Honeycomb core material, manufacturing method of honeycomb core material, composite honeycomb structure and manufacturing method of composite honeycomb structure

Abstract

The invention discloses a honeycomb core material, a manufacturing method of the honeycomb core material, a composite honeycomb structure and a manufacturing method of the composite honeycomb structure. The honeycomb core material comprises a honeycomb plate and a plurality of foaming layers, the honeycomb plate comprises a plurality of honeycomb holes, the honeycomb holes straightly penetrate through two opposite surfaces of the honeycomb plate, the foaming layers are respectively filled in the honeycomb holes, the foaming layers are tightly connected with the wall surfaces of the honeycomb holes and are formed by pouring a hard foaming agent; and according to the composite honeycomb structure, the honeycomb core material serves as a core layer, and a first adhesive layer, a fiber material layer, a second adhesive layer and a surface layer are sequentially stacked on the two opposite faces, provided with honeycomb holes, of the honeycomb core material. The honeycomb core material and the composite honeycomb structure are utilized, and the advantages of light weight, high strength, fire prevention, heat insulation, good sound insulation and the like can be achieved at the same time.

Description

technical field [0001] The present invention relates to a composite structure, in particular to a honeycomb core material, a manufacturing method of the honeycomb core material, a composite honeycomb structure, a composite Manufacturing method of honeycomb structure. Background technique [0002] By the way, wood, metal and other decoration materials are indispensable and important materials in all fields. In addition to being used as partition materials for buildings such as homes and offices, they are also widely used in automobiles, high-speed trains, aircrafts, ships, etc. among the means of transport. With the development of modern industry and technology, more and more structures are focusing on lightweight in order to meet the needs of consumers or achieve better performance. Therefore, in addition to wood and metal, there are many more decoration materials. The choice of lightweight materials, such as honeycomb panels made of metal. [0003] Although honeycomb pan...

Problems solved by technology

[0003] Although honeycomb panels are used in buildings, vehicles and other objects, they can simultaneously have the functions of light weight, high Z-axis strength and fire resistance, but the structural strength of the X-axis and Y-axis directions of the honeycomb panel is lower than that of the Z-axis direction. Much weaker; moreover, honeycomb panels have good sound and heat transfer effects, so if honeycomb panels are used in partition walls that require sound insulation and heat insulation, it is a disadvantage
