Aluminum plastic composite plate having honeycomb structure

Abstract

The invention discloses an aluminum plastic composite plate having a honeycomb structure. The aluminum plastic composite plate which is formed by a core (1) and aluminum panels (2) clamping two sides of the core (1) is characterized in that the core (1) adopts a single-layer honeycomb structure and is composed of a one-piece honeycomb frame (3) and fixing cylinders (4); orthohexagonal honeycomb holes are uniformly distributed on the honeycomb frame (3) in an equal interval arrangement manner; the fixing cylinders (4) are embedded into all the honeycomb holes; thick plastic walls (5) are formed on the honeycomb frame (3); and the fixing cylinders (4) and the aluminum panels (2) form one body through compounding with the thick walls (5). The self core performances of the aluminum plastic composite plate having the structure are improved, the combination structure of the core and aluminum panels of the aluminum plastic composite plate having the structure is improved, and the comprehensive performances of the aluminum plastic composite plate having the structure are better than that of present aluminum honeycomb plates.

[0004] Aluminum honeycomb panel is a kind of sandwich structure plate. Thin aluminum plate is bonded to relatively thick lightweight aluminum honeycomb core material to form a hard and light plate composite material with light weight, high strength, especially high rigidity. Features, as early as the 1950s, aluminum honeycomb panels have been used in aviation and aerospace fields. With the advancement of technology and mature technology, their application range has become more and more extensive. The strip-shaped aluminum material is formed by bonding or welding, and there are inevitably connection defects in the process of bonding or welding. The combination of the honeycomb core and the panel of the existing aluminum honeycomb panel is a linear combination, which not only requires more processing of the honeycomb core High, and the strength of the plate is restricted, in view of these deficiencies, a honeycomb plate is disclosed in the Chinese patent document CN101054005B, which is composed of a honeycomb core and panels sandwiched on both sides of the honeycomb core, and its feature is: the honeycomb core is a whole piece of foil A series of concave-convex staggered support bodies are processed on it. The support body is composed of vertical ribs and horizontal platforms to form an integral concave-convex structure. The vertical ribs form a closed-loop structure. The vertical ribs of adjacent support bodies are shared. , the honeycomb panel with this structure not only improves the strength and stiffness of the honeycomb core itself, but also changes the connection between the honeycomb core and the panel from the linear combination of the T-shaped structure to a planar combination, which strengthens the connection between the honeycomb core and the panel. Bonding strength, but this kind of honeycomb panel is not only difficult to realize the core panel structure, but also loses some properties of the honeycomb panel, such as sound insulation and heat insulation and structural rigidity. On the other hand, aluminum-plastic panels are a new type of material. The internal stress structure has good sheet properties, among which the high-performance bonding material polymer film is the key to the forming of aluminum-plastic panels
