<P>PROBLEM TO BE SOLVED: To provide the technique for rigidly adhering metal alloy to CFRP with an epoxy adhesive. <P>SOLUTION: Roughness of micron order is produced on the surface 31 of the metal alloy, a super-fine ruggedness is formed in a ruggedness of the roughness, the surface layer of the super-fine ruggedness is formed as a thin layer of metal oxide or metal-phosphorus oxide. On the surface of the surface layer, a first adhesive (one-component epoxy adhesive) which contains inorganic filler having a particle size center of 5-20 μm and super-fine inorganic filler having a particle size of 100 nm or less is applied, the metal alloy is enclosed in an air-tight container, decompression and compression are performed, thereafter, the adhesive is cured and, further, the layer of the cured adhesive is roughened. On the other hand, the CFRP 32 is cured and the surface of the CFRP is roughened. To both of the roughened metal alloy and the CFRP, a second adhesive (one-component or two-component epoxy adhesive) containing inorganic filler is applied, both members are enclosed in the air-tight container, decompression and compression are performed, thereafter, the both members are fixed, the second adhesive is cured and, thereby, the both are integrated. <P>COPYRIGHT: (C)2011,JPO&INPIT |
