Embodiment Construction

[0036] The technical solutions of the present invention and their specific operations are described herein, which will be further described in detail below with reference to the accompanying drawings and examples.

[0037] The inner surface skin of the scorpion chelate is mainly nestled from a plurality of helical structures formed by twisting and inclined. figure 1 Indicated. The helical structure is arranged in a three-dimensional space, separated by the collagen fiber layer 2. In the laminated hole 3, such as image 3 As shown, the pore fibers in the scorpion zone are hollow structures, and can be used as a transmission conduit, such as minerals required for transmission, etc., and also have mechanical properties, which can improve the surface stiffness.

[0038] like Figure 4-9 As shown, the laying method of a bionic fiber reinforced composite fiber layer in the present invention is based on the sequence of collagen fibers in the scorpion chelate, and is nested by a plurality o...

Abstract

The invention discloses a fiber-reinforced composite material imitating the structure and function of scorpion pincers. A plurality of helical structures are nested to form a three-dimensional overall array structure, and are separated by transition layers in the longitudinal direction; each helical structure is arranged by fiber layers. The fiber layer is composed of a plurality of unidirectionally arranged fibers; the fiber layer is helically arranged around the torsion axis perpendicular to the fiber ply and at the corner of the ply, and at the same time, the helical structure is perpendicular to the torsion axis And the inclined axes in the plane of the fiber layer are arranged obliquely; there are randomly distributed pores in the helical structure. The invention bionics the structure of the scorpion pincers, while ensuring the impact resistance of the structure and the flexibility in the thickness direction, and effectively improves the bending and shearing resistance of the fiber composite material through the nesting of the helical structure and the small tube structure of the channel.

Description

Technical field [0001] The present invention relates to the technical field of composites in the field of new materials, and more particularly to a fiber reinforced composite material of imitation of slats and functions. Background technique [0002] In order to achieve the purpose of energy saving and emission reduction, it is lightweight into hotspots and problems in the current vehicle manufacturing industry. Most of the plates used in aerospace and automotive areas are alloyed materials. Due to the larger molecular weight, it is difficult to achieve a lightweight, while the fiber-enhanced composite can achieve both the mechanical properties of the sheets or lightweight. [0003] Through the evolutionary process, natural organisms form a special structure-spiral layered structure to resist the natural enemies and capture the prey. With bionics, this structure is applied to the anti - impact design of composite laminate such as aerospace, automobiles. The conventional helical s...
