Abstract

The invention provides a lightweight composite lattice laminboard and a preparation method thereof. The lightweight composite lattice laminboard comprises a pyramid-type lattice core, an upper panel and a lower panel; the upper surface of the pyramid-type lattice core is fixedly connected with the upper panel through a blind rivet; the subface of the pyramid-type lattice is fixedly connected with the lower panel through a blind rivet; the preparation method comprise the following steps of 1, preparing a rhombic metallic net plate; 2, designing a bending mold; 3, preparing the pyramin-type lattice core; 4, drilling holes; 5, riveting. The lightweight composite lattice laminboard and the preparation method provided by the invention can solve the problems that since the metallic plate and core are connected by adopting a welding method, the cost is high, and since the composite plate and core are connected by adopting an adhesive, shear tensile bearing capacity is not enough, the connection strength is low, the connection quality is not easy to detect and a big plate is not easy to prepare in the prior art.

Description

technical field [0001] The invention relates to a sandwich panel and a preparation method thereof, in particular to a lightweight composite lattice sandwich panel and a preparation method thereof. Background technique [0002] The lightweight porous sandwich lattice structure is a new type of structure developed in the past ten years with the goals of weight reduction, energy saving, and purification. It has high specific stiffness, high specific strength, strong designability, and meets multi-functional requirements. The advantages. The lattice structure can not only effectively bear external loads, but also be easy to wire, implant micro-devices, fill functional materials, etc., so this type of structure is an ideal structural platform for ultra-light and multi-functional structures. It has wide application potential and application prospect in the fields of aerospace, automobile and ship, civil engineering, military security and so on. [0003] There are two main types ...
