Embodiments of the invention relate to the construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material is provided in the inner layer.

Methods include providing a plurality fabric material layers, applying a plastisol layer between each fabric material layer forming plurality fabric material layers thereby creating a belt carcass, pressing the fabric material layers together with the plastisol layer(s) at a pressure of at least 5 psi to produce a preformed fabric carcass while heating the preformed fabric carcass while heating the preformed fabric carcass to a temperature which is within the range of about 360 F. to about 450 F. for a period of at least 6 minutes, disposing a thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, pressing the thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, and splicing opposing distal ends of the belt in a stepped splice configuration. The layers may be devoid of covering strips of lattice fabric disposed adjacent an abutment of any proximally positioned fabric layer.

A method for manufacturing an endless belt includes: coating a depression that is formed between both belt longitudinal ends of surface rubber of a belt and to which an adhesion processing material is attached, with at least one layer of unvulcanized rubber sheet; and vulcanizing the unvulcanized rubber sheet to bond the unvulcanized rubber sheet to the surface rubber, in which A is less than B, where A is a belt longitudinal distance between a belt longitudinal edge of an interface of the unvulcanized rubber sheet and the adhesion processing material and a belt longitudinal edge of the depression, and B is a belt longitudinal distance between a belt longitudinal edge of an area to which the adhesion processing material is attached and the belt longitudinal edge of the depression.

A method for fabricating a composite material assembly includes: a) providing an assembly system, b) laying down a first module on a first mold, the first module comprising a first laminate covering a first laminate support structure, c) laying down a second module on a second mold, the second module comprising a second laminate covering a second laminate support structure and extending over the at least one removable insert, d) removing the at least one removable insert from the second mold, and e) assembling the first mold with the second mold while overlapping a section of the second laminate extending over the at least one removable insert over the first laminate.

A system and method for fabricating a composite material assembly. The components of the assembly originate from more than one mold while providing curing or solidifying under heat and vacuum in one step only, preferably with a composite material in a pre-preg form which does not require autoclave treatment. A removable insert is removed from a second mold prior to assembly of a first mold to the second mold. A section of a laminate extending over the removable insert overlaps over an adjacent laminate after closing and assembly of the first mold onto the second mold.

A friction welding method for fastening a connection bushing, such as a threaded bushing for example, in a housing. In order to improve the quality of the connection, the connection bushing is attached to the housing using a friction welding element. The friction welding element consists of the connection bushing, on which a friction welding shell with a radially outer friction welding contour is formed or molded. Connecting and sealing portions are produced between the friction welding element and the housing during the friction welding process by means of a special design of the friction welding contour.

A composite reinforcement component for an aircraft or spacecraft, including a first element assembly aligned in a first extension plane, and a second element assembly aligned in a second, perpendicular, extension plane, the second element assembly intersecting the first element assembly at an intersection of the first and second extension planes. The first and second element assembly each have a pair of staggered comb components. Each comb component includes a base and a plurality of rectangular protrusions extending coplanar from the extension planes of the respective element assembly. The rectangular protrusions form comb teeth of one comb component which are overlapping with comb teeth of the other comb component of the pairs of comb components. The comb teeth of the first element assembly are offset along the intersection by a single comb tooth width with respect to the comb teeth of the second element assembly.

Sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer thereof may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each include a semi-crystalline thermoplastic material. A reinforcement material may be provided in the inner liner layer. In one embodiment the sealing material is injected into the sealing area. In another embodiment the sealing material is provided in the form of meltable ring which fits into the sealing area before fitting of the coupling member, and is activated by an induction heater to effect the sealed connection.
