A bonded structure formed by bonding a first structure and a second structure at opposed bonding surfaces to form a microstructure or the like. At least one of the first structure and the second structure is formed of a resin composition including a polypropylene resin and a hydrogenated derivative of a block copolymer of the following general formula X-Y (X is a polymer block immiscible with the polypropylene resin, and Y is a conjugated diene elastomer polymer block). The bonding surfaces are ...

A method for producing carpeting of a type having pile yarns adhesively bonded to a backing which comprises providing a thin flexible core member having longitudinal and transverse axes, winding a continuous yarn around the core member in a direction perpendicular to the longitudinal axis so as to form a plurality of elongated loops conforming to the cross-sectional configuration of the core member, positioning the core member having the yarn wound thereon on a backing sheet so that the longitud...

A bonded wafer with a bond junction having low resistivity due to the low level of oxides at the bond junction. A plasma that removes native oxide layers from wafers is exposed to the wafers. The plasma forms a hydrophobic polymer seal on the wafers, inhibiting subsequent native oxide growth upon exposure to air. The polymer seal on the wafers to be bonded are pressed together and the wafers are annealed to form the bonded wafer in a non-oxidizing ambient. The bond junction formed is primarily s...

Fibres, fabrics made therefrom, or films of polyoxadiazoles, having an X-ray pattern which shows a single equatorial reflection corresponding to a spacing of 3.4A, are thermally bonded to themselves or other shaped articles by heating the contacting articles whilst under pressure to a temperature above the glass transition temperature of the polyoxadiazole.

A window for a support structure, such as a hull of a freighter or tanker or other large ship having clips, studs, glue and protective ultraviolet paint.

The processing time and energy efficiency of metal or composite bonding operations is improved by heating the lay-up preform of the structure in an induction heating press where energy goes primarily to heating the workpieces rather than to heating the tooling or being lost to the environment. The bonding process is especially beneficial for joining thermoplastic composites, but it also can be used with metals or thermosets. Preferential heating at the bondline is achieved by using shims to defi...

The invention contemplates a bonded assembly of plural parts having regions of channel-socket or telescoping fit with each other. One or more small apertures are provided to vent the overlap region of such fit, and the aperture assists in the pressurized liquid-phase introduction of hardenable bonding material. Depending upon the nature of the assembly or joint, (a) the parts may be fabricated to naturally and substantially close or dam the open annulus attributable to clearance between the over...

A hollow, heat-recoverable article 1, for enclosing objects such as electronic components etc. has a thermoplastic lining on its interior surface and includes a fusion bonded portion 2 in which different parts of the article have been brought together and bonded by fusion of the lining with substantially no welding of the heat-recoverable material forming the wall. The lining has a melting point that is higher than the recovery temperature of the article, thereby enabling subsequent recovery of ...

Thermally shock stable bonded solid materials are formed by mixing a solid mineral or inorganic material in an aqueous medium with a lignosulfonate, treating the aqueous medium with a metal ion- based complexing agent (such as lime), with application of heat sufficient to maintain the lignosulfonate in fluid form, so as to produce an intimate mix of saturated slaked lime with lignosulfonate and the mineral or inorganic material, and thoroughly mixing the resulting substantially dry material with...

The disclosure teaches a firmly joined composite applicable for joining objects of various shapes, including flat plates, curved plates, cylindrical objects, pipes and rods of circular and other than circular cross section. The joined composite is simple to prepare and can be made hermetically tight if desired.
