Function regulation and control structure production method based on continuous fiber composite material 3D printing

Abstract

The invention relates to a function regulation and control structure production method based on continuous fiber composite material 3D printing, computer aided design software is used, according to the profile characteristic of a function regulation and control structure material product, a product three-dimensional model is established, then a corresponding performance analysis is carried out on the product by the computer aided design software, the function regulation and control design is carried out on the key characteristic areas, a fiber track curve is drafted, then the fiber track is subjected to algorithm optimization, the technical means during 3D printing is considered, the fiber track is adjusted to obtain the final fiber track curve, according to the track curve, a 3D printing path instruction file of the product is generated, and the instruction file is introduced into a continuous fiber reinforced composite material 3D printer, and the preparation of the function regulation and control structural material is completed. The method can realize dynamic control of fiber path and content in the composite material, and designability manufacture of the function regulation and control materials such as a variable stiffness fiber composite material, a thermal-conduction controllable material and a electromagnetic controllable material can be completed.
