摘要： A tie rod suitable for use with known concrete forming systems is constructed from a non-metal fiber, such as fiberglass, that is wound about a pair of opposed thimble elements. The resultant tie rod is as strong as a metal tie rod without the drawbacks of conventional metal tie rods. Each of the thimble elements has a main body having a channel formed in an outer surface of the main body, and the fiberglass fiber is disposed within the channel when wound thereabout.

摘要： A method of manufacturing a reinforced pipe (7) comprising: wrapping a pipe (1) in reinforcing tape (2) to form a wrapped pipe having an outer circumference consisting of a first circumferential portion (4) and a second circumferential portion (6); and passing the first circumferential portion (4) over one or more heating elements (3) to fuse the reinforcing tape (2) of said first circumferential portion (4); wherein: the first circumferential portion (4) is between 1% and 50% of the outer circumference; and the second circumferential portion (6) is not passed over a heating element (3) and is not fused. The method is advantageous in that it can provide reinforced pipes (7) in a simpler and cheaper way because it is not essential that the entirety of the outer circumference of the reinforced pipe (7) is fused. A reinforced pipe (7) produced according to the method of the present invention is also provided.

摘要： A method for manufacturing a composite pressurized-fluid vessel including winding a first polyolefin resin-based tape thereby forming a first layer of the vessel, depositing an intermediate second layer on the first layer, consisting of a material having variable permeability properties depending on the temperature and permeability below a pre-determined temperature threshold and non-permeability above the temperature threshold, winding a second resin-based tape on the intermediate second layer thereby forming a third layer, and cooling the intermediate second layer to a temperature below the temperature threshold while the first and third layers are each kept at a temperature above the melting temperature of their resin. Wherein the tape forming the third layer is based on a different resin from the first layer and during the step of depositing the intermediate second layer.

摘要： The invention relates to a method and a device for manufacturing a pipe shell from an insulating material by means of which the cycle times can be further reduced while the quality of the pipe shell is simultaneously improved, by at least one web (29) of the insulating material which is provided with a binding agent being wound around a core (19) by means of at least two opposing belts (12, 13) which wrap around the core (19) partially. The method steps are characterized in that the at least one wound-up web (32) of insulating material is removed in a radial direction of the core (19) which is, however, not opposite to the direction in which the at least one web (29) of insulating material was fed by the one belt (12), especially by the wound-up web (32) being discharged through the same belt (12).

摘要： Methods and systems are disclosed for encasing various structures with a seamless continuous sleeve, where the presence of existing supports does not allow slipping a sleeve over the structure. In these methods strips of fabrics smeared with or saturated by resin are helically or non-helically wrapped or placed around desired shape mandrels that are located around a support of the structure. As the resin is partially cured, a portion of the sleeve segment is moved away from the mandrel, leaving the rest of the sleeve on the mandrel to be attached to the next will-be-fabricated sleeve segment. The process will continue as many times as needed to create a sleeve of a desired length. In various embodiments the strength of the sleeves varies at different locations. In some embodiments the gaps between the sleeves and the structures are filled with gas, liquid, solid, or any other materials.
