A system comprising a pipe and at least one fitting, wherein the pipe is made essentially of a thermoplastic, fiber-reinforced composite material, and the fitting is made essentially of titanium or a titanium alloy, and the pipe and the fitting are connected in a fluid-tight manner

A manufacturing method for manufacturing a welded thermoplastic composite and honeycomb core structure is provided. A thermoplastic composite and honeycomb structure is generated by positioning a first thermoplastic composite skin on a support structure, positioning a first thermoplastic film over the first thermoplastic composite skin, positioning a honeycomb core over the first thermoplastic film, positioning a second thermoplastic film is positioned over the honeycomb core, and positioning a second thermoplastic composite skin over the second thermoplastic film. The second thermoplastic composite skin is ultrasonically welded to the honeycomb core. The thermoplastic composite and honeycomb structure is then flipped over, and the first thermoplastic composite skin is then ultrasonically welded to the honeycomb core.

A method of bonding a composite vane to at least one support. The method includes positioning an end of a vane within a support, causing an adhesive to flow between the vane and the support from an inlet to an outlet, and reversing the flow of adhesive from the outlet towards the inlet.

A composite structure and methods of forming are presented. A composite structure comprises: structural supports and a structural skin formed by a plurality of composite panels fastened to the structural supports. Each composite panel of the plurality of composite panels comprises a first titanium end; a second titanium end; and a composite skin joined to and extending between the first titanium end and the second titanium end.

Metal to composite joints and methods of forming are presented. A metal to composite joint for a platform comprises two metal structural components forming a portion of a first surface and a portion of a second surface of the metal to composite joint; and a dividing set of composite plies between the two metal structural components providing an escape path for volatiles between the two metal structural components.

A method of bonding a composite vane to at least one support. The method includes positioning an end of a vane within a support, causing an adhesive to flow between the vane and the support from an inlet to an outlet, and reversing the flow of adhesive from the outlet towards the inlet.

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 golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a multi-material striking face portion that is made out of a backing layer having a frontal pocket, made out of titanium, and an insert, made out of a composite material, adapted to be inserted into the frontal pocket. The frontal pocket and the insert could have complementary dovetail shaped undercut features to create a mechanical bond between these two components. The insert may be bonded to the frontal pocket using an adhesive impregnated within a glass fiber weave.
