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

Abstract

The invention discloses a production method and production equipment for a thermoplastic composite core material. The production method comprises the following steps: compound molding geometrical sheets or flat sheets with structural layers and functional layers in a mold and continuously outputting the geometrical sheets or the flat sheets along the output direction of an assembly line; and cutting and processing the flat sheets or geometrical sheets into a plurality of core material unit sheets which are successively arranged along the output direction of the assembly line and stretch alongthe output direction of the wide side in a stripe-type direction, and stacking and splicing the core material unit sheets to a unit splicing body. The production equipment comprises a thermal compoundextruding mold, plastic material surface processing equipment, a cutting assembly, a guiding and positioning assembly, a rubber gun and the like. The invention provides the production method and theproduction equipment for the thermoplastic composite core material. The thermoplastic composite core material of a double-layered structure with high structural strength and functional diversity can be continuously produced with a low cost.

Description

technical field [0001] The invention relates to the technical field of material forming, in particular to a production method and production equipment of a 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 thermoplastic materials. ...
