Abstract

A fiber composite material imitating the structure and function of coelacanth scales. The fiber composite material adopts a double-helix arrangement structure imitating coelacanth scales, and is formed by alternately laying up at least two groups of helical fiber resin layer structures; each group In the spiral fiber resin layer structure, the fiber resin layer takes the center line perpendicular to the center of the fiber resin layer as the axis, and rotates the same rotation angle from top to bottom to be arranged periodically; the fiber resin in each group of spiral fiber resin layer structure The layers are stacked alternately in sequence. The fiber composite material of the present invention imitates the double-helix fiber arrangement structure of the coelacanth scale, and obtains a fiber layer structure with stronger toughness than the traditional fiber composite material, which can well resist the shear force suffered by the fiber composite material and strengthen the structural toughness .

Description

technical field [0001] The invention belongs to the composite material technology in the field of new materials, and in particular relates to a fiber composite material imitating the structure and function of coelacanth scales. Background technique [0002] With the rapid development of aerospace and automotive technology, the requirements for lightweight, high-strength and tough materials are getting higher and higher. Among them, fiber composite materials have the characteristics of light weight and good mechanical properties, and are more and more widely used in various modern engineering technology fields. Due to the simple layout structure of traditional fiber composite materials, compared with metal materials, it is difficult to find an effective way to improve the interlayer toughness, and its strength is poor. Vehicles with higher speeds such as automobiles and airplanes often require higher toughness. Therefore, how to reduce the weight of fiber composite material...
