A multi-material joint and a method of making thereof. The multi-material joint includes a first member comprising a first metal or metal alloy that is secured to a second member comprising a second metal or metal alloy that is different than the first metal or metal alloy. A sealant is positioned between the first member and the second member that galvanically insulates the first member from the second member. The sealant comprises a liquid elastomer and a foaming agent.

A method of bonding a second object to a first object includes: providing the first object having a thermoplastic liquefiable material in a solid state; providing the second object having a surface portion that has a coupling structure with an undercut, so that the second object is capable of making a positive-fit connection with the first object; pressing the second object against the first object with a tool that is in physical contact with a coupling-in structure of the second object while mechanical vibrations are coupled into the tool; continuing to press and couple vibrations into the tool until a flow portion of the thermoplastic material of the first object is liquefied and flows into the coupling structures of the second object; and letting the thermoplastic material re-solidify to yield a positive-fit connection between the first and second objects by the re-solidified flow portion interpenetrating the coupling structures.

Methods for fastening two fiber composite parts to each other with a fastener that includes electroactive polymer material. The parts have an opening within an inner circumferential surface. Fibers protrude from the inner circumferential surface into the opening and interlock with chains of micrograins of the electroactive polymer material. The fastener may switch between an activated state and a deactivated state and in the deactivated state, the fastener engages the exposed fibers.

This invention relates to an assembly of regions (10a, 10b) of composite parts (2a, 2b) with thermoplastic matrix, including a plurality of riveting points along regions (10a, 10) of the parts that overlap through the superposition of two faces (12a, 12b) of these regions (10a, 10b) which are positioned facing one another, each region (10a, 10b) having another, opposite, face (11a, 11b) which remains visible with the part (2a, 2b). The riveting is performed using assembly ties (6) made of thermoplastic resin-based composite material compatible with the material of the parts (2a, 2b). These ties (6), which are made up at least in part of a stitch of backstitch produced using a filament of a material selected from a fiber coated with aramid resin, a carbon fiber and a glass fiber, are embedded in said regions (10a, 10b) and passing right through the same with an orientation comprised between 30 and 90 with respect to their faces (11a, 11b; 12a, 12b).

A method for joining two objects by anchoring an insert portion provided on a first object in an opening provided on a second object. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. During the step of inserting the insert portion in the opening and/or during anchorage a clamping force is applied to opposing surfaces of the second object to prevent the second object from cracking or bulging.

Provided is a thermal caulking method of melting, at one time, a plurality of bosses 33 of a second member 30 protruding toward an inner circumferential surface of a conical hollow portion 11 of a first member 10 while being fitted to a plurality of holes 132 provided in the inner circumferential surface of the hollow portion 11 of the first member 10 having the substantially conical hollow portion 11 so that the plurality of bosses are joined to the first member 10, in which the plurality of bosses 33 are melted at one time by using a heat chip 51 having a continuous shape in the circumferential direction of the hollow portion 11 along the inner circumferential surface and are joined to the first member 10 while the adjacent melted bosses 33 are connected to each other.

The present invention is directed to the use of all improve,d hydrocarbon adsorption system for the treatment of evaporative emissions from a motor vehicle. More specifically, the system includes one or more hydrocarbon adsorption elements being housed within a frame, the frame being permanently affixed within the air intake housing of engine.

A process for the marking of a film or a bag, which consists of a film at least in sections, wherein the film or the bag comprises a medical product or is provisioned or prepared for the uptake of such, wherein the process comprises connecting a film strip with, in, to and/or on the film, wherein the film strip carries information for marking the medical product.

A method for connecting two aircraft components composed of thermoplastic composite material by a rivet. The two aircraft components are arranged, in sections, areally on one another, before bores in the two aircraft components are expanded by a mandrel element such that the bores, after the expansion, form one continuous bore for receiving the rivet. Here, the two aircraft components are locally warmed by the mandrel element such that, during the expansion of the bores, the components are thermoplastically deformed. The mandrel element is inserted through the first bore into the second bore. The rivet is introduced into the continuous bore. A system for carrying out the method is also disclosed.
