摘要： A method of rivet bonding a workpiece stack-up that includes one or more polymer composite workpieces, such as carbon fiber composite workpieces, involves several steps. In one step, adhesive is applied to a surface of the workpiece stack-up. In another step, workpieces—including the polymer composite workpiece(s)—are brought together. In yet another step the adhesive is partially or more cured. A rivet is installed through the workpiece stack-up and through the adhesive in another step. The method strengthens the resulting rivet-bonded joint by minimizing or altogether precluding fracture, cracking, and/or delamination thereat.

摘要： An assembly and method for minimizing an overlap of a composite member riveted to another member includes a first member having a first overlap area and a second member having a second overlap area. The overlap areas of the first and second members are in direct contact, thereby forming an overlapped region. The overlapped region may be thicker than the sum of the individual members. The second member includes an end defining a projection in the overlapped region. The rivet is disposed through the first member and at least partially through the second member in the projection, thereby interlocking the second member to the first member. The projections include a curved symmetrical body defining an apex. The rivet extends through the body such that a line extending from the center axis of the rivet is perpendicular to a tangent extending through the apex of the projection.

摘要： A method of laser welding a workpiece stack-up includes directing a laser beam at a top surface of a first metal workpiece to form a key-hole that entirely penetrates the workpiece stack-up, including an underlying second metal workpiece, so that the keyhole reaches a bottom surface of the second metal workpiece. A zone of negative pressure established under the bottom surface of the second metal workpiece extracts vapors that are produced by the laser beam. The vapors, in particular, are extracted from the bottom surface of the second metal workpiece through the keyhole. A bottom workpiece holder that supports the bottom metal workpiece during laser welding may be constructed to establish the zone of negative pressure.

摘要： A device for joining thermoplastic workpieces includes an ultrasonic welder including an ultrasonic transducer, a booster and a horn having a welding tip. A clamping mechanism attaches to the ultrasonic welder and includes an upper frame coupled to a boot. The welding tip of the horn of the ultrasonic welder projects into an aperture in the boot of the clamping mechanism. The clamping mechanism exerts a clamping force on the workpieces that differs from a welding force exerted on the workpieces by the ultrasonic welder when the ultrasonic welder is operating to join the thermoplastic workpieces.
