A joined body includes: a first compact that includes a fiber-reinforced resin and a fiber exposure portion where a fiber of the fiber-reinforced resin is exposed, the fiber exposure portion being formed on at least a part of a surface of the first compact; a second compact that is joined to the first compact at the fiber exposure portion of the first compact; and a joint portion that is interposed between the fiber exposure portion of the first compact and the second compact.

A novel device and method enabling insert staking of brass inserts into plastic.

The aerospace component joints comprise a first component member comprising a first bonding face, a second component member comprising a second bonding face, one or more bond-enhancing features, and an adhesive layer forming a bond between the first and second bonding faces. The one or more bond-enhancing features comprises a plurality of reinforcing protrusions integral with the first component member, projecting from the first bonding face through the adhesive layer, and into the component member and/or one or more adhesive-receiving recesses defined in the first or second bonding faces and filled by the adhesive layer. The methods of preparing a component member for an aerospace component joint comprise integrating one or more bond-enhancing features into the component member. The methods of forming the aerospace component joint comprise positioning and adhesive-bonding the first bonding face to the second bonding face, and integrating the bond-enhancing feature(s) into the aerospace component joint.

A process, apparatus and a catheter and a flexi needle for medical applications formed by the process of selecting a tubular flexible member and a metal/ceramic cap member to be securely joined to the tubular member, placing the cap member in engaging relation with a holding member of a material joining device, securing the tubular member on a positioning member of the material joining device, positioning a distal end of the tubular member in engaging relation with an end of the cap member positioned in the holding member, and rotating the holding member and maintaining the tubular member in frictionally engaging relation with the cap member to melt or soften a predetermined portion of the distal end of the tubular member engaged with the cap member to integrally join a predetermined portion of the distal end of the tubular member within the cap member forming a joined composite member.
