Description

Technical Field

[0001] The invention relates to the technical field of composite material performance detection, in particular to a flexible detection device for fiber bulletproof composite materials. Background Art

[0002] Fiber composites are a type of composite material composed of fiber-reinforced materials and matrix materials. They are formed by the interaction between fibers and matrices, and combine the advantages of both materials in structure and performance. Fiber composites are widely used in various fields, such as aerospace, automobiles, construction, ships, etc. Strength testing can ensure the safety and reliability of these materials and prevent accidents caused by material failure. Through strength testing, researchers and designers can understand the mechanical properties of materials, thereby optimizing the structure and design of products and improving product performance and durability. During the production process, strength testing can help manufacturers ensure that the quality and performance of materials meet specified requirements, reduce waste and improve production efficiency.

[0003] According to a fiber composite material strength testing device proposed in Chinese patent CN117491170B, the fiber composite material can be clamped and fixed by the design of a fixed clamping device, ensuring that it will not move or slide during the stamping process, so as to facilitate the punch to perform a stamping test on the fiber composite material, while preventing the possibility of deformation of the fiber composite material after being stamped by the punch.

[0004] During use, the fiber bulletproof composite material flexibility detection device in the prior art first fixes the fiber bulletproof composite material and punches the fiber bulletproof composite material through a punch, thereby realizing flexibility detection of the fiber bulletproof composite material. Then, since the fiber bulletproof composite material is relatively soft in texture, the fiber bulletproof composite material is easily loosened during the stamping flexibility detection process, and the operator is required to manually straighten the fiber bulletproof composite material to perform flexibility detection. The process is cumbersome and complicated, and there is a certain risk factor. For this reason, we propose a fiber bulletproof composite material flexibility detection device.
