Microstructural bionic composite board based on China hemp fiber composite

Abstract

The invention discloses a microstructural bionic composite board based on a China hemp fiber composite. The natural China hemp fiber composite is selected as face plate layers, thick cordage preimpregnated thermal plastic or thermal setting material and fine cordages are selected as framework materials in a reinforcing layer, the fine cordages are adopted as reinforcing ribs for fixing and supporting, and thus the hemp fiber bionic composite board with a specific microstructure is formed. Two or more face plate layers can be arranged as needed; the face plate layers are formed by combining a China hemp fiber composite plate with one or more of a carbon fiber composite plate, an aramid fiber composite plate or other plates, and thick cordages of the framework part are distributed in orthogonality or in parallel or by 45 degrees or by 60 degrees. The microstructural bionic composite board is good in environment-friendliness, light, high in rigidity and strength, good in energy absorption performance and capable of being widely applied to the fields such as automobiles, buildings, decoration and packages, has good application prospects and is environmentally friendly and novel.

Description

technical field [0001] The invention relates to the field of design and manufacture of automobile materials, in particular to a microstructure bionic composite board based on hemp fiber composite material. Background technique [0002] With the progress of society, people's demand for environmental protection, energy saving and material saving is constantly increasing, and the requirements for materials for automobiles and automobile interior parts are also getting higher and higher, and the market competition is fierce; lightweight is the trend of automobile development, so lightweight The application of materials in automobiles will also become more and more common; hemp fiber has the characteristics of anti-wrinkle, deodorization, sterilization, anti-ultraviolet radiation, odor absorption, moisture absorption and perspiration, etc. It is a new generation of natural fibers discovered by humans after cotton, wool and silk. fiber. Hemp fiber is known as the "King of Natural...

AI Technical Summary

Problems solved by technology

Hemp fiber is known as the "King of Natural Fibers". As an organic material, hemp fiber has good performance and is environmentally friendly. Now common hemp fiber composite panels are composed of direct filling materials between panels. The hemp fiber composite board of the present invention does not have sufficient rigidity and strength in terms of mechanical properties; Due to great limitations, it is necessary to improve the existing hemp fiber composite board to increase its stiffness and strength to meet the needs of use
