Biomimetic composite material and preparation method thereof

Abstract

The invention discloses a biomimetic composite material and a preparation method thereof. The biomimetic composite material includes alternately arranged alternating sinusoidal fiber resin layers andspiral fiber resin layers. The sinusoidal fiber resin layers and spiral fiber resin layers are in a sinusoidal radius of curvature incremental transition connection. Each sinusoidal fiber resin layeris formed by laying multiple layers of fiber resin layers in a shape of a sinusoidal curve. Each spiral fiber resin layer is formed by cyclic laying of fiber resin layers for several cycles accordingto a cycle of rotating the same angle as the upper layer during each laying and finally rotating 180 degrees. The fiber resin layers are formed by infiltrating fibers with resin. The biomimetic composite material learns from the structure and function enlightenment of anti-impact fiber of sticks of Mantis shrimps, realizes the mutual coupling and synergistic effect of different fiber structures, improves the performance of the layered composite material, and solves the shortcomings of single layered structure, difficult improvement of impact resistance and the like of a commonly used layered fiber composite material.

Description

technical field [0001] The invention relates to the technical field of preparation of functional composite materials, in particular to a bionic composite material and a preparation method thereof. Background technique [0002] With the continuous development of modern engineering technology, the requirements for engineering materials in aviation, aerospace, automobile, rail transit and other fields are constantly increasing. In the field of modern engineering technology, materials are often required to have relatively light weight under the premise of good mechanical properties, so as to reduce the corresponding energy consumption. While meeting the requirements of lightweight, it is often necessary to ensure the reliability of engineering components. As a common material damage method in the engineering field, impact damage often leads to material failure and seriously affects the mechanical parts and related instruments. Stable operation and normal work. Therefore, how t...
