Abstract

The invention relates to a fiber composite material imitating the structure and function of scales of coelacanth. According to the fiber composite material, a double-spiral arrangement structure imitating the scales of coelacanth is adopted and is formed by sequentially and alternately laying at least two groups of spiral fiber resin layer structures; in each group of spiral fiber resin layer structure, the fiber resin layers are periodically laid and arranged by sequentially rotating the same rotation angle from top to bottom by taking a center line vertical to the centers of the fiber resin layers as an axis; and the fiber resin layers in each group of spiral fiber resin layer structures are sequentially and alternately laid and stacked. The fiber composite material has the double-spiral fiber arrangement structure imitating the scales of coelacanth, so the fiber layer structures with higher toughness compared with a traditional fiber composite material are obtained, shearing force borne by the fiber composite material can be well resisted, and structural toughness is enhanced.

Description

Technical field[0001]The present invention belongs to composite materials in the field of new materials, and specifically, the present invention relates to a fiber composite material for imitation cavity ratclasia flakes.Background technique[0002]With the rapid development of automobile technology, the rapid development of automotive technology is getting higher and higher. Among them, the fiber composites have the characteristics of light quality and good mechanical properties, and the applications in modern various engineering technology are increasingly widely used. Since the contained structure of the conventional fiber composites is more single, the interlayer toughness is difficult to find an effective method compared to the metal material, and the intensity is poor. Transit vehicles with high speeds of automobiles, often require high toughness. Therefore, how to make the fiber composites achieve light quantification under the premise of toughness, it is the primary issue faci...
