If adhesively-bonded joints take the place of them, further weight-savings could be achieved. In particular, the adhesive bonding is essential to the metal-CFRP joints because they cannot assemble by integral moulding. However, the adhesive bonding currently takes a high cost in order to meet certification requirements and that is a disadvantageous point compared with the mechanical-fastening. One of approaches to reduce the cost of the adhesive bonding is an introduction of new surface-treating technologies. In this study, various surface treatments on titanium alloys or CFRP including latest technologies were picked up, and then wettability and surface geometry for each treatment were inspected, after that strength of adhesively-bonded single-lapped joints were measured. As for titanium alloys, the results showed that two surface treatments, Itro treatment and Laseridge, brought out acceptable strength. The strengths of those joints exceeded the level of conventional implemented surface treatment or the level of cohesive failure in adhesives which was estimated from finite element analysis. The high strength of Itro treatment may be caused by some kind of mechanism except for secondary bonding or mechanical interlocking (e.g. primary bonding) as a result of inspection of wettability and surface geometry. The other treatment, Laseridge, generated deep grooves on the surfaces whose depth was over 100μm. The deep grooves may cause mechanical interlocking as a mechanism of adhesive bonding. These treatments would attain cost reduction and quality stabilization of adhesive bonding because the procedures are quite simple compared with the traditional way. In other words, they are practical treatment of promise. As for the strength of adhesively-bonded CFRP joints, sandpaper abrasion showed the highest strength and atmospheric plasma treatment was second. However, a process of the atmospheric plasma treatment is more simple than the sandpaper abrasion, therefore it has a potentiality as the next-generation technology.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
