Beschreibung
Zusammenfassung:	A metal sheet (Al alloy A6061) with a thickness of 0.2 to 1.0 mm with one component epoxy adhesive painted on a surface thereof having been subjected to chemical treatment is joined by adhesion with a plate material of CFRP prepared by laminating CFRP prepregs having carbon fiber aligned in uni-direction or having crossing carbon fiber. A metal plate (a high strength Al alloy material) is joined by adhesion with the metal sheet to be an integrated object via a layer of cured adhesive of epoxy resin adhesive having a thickness after adhesion of 0.3 mm or more. The integrated object can endure large change of temperature because of deformation of the layer of cured adhesive. A basic technique is provided such that a structure of CFRP joined by adhesion with a high strength metal material that can endure a severe several thousand cycle thermal shock test is prepared, enabling an aircraft, an automobile and a moving-type robot to be of a lighter weight.
