Abstract

The invention relates to a light-weight and high-strength thermoplastic composite material sandwich board and a production method thereof. The light-weight and high-strength thermoplastic composite material sandwich board comprises two panels and a sandwich layer, wherein the sandwich layer is fixedly arranged between the two panels. The preparation method comprises the following steps: putting the sandwich layer between the two panels; and sticking the two panels on the front and rear faces of the sandwich layer by a thermoplastic glue film through a hot pressing process and a cold pressing process to produce the thermoplastic composite material sandwich board. The panels are continuous fiber enhanced thermoplastic composite material boards and the sandwich layer is made of a honeycomb aluminum material. Compared with the prior art, the thermoplastic composite material sandwich board has the advantages of light weight, high strength, heat preservation, fireproof prevention, moisture prevention, corrosion prevention and the like.

Description

technical field [0001] The invention belongs to the technical fields of architectural decoration and transportation, and in particular relates to a lightweight and high-strength thermoplastic composite sandwich panel and a manufacturing method thereof. Background technique [0002] With the rapid development of science and technology, there are endless types of sandwich panels used in the fields of building decoration and transportation. Not only is the structure and panel style ingenious, but also the function has undergone earth-shaking changes. People require not only beautiful appearance and reliable quality, but also light weight, high strength, flame retardant, heat preservation, heat insulation, anti-corrosion and other functions. Sandwich panels currently on the market include metal panels and other types of non-metallic panels, such as wood panels, gypsum panels, and glass steel panels. [0003] Commonly used metal sandwich panels are composed of color steel plate...
