Aluminum honeycomb composite board is a new type of marine interior material that has been successfully developed by China and developed entirely by domestically produced green materials. It has obtained national patent certificate after the introduction of foreign advanced technology.
The aluminum honeycomb sandwich composite panel is composed of: fire panel + aluminum panel + aluminum honeycomb + aluminum panel + fire panel. The aluminum panel contains 98% aluminum, 1% magnesium, and is doped with a small amount of iron and silicon. After H19 ultra-cold hardening, the yield strength is 175 MPa, which conforms to American Standard QQ-A-250/26 and British Standard BS 1470. Its 3003 aluminum honeycomb core material is available in a variety of sizes to achieve the lowest stiffness and maximum strength of the sandwich structure. Its main structure aluminum panel and aluminum honeycomb core material and fireproof panel are bonded by Macrolast UK 8103 adhesive, which ensures the structural integrity and performance of the composite board. Macrolast UK 8103 is a solvent-free two-component. A polyurethane binder of a catalyst which forms a hard elastic substance by chemical reaction of a hydroxy compound and an isocyanate, has no change in volume before and after curing, and has good adhesion to the surface of the aluminum metal. During the bonding construction of the composite panel, a certain pressure is applied to the contact surface, thereby ensuring good contact between the glue and the two layers. After complete curing, the peel strength reaches 30-40 N/era and the shear strength reaches 7.5 MPa (based on German DIN 53282 standard). The aluminum honeycomb sandwich composite board has many advantages such as fireproof, soundproof, heat insulation, light weight, high strength, easy shape, and strong weather resistance. The product has been widely used in the train and shipbuilding industries, especially for modern high speed. Wall separation and decorative materials for trains, speed yachts and luxury passenger ships. The use of this material can reduce the self-weight of the train and the hull, greatly improve the navigation speed and load capacity of the vehicle, and save energy and reduce pollution.
In summary, the aluminum honeycomb sandwich composite panel structure is used as the inner partition wall of the compartment instead of the aluminum panel structure to separate the bulkhead, which not only ensures the strength and rigidity requirements, but also satisfies the requirements of sound insulation and heat insulation, and can reduce the structural weight. This is especially important for ships that demand both the fast performance of the ship and the comfort performance of the ship. Moreover, this honeycomb structure has been widely used as a separation material for foreign boat decoration in large quantities, and is a mature product. In this case, it is reasonable to use the aluminum honeycomb sandwich composite panel structure instead of the aluminum panel structure as the inner wall partition of the ship cabin. As long as the shipyard adopts reasonable and effective sealing measures and reasonable boundary fixed node type during the construction process, the aluminum honeycomb sandwich composite structure is feasible, reliable and practical. The selection of such a plate does not increase the cost, the construction is convenient, the process is practical, and the performance is guaranteed.
