Thermoplastic composite core material and equipment comprising same

Abstract

The invention discloses a thermoplastic composite core material and equipment comprising the same. The thermoplastic composite core material comprises a plurality of core material unit sheets extending in a first direction. The core material unit sheets are laminated and spliced in a second direction to form a unit spliced body; a plurality of shaft hole structures which are sequentially distributed in the first direction at least are formed in the unit spliced body; each core material unit sheet has a double-layered sheet structure and comprises a functional layer with compatibility and a structural layer for bearing load; each functional layer and the corresponding structural layer are in thermal composite connection; and at least part of the sheet surface of each core material unit sheet is provided with geometric bodies which are sequentially distributed in the length direction of the core material unit sheets and are non-closed so as to be spliced to form the corresponding shaft hole structure. By the thermoplastic composite core material disclosed by the invention, light weight and heavy load can be realized, furthermore, various different properties can be combined by combining the structural layers and the functional layers, and thus, the thermoplastic composite core material is suitable for various application fields.

Description

technical field [0001] The invention relates to the technical field of material forming, in particular to a thermoplastic composite core material and equipment comprising the thermoplastic composite core material. Background technique [0002] Honeycomb core panels not only have the advantages of low density and high strength, but also have many excellent properties such as shock absorption, sound insulation, and heat insulation, so they are widely used in ships, transportation, aerospace and other fields. Among them, thermoplastic honeycomb core materials have the advantages of extremely high specific strength, recyclable waste materials, and good thermoforming performance. Compared with traditional metal materials and non-renewable thermosetting materials, they are more competitive. [0003] Thermoplastic honeycomb core materials on the market are mainly produced by blow molding or blister technology, which is limited by processing pressure and plastic properties of thermo...

AI Technical Summary

Problems solved by technology

Existing honeycomb core materials usually create new functions by adding functional fillers dispersedly into the matrix material of the honeycomb wall, but the functional materials are limited by the proportion that can be added and the distribution characteristics of the dispersion. Functional effects are also greatly limited, resulting in bottlenecks in the diversification of functional requirements for existing thermoplastic core materials
