Embodiment Construction

[0036] In order to clearly and completely describe the technical solution of the present invention and its specific working process, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] The inner epidermis of scorpion claws is mainly composed of multiple helical structures1 nested by twisting and tilting, such as figure 1 shown. The helical structures are separated by layers of collagen fibrils when aligned in three dimensions. There are randomly distributed pores 3 longitudinally in the epidermis of the scorpion claw, such as image 3 As shown, the pore fibers in the scorpion pincers are hollow structures, which can be used as transmission pipes, such as transporting the required minerals, etc. At the same time, they also have mechanical properties and can improve the in-plane stiffness.

[0038] Such as Figure 4-9 As shown, the arrangement of the fiber layers of a bionic fiber-reinforced c...

Abstract

The invention discloses a fiber reinforced composite material simulating a scorpion chela structure and function. According to the composite material, a plurality of spiral structures are mutually nested to form a three-dimensional integral array structure, and the three-dimensional integral array structure is separated by a transition layer in the longitudinal direction; each spiral structure is formed by laying fiber layers, and each fiber layer is composed of a plurality of fibers which are arranged in a one-way mode; the fiber layers are spirally arranged around a torsion shaft which is perpendicular to fiber laminates and is arranged at the corners of the laminates, and meanwhile, the spiral structures are obliquely arranged around an inclined shaft which is perpendicular to the torsion shaft and is arranged in the planes of the fiber layers; and randomly distributed pore channels exist in the spiral structure. The structure of the scorpion chela is simulated, so that the impact resistance and the flexibility in the thickness direction of the structure are ensured, and meanwhile, the bending and shearing resistance of the fiber composite material is effectively improved through nesting of the spiral structure and the duct tubule structure.

Description

technical field [0001] The invention relates to the technical field of composite materials in the field of new materials, in particular to a fiber-reinforced composite material imitating the structure and function of scorpion pincers. Background technique [0002] In order to achieve the purpose of energy saving and emission reduction, lightweight has become a hot spot and problem in the transportation manufacturing industry. Most of the plates used in the aerospace and automotive fields are alloy materials. Due to the large molecular weight of metals, it is difficult to achieve light weight, and the composite material reinforced by fibers can not only meet the requirements of mechanical properties of the plate, but also achieve the purpose of light weight. [0003] Through the evolution process, natural organisms form a special structure—helical layered structure to resist natural enemies and capture prey. With the help of biomimicry, this structure is applied in the impa...
