Major engineering fields such as aerospace have put forward urgent demand for the lightweight and multifunctionalization of the structure. The core structure has multi -functional design advantages such as lightweight high -strength and heat insulation suction. Mechanics and multi -functional advantages have shown broad application prospects in modern high -end defense and industrial high -end equipment. In recent years, in response to different material systems and geometric topology, scholars at home and abroad have developed a variety of composite composite clamping core structure preparation processes and conducted in -depth research on their mechanical properties. application. The rigid panel of the core structure is far from the neutral axis under the support of the light core layer, which makes the inertia of the structure of the structure greatly improved and the mechanical performance is improved. However, how to ensure the reliable connection between the panel and the core layer to give full play to the advantages of the overall performance of the core structure is the focus of the academic and industrial circles for a long time.
Compared with thermosettic composite materials, the surface of thermoplastic resin can be lower, and the adhesive connection is limited to the intensity of the heating plastic composite clip core structure surface -core interface. Thanks to the characteristics of heating and cooling and cooling solids, the thermoplastic composite clip core structure can be connected by a melting connection.
