Abstract

The invention discloses an integral forming process of a foamed aluminum and fiber reinforced resin-based composite sandwich panel, which comprises the following steps: step 100, carrying out chemical coating treatment on the surface of a foamed aluminum plate to obtain a primarily treated foamed aluminum plate; 200, performing pore filling treatment on the surface of the foamed aluminum plate subjected to primary treatment by using a dielectric material to obtain a foamed aluminum plate subjected to secondary treatment; 300, laying two fiber-reinforced resin-based composite boards symmetrically on the two sides of a mold, and placing the foamed aluminum board subjected to secondary treatment between the two fiber-reinforced resin-based composite boards; and 400, heating the sandwich type pressing equipment to the preset temperature, and enabling a combined structure formed by the two fiber-reinforced resin-based composite boards and the foamed aluminum board subjected to secondary treatment to be pressed and formed under the preset pressure through the sandwich type pressing equipment. According to the invention, the coupling property between the foamed aluminum sandwich layer and the composite material laminated plate is improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an integral molding process of aluminum foam and fiber-reinforced resin-based composite sandwich panels. Background technique [0002] Foamed aluminum is made by adding additives to pure aluminum or aluminum alloy and undergoes a foaming process. It has the characteristics of metal and air bubbles at the same time. Surface coating, with excellent physical and chemical properties and recyclability. [0003] However, the existing aluminum foam has a single structure, so its mechanical properties and flame-retardant and heat-insulating properties are poor, and it is difficult to be used in occasions that require high mechanical properties and flame-retardant and heat-insulating properties. The current solution to these problems is to combine the mechanical properties of foamed aluminum and play a barrier role by using foamed aluminum as a sandwich material and connectin...
