LIGHT METAL/CFRP STRUCTURAL MEMBER

摘要

A structural member comprising a CFRP material deposited on the surface of a light metal material through an adhesive layer having a thickness of at least 10 mu m and not greater than 500 mu m, wherein the volume intrinsic resistance of the adhesive layer between the metal material and the CFRP material is at least 1 x 10<13> OMEGA .cm and the bonding strength at room temperature is at least 15 MPa. This member can reduce the weight of a conventional light metal/CFRP structural material, improve its electrolytic corrosion resistance, and remarkably improve strength and impact energy absorption performance. Therefore, this structural member can be applied to the fields that have not been applicable and can be mass-produced. Improvements in the reduction of weight, durability and reliability greatly contribute to environmental protection.
