Abstract

According to the laminated composite material of the engineering plastic and the porous metal plate. The bottom layer and the top layer are the engineering plastic or the engineering plastic containing a reinforcing phase, at least one layer of metal pore plate is arranged between the bottom layer and the top layer, and when the number of the metal pore plates between the bottom layer and the top layer is at least two, an engineering plastic layer or an engineering plastic layer containing a reinforcing phase is arranged between the metal pore plates, the engineering plastic layer or the engineering plastic layer containing the reinforcing phase and the metal pore plates are hardened into a whole, and the engineering plastic layer or the engineering plastic layer containing the reinforcing phase penetrates through pore channels of the metal pore plates to form a network interpenetrating structure. The preparation method of the laminated composite material comprises the following steps of paving the engineering plastic powder or the engineering plastic powder containing the reinforcing phase in a mold, heating and melting the engineering plastic powder or the engineering plastic powder containing the reinforcing phase, putting the metal pore plate, and preserving heat and pressure after the metal pore plate and the engineering plastic powder or the engineering plastic powder containing the reinforcing phase are completely put in the mold, and then taking out the mold filled with the hot-pressing product, and naturally cooling to room temperature to obtain the laminated composite material.

Description

technical field [0001] The invention belongs to the technical field of fiber-metal hybrid laminates, and relates to a laminated composite material of engineering plastics and porous metal plates and a preparation method thereof. Background technique [0002] Fiber-metal hybrid laminates (engineering plastic metal hybrid laminates) are composite laminates formed by alternating layers of metal sheets and fiber-reinforced resin prepregs or engineering plastics and then heat-pressed and solidified, thus combining metal materials and fiber composite materials or The advantages of engineering plastics are higher specific strength, specific stiffness and excellent high temperature resistance, and have broad application prospects in the fields of aviation and biomaterials. However, due to the multi-interface layers of such materials, especially the poor bonding reliability of the metal / resin interface, the main problem is interface failure (interface delamination), resulting in redu...
