A composite fluid transfer conduit. The conduit includes a first end portion, a second end portion and a main body portion between the first and second end portions. At least one of the first and second end portions is an end portion comprising a circumferential groove in a radially outer surface of the fluid transfer conduit, an axial end face, and a transition surface between the axial end face and the circumferential groove. The transition surface is configured such that, for any angle of impact of the end portion with a planar impact surface, a resultant impact force on the end portion is directed away from the circumferential groove.

Composite fluid transfer conduit

A method of manufacturing a monolithic fiber-reinforced polymer composite component is provided. The method comprises providing a mould comprising a main cavity and at least one additional cavity that extends from the main cavity; introducing a polymer matrix material containing chopped fiber reinforcement into the mould to fill the main cavity and the at least one additional cavity to form a monolithic fiber-reinforced polymer composite component with a main portion formed in the main cavity and at least one raised feature formed in the additional cavity and extending from a surface plane of said main portion. The at least one raised feature is arranged to incur visually perceptible damage when the component is subject to an impact with an energy above a predetermined impact energy threshold and to resist an impact with an energy below the predetermined impact energy threshold.

Method of manufacturing a composite component

A method of manufacturing a composite (e.g. fibre-reinforced polymer) connector comprises: manufacturing a tubular hub portion which extends substantially parallel to a central axis C, the hub portion comprising a thermoplastic polymer reinforced with continuous, circumferentially-oriented fibre reinforcement; placing the hub portion into a mould featuring at least one cavity; and introducing polymer into the mould so as to fill the at least one cavity to form a flange portion around the hub portion.

Composite connectors and methods of manufacturing the same

A fiber-reinforced polymer composite component formed from a polymer matrix material containing fiber reinforcement. The component comprises a main portion and at least one raised feature extending from a surface plane s of said main portion. The at least one raised feature is arranged to incur visually perceptible damage when the component is subject to an impact with an energy above a predetermined impact energy threshold and to resist an impact with an energy below the predetermined impact energy threshold.

Composite components with impact detection

A method of manufacturing a connector for a fluid transfer conduit comprises: providing a first mould section comprising a hub-moulding portion which extends substantially parallel to a central axis C and a flange-moulding portion which extends from the hub-moulding portion at an angle to the central axis C; introducing fiber-reinforcement to the first mould section such that continuous circumferentially-oriented fiber-reinforcement lies in the hub-moulding portion, and continuous longitudinally-oriented fiber reinforcement extends from the hub-moulding portion into the flange-moulding portion; applying a second mould section over the first mould section to form a complete mould in which the fiber-reinforcement is confined; and introducing a polymer to the complete mould such that it permeates through the fiber-reinforcement to form a fiber-reinforced polymer connector; and extracting the connector from the mould.

An isolator includes a first fluid-carrying member and a second fluid-carrying member; and a resistive, semi-conductive or non-conductive component located between the first and the second fluid-carrying member. The component conveys fluid flowing from the first fluid-carrying member to the second fluid-carrying member. The isolator further has a reinforcing composite encircling the first fluid-carrying member, the second fluid-carrying member and the component. The reinforcing composite having first fibers extending at an angle of between &#x2212;30 degrees and +30 degrees to a longitudinal axis (A-A) of the resistive, semi-conductive or non-conductive component; second fibers interwoven with the first fibers and extending around the first fluid-carrying member, the second fluid-carrying member and the component at an angle of between +60 degrees and +90 degrees and/or between &#x2212;60 degrees and &#x2212;90 degrees to the longitudinal axis (A-A); and a resin.

Electrical isolator

An electrical isolator includes comprising: a first fluid-carrying member a second fluid-carrying member spaced apart from the first fluid-carrying member to form a gap; a resistive, semi-conductive or non-conductive component extending across the gap and bonded to the first and second fluid-carrying members so as to provide a fluid tight seal between the first fluid-carrying member and the resistive, semi-conductive or non-conductive component and between the second fluid-carrying member and the resistive, semi-conductive or non-conductive component. The isolator also includes a reinforcing composite encircling the first fluid-carrying member, the second fluid-carrying member and the resistive, semi-conductive or non-conductive component.

A fluid transfer conduit comprising: an electrically conductive tube of fibre reinforced polymer composite material which has an electrically conductive outer surface and an electrically conductive inner surface; and on at least one axial end of said conduit, a non-electrically-conductive band formed on either the outer surface or the inner surface of the electrically conductive tube. Forming a non-electrically conductive band on the end of the conduit electrically isolates the electrically conductive outer surface of the conduit from the electrically conductive metal socket into which it is to be inserted.
