A composite material forming device includes a pressurizing unit, heating unit, a movement mechanism, and a control unit. The device processes a composite material in which reinforced fibers have been impregnated with a thermosetting resin from a softened state or semi-cured state into a cured state while forming the composite material into a prescribed size and prescribed shape. The pressurizing unit applies pressure to a prescribed region of the composite material. The heating unit applies a magnetic field to the prescribed region of the composite material to which pressure has been applied by the pressurizing unit, thereby heating a prescribed region of the composite material. The movement mechanism causes the pressurization region and heating region to synchronously move by simultaneously changing the position of a first member relative to the composite material and the position of the heating unit relative to the composite material.

A composite structural component includes a longitudinally extending elongated tubular duct of a first material having a first coefficient of thermal expansion, and a plurality of longitudinally extending elongated reinforcing members of a second material.

Each of the plurality of reinforcing members is retained in a corresponding one of a plurality of longitudinally extending recesses formed in a peripheral wall of the tubular duct.

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.

A distal end portion on a side of an object to be joined of a resonator for joining is so configured that a plurality of protrusions each having an outer face not including an angular shape edge are stacked in two or more steps in a direction in which the resonator for joining and a reception jig for joining oppose to each other and that a shape of a protrusion on the side of the object to be joined is made smaller than a shape of a protrusion on a side of the resonator for joining. With this configuration, it is possible in the process of joining the object to be joined to first concentrate energy of acoustic vibration or ultrasonic vibration on a protrusion having a smaller shape serving as a first step protrusion to trigger to start displacement, then smoothly join, by a protrusion having a larger shape serving as a second step protrusion, a part of the object to be joined existing around the protrusion having the smaller shape, whereby metal foils can be joined without using a protection member for protection of the metal foils. A distal end portion having a plurality of protrusions stacked in two or more steps may be provided in the reception jig.

The present invention relates to alternative methods of joining a solid part (1) and a polymer (2). The methods comprise attaching a primer layer (4) with a predetermined surface chemistry, density and thickness covalently to at least a part of a surface (3) of the solid part (1). Some embodiments of the invention further comprise polymerizing second molecules onto the primer layer (4) so that the surface (3) is at least partly covered with surface immobilized polymer brushes (8). The surface (3) of the solid part (1) is brought into contact with the polymer (2) and a predetermined temperature profile is applied resulting in covalent bonds (6) being established between the polymer (2) and the primer (4), and/or polymer brushes (8) melting or softening and entangling with melted or softened polymer (2) so that the solid part (1) and the polymer (2) remain joined after cooling. The obtained strength of the bonding between the solid part (1) and the polymer (2) is significantly higher than if the same materials are joined with conventional methods not comprising the establishment of a primer layer (4).
