Problems solved by technology

[0004] In the existing technology, even though the natural coaxial spiral structure materials provide new ideas for the design of new materials, they are limited by design methods and manufacturing processes, resulting in a long-term development of material structure innovation and manufacturing technology oriented to the synergistic optimization of compressive and bending properties. In the exploratory stage, practical engineering applications cannot be carried out

Abstract

The invention relates to the technical field of additive manufacturing, in particular to a 3D printing system of a coaxial spiral structure reinforced composite material and a machining method. The 3Dprinting system of the coaxial spiral structure reinforced composite material and the machining method aim at solving the problems of compression resistance stability and bending resistance of an engineering supporting part, specifically, the system part comprises a three-dimensional forming manufacturing module, a computer control module and a controllable air pressure output system, wherein thethree-dimensional forming manufacturing module is used for outputting a matrix material and a cross-linking material according to two different preset rotation directions, so that the matrix materialand the cross-linking material construct a first printing body and a second printing body which are coaxial and are integrally formed; and the method comprises the following steps of material preparation, configuration of the matrix material and the cross-linking material in a programming material feeding module, coaxial spiral structure additive manufacturing and post-processing. Coaxial spiralarrangement of reinforcing phase discontinuous fibers in a composite material can be achieved, the compression resistance and the bending resistance of a reinforcing material are further reinforced ina coordinated mode, and the application range of engineering application is widened.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a 3D printing system and a processing method of a coaxial spiral structure reinforced composite material. Background technique [0002] Under the current trend, the key requirements for supporting structures in the field of infrastructure facilities such as wind power generation systems and building unit systems include: First, the key parts of the system components need to be resistant to compression in terms of structure and material selection and stability; second, system components need to have anti-bending characteristics within a predetermined range; and the existing support structures are often difficult to effectively meet the above requirements, which can be summarized as: unable to effectively cope with complex load environments. [0003] In contrast, in nature, biological materials and tissue structures effectively solve this contradictory problem, and c...
