Problems solved by technology
The former has a simple process, but the production is discontinuous, and the production efficiency is low and the cost is high
Although the latter has continuous process production, there is more material waste
It is especially important that the thermoplastic core materials produced by the two production methods can only have a single honeycomb structure, and cannot be filled with structural fillers or functional fillers, or after filling with fillers, it is easy to cause filler wall breakage in the subsequent process, which cannot Meet the diverse needs in practical applications

Abstract
The invention discloses a thermoplastic combination core material. The thermoplastic combination core material is a unit combination body which at least comprises a plurality of geometrical sheet units stretching along a first direction and laminated and spliced along a second direction. Non-closed geometrical shapes which are represented repeatedly along the first direction are formed on the surfaces of the sheets of the geometrical sheet units, and the geometrical shapes are used for splicing and forming a plurality of axle hole structures successively distributed along the first direction in the unit combination body. The unit combination body comprises a plurality of geometrical branch parts divided along the second direction, and any two adjacent geometrical unit branch parts have different geometrical shapes. The novel thermoplastic combination core material provided by the invention has relatively large wall thickness, can be filled with a material, is high in strength and rich in function, and the same core material has various different strength and performance, so that the thermoplastic combination core material is suitable for the field, in which the demand on the structural strength is severe and the demand on functionality is diverse. The thermoplastic combination core material can be continuously produced and processed on a large scale, so that the diverse demands in actual application are met.
Description
technical field [0001] The invention relates to the technical field of material molding, in particular to a thermoplastic combined core material. Background technique [0002] Thermoplastic honeycomb composite materials have been widely used in light-duty freight, cold chain logistics, building formwork and aviation logistics because of their superior light-weight and heavy-duty performance compared to traditional metal structural materials, but are limited by processing technology, processing efficiency and Processing costs, the existing types of thermoplastic sandwich composite materials formed by thermoplastic honeycomb core materials are limited, and the existing processing technology is difficult to produce thermoplastic core materials that can be filled with a large number of functional fillers and structural fillers, or the production efficiency is poor, and the processing cost is high. The quality is uncontrollable. With the increasingly urgent demand for thermoplas...
