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.

A limb for a breathing circuit manufactured from very thin walled polymer materials has an elongate axial reinforcing spine lying freely inside the conduit and fixed to each end connector. The spine is laterally compliant but axially stiff. The spine provides resistance to tensile and compressive loads on the conduit, including that induced by prevailing internal pressures.

Disclosed herein is a device for producing composite components including at least one wound fiber reinforced polymer layer, including: a support with a first holding device and a second holding device for mounting a liner in between, where the first and the second holding device are such that the liner can rotate around a central rotation axis which extends through the first holding device and the second holding device, and at least two movable arms for feeding a fiber structure, where the support is established such that the liner can be moved axially parallel to the central rotation axis and each movable arm for feeding the fiber structure can be moved perpendicular to the central rotation axis. Further disclosed herein is a process for producing composite components using the device.

The disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or may be employed for other medical uses.

A filament winding device includes: a helical winder which winds a fiber bundle around a liner; a bobbin supporting shaft which rotatably supports a bobbin for providing the fiber bundle to the helical winder and a bobbin different from the bobbin in a state in which winding-initiation ends of the fiber bundle wound around the bobbin and winding-termination ends of the fiber bundle wound around the bobbin connect to each other; and a fiber bundle storage unit. The fiber bundle storage unit has a stopper which can switch the fiber bundle storage unit between a storage state in which the fiber bundle is stored in the fiber bundle storage unit and a storage-released state in which the fiber bundle has been released from storage in the fiber bundle storage unit and the fiber bundle is supplied from the fiber bundle storage unit to the helical winding unit.

There is provided a high-pressure tank manufacturing method that ensures a shorten heating period compared with a conventional one and eliminates a need for taking out a material for heating after heating. A high-pressure tank manufacturing method includes: disposing a conductive heating material on an outer periphery of a resin liner; winding a conductive fiber with which thermosetting resin is impregnated around the outer periphery of the resin liner on which the heating material is disposed; and heating the heating material and the fiber on the outer periphery of the resin liner by induction heating to harden the thermosetting resin.
