Abstract: A functionalized adhesive and systems and methods employing the same are disclosed. The functionalized adhesive is configured to form an adhesive joint between a first substrate and a second substrate. The functionalized adhesive comprises a neat adhesive selected to have a bonding strength above a predetermined bonding threshold and a filler selectively dispersed within the neat adhesive. The filler is selected to modify electrical properties of the neat adhesive such that the functionalized adhesive is electrically conductive with a tailored resistivity and such that a resistance of the adhesive joint is greater than a resistance of the first substrate and the second substrate.

Abstract: A method of manufacturing a long fiber reinforced thermoplastic filament includes disposing a mixture of fibrous material and thermoplastic material into a hopper of an extruder device and introducing the mixture into the extruder and through an extensional flow die to preserve longer fiber lengths. From the extensional flow die the mixture is passed through a drawing die to create the long fiber reinforced filament.

Abstract: A system for transporting a non-Newtonian material. The system includes a storage container configured to store the non-Newtonian material and a dispensing system configured to dispense the non-Newtonian material. A conduit connects the storage container to the dispensing system. The conduit is configured to transport the non-Newtonian material from the storage container to the dispensing system. A pump is configured to pump the non-Newtonian material out of the storage container and through the conduit to the dispensing system. A hanger is configured to support the conduit from a support structure. An acoustic wave generator is along the conduit configured to impart acoustical shear agitation to the non-Newtonian material to reduce viscosity of the non-Newtonian material.

Abstract: A fused filament deposition head is employed for depositing filament materials on workpieces to join the workpieces together. The workpieces can be of an automotive application, aerospace application, or something else. The fused filament deposition head, in an example, has a feed end, a dispensing end, and a heater. The feed end introduces more than one filament in the fused filament deposition head, as demanded in the larger application. The dispensing end delivers materials of the filaments to the underlying workpieces. The materials are delivered together. The heater serves to heat the filaments as they travel through the fused filament deposition head. The filaments can include a filament having a core portion of liquid-crystal polymer material.

Abstract: An amalgamation plate for joining a first component to a second component has a planar body configured to be placed between the first component and the second component, and a plurality of first protrusions extending from a first side of the planar body. The first protrusions are radially dispersed from an axis of the planar body, and are configured to be embedded within either the first component and the second component. The amalgamation plate may also have a plurality of second protrusions extending from a second side, opposite the first side, of the planar body. The second protrusions are radially dispersed from the axis, and are configured to be embedded within the other of the first component and the second component via application of force substantially along the axis. The first protrusions and the second protrusions may be radially symmetric about the axis of the planar body.

Abstract: A composite fusion filament is disclosed that includes a polymer encasement and one or more mesogenic reinforcement bodies contained within the polymer encasement. The polymer encasement is comprised of a thermoplastic polymer, which has a melting temperature, and each of the one or more mesogenic reinforcement bodies is comprised of a thermotropic liquid crystal polymer, which has a clearing temperature. The melting temperature of the thermoplastic polymer included in the polymer encasement is less than the clearing temperature of the thermotropic liquid crystal polymer included in the one or more mesogenic reinforcement bodies. Additionally, the thermotropic liquid crystal polymer of each mesogenic reinforcement body has a plurality of organized crystalline fibrils that are aligned lengthwise along a longitudinal axis of the polymer encasement. A method of using the composite fusion filament to form a bond with a substrate that includes a thermoplastic polymer is also disclosed.

Abstract: A method of joining workpieces includes the steps of bringing a first workpiece and a second workpiece together, induction heating a susceptor material, and pressing the workpieces together. Each workpiece may include a thermoplastic material, and the workpieces are brought together at a joint interface so that a protrusion of the first workpiece is aligned with a receptacle of the second workpiece. The susceptor material is in contact with the thermoplastic material of the first workpiece during heating such that the thermoplastic material of the first workpiece softens. The step of pressing is performed while the thermoplastic material of the first workpiece is softened, thereby reshaping the first workpiece where the susceptor material is in contact with the thermoplastic material of the first workpiece. The protrusion is deformed to form an interlock with the receptacle at the joint interface.
