Abstract

The invention discloses a preparation method of a wood-based sound insulating and electromagnetic shielding cross double-X lattice sandwich structure, which relates to the field of building materials.The structure is mainly composed of upper and lower coatings, upper and lower veneers, upper and lower fiber reinforced resin layers, upper and lower panels, a core layer and a filling material. Thelattice columns of the core layer are cross-distributed to constitute the basic elements of the cross double-X lattice sandwich structure, and the basic elements are distributed in the core layer according to a reasonable arrangement mode. The structure preparation method designed by the invention is reasonable, and the materials are green and environment-friendly. The panels have high stiffness.The core material is lighter and can increase the ability of the structure to withstand transverse shearing. The filling material and the surface layer have sound insulating and electromagnetic shielding functions, and structure and function integration is realized. The application of the preparation method in the field of wood structure buildings widens the utilization scope of wood resources andhas great significance to the effective utilization of wood resources.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a method for preparing a wood-based sound insulation and electromagnetic shielding cross double X-shaped lattice sandwich structure. Background technique [0002] The composite lattice sandwich structure has the characteristics of low density, high specific rigidity, high specific strength and good designability. The lattice sandwich structure made of metal or carbon fiber reinforced materials has been widely used in high-speed traffic engineering and aerospace engineering . However, the research of lattice sandwich structure with wood or wood composite material as the main body is rare, and its application as a wood engineering material in wood structure construction is worth exploring. [0003] The traditional lattice structure design scheme usually separates the mechanical performance requirements of the structure from the functional requirements. That is, some materials are used t...
