push rod of the second push rod motor 9.

[0019] In this embodiment, the two ends of the composite material that needs to be tensile tested are placed on the placement table 8, and the second push rod motor 9 is started. The second push rod motor 9 drives the pressure block 10 to descend and press the two ends of the composite material. After pressing the composite material, the first push rod motor 7 drives the sliding frame 6 to retreat and perform a tensile test on the composite material. When the composite material is stretched at different angles, the first drive motor drives the rotating frame 3 to rotate, so that the composite material is bent up and down and stretched, and the second drive motor 4 drives the rotating turntable 5 to rotate, so that the composite material is rotated left and right for stretching. The testing equipment can realize the stretching of the composite material at different angles, so that the test results are more comprehensive.

[0020] In this embodiment, a V-shaped groove 11 is provided on the placing table 8 and the pressing block 10. The V-shaped groove 11 is provided so that the cylindrical composite material can be better clamped.

Through the slide groove 12 and the slider 13, the slide frame 6 is more stable during the tensile test.

[0022] In this embodiment, a support plate 14 is fixedly connected to the test platform body 2, and a support plate 16 is connected to the support plate 14 via a spring 15, and the sliding frame 6 can be supported on the support plate 16. After the composite material is stretched and broken, the sliding frame 6 retreats due to inertia, hits the support plate 16 for support, and the elastic force of the spring 15 is offset, thereby protecting the equipment.

[0023] In this embodiment, a collecting box 17 is provided at the lower end of the test platform body 2. The collecting box 17 is used to collect the broken composite material.
