Abstract

The invention is suitable for the technical field of sandwich-structure composite materials and discloses a forming method of a fiber-reinforced sandwich-structure composite material. A sandwich structure is prepared by using a 3D (three-Dimensional) printing technology; the sandwich shape can be freely designed without chemical bonding and compression molding forming; a designed mold is relatively high in precision; on one hand, the material formed by the 3D printing technology is relatively high in precision; the sandwich-structure material prepared by the method is relatively high in precision, and meets the requirements of industrial production; on the other hand, by adding the high-performance fiber-reinforced material, the bending resistance and impact resistance of the sandwich structure can be further improved so that the performances thereof can approach or even reach the performance of a solid to implement the lightweight and high-performance effect; and the forming method ofthe fiber-reinforced sandwich-structure composite material has huge market economic values and wide application prospects.

Description

【Technical field】 [0001] The invention relates to the technical field of sandwich structure composite materials, in particular to composite materials combined with fibers and polylactic acid, and a rapid prototyping method for sandwich structure composite materials. 【Background technique】 [0002] The preparation of sandwich structure composite materials usually adopts the method of segmented manufacturing and chemical agent bonding. The traditional molding method has the disadvantages of complicated process, special mold and poor combination at the junction of the interlayer and the panel, which cannot meet the requirements of modern industrial development. [0003] In order to improve the above shortcomings, it is necessary to propose a molding method for fiber-reinforced sandwich structure composite materials. The use of 3D printing rapid prototyping method can effectively solve the above problems, improve the molding efficiency and molding accuracy of the material, and a...
