Title:
HONEYCOMB CORE SANDWICH COMPOSITE PANEL AND MANUFACTURING METHOD THEREFOR, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/128407
Kind Code:
A1
Abstract:
The present invention provides a honeycomb core sandwich composite panel, comprising a honeycomb core material formed by a plurality of units arranged in rows; the units are hexagonal cylinders formed around by side walls, the side walls each comprise a support layer and an adhesion layer, and upper and lower surfaces of the honeycomb core material are respectively provided with panels, the panels each comprise a main body layer and an interface layer, the interface layers being layers respectively connected to the upper and the lower surfaces of the honeycomb core material, the main body layers being provided on the interface layers, the main body layers being made of a continuous fiber-reinforced thermoplastic material, and the interface layers being made of the continuous fiber-reinforced thermoplastic material or a thermoplastic resin film. The manufacturing method of the present invention is simple, better mechanical properties can be obtained by using fewer materials, and production costs are reduced. The honeycomb core sandwich composite panel manufactured by means of a thermal composite process has excellent mechanical properties, effectively improving the compressive strength and bending strength, and further improving the stability of the production process.
