The integrated heat exchangers may comprise a solid or fluidic heat exchanger material which is able to transfer heat around the structure. The heat exchanger may be selected to transfer excess heat away from the device or transfer heat into the device. The device comprising at least one fibre ply, wherein said ply is substantially encapsulated in a binder matrix to form a fibre reinforced polymer composite, wherein said device comprises at least one elongate void which comprises at least one heat exchanging medium.
Abstract:
A method for electroless metal deposition on a surface in a finely dimensioned space (e.g. the bore of a hollow fibre) comprises introducing into said space an electroless plating solution that has a nil or relatively low plating rate at normal room temperature, and there after heating said structure to an elevated temperature for a period sufficient to cause metal to plate on the wall surface. The steps of introducing and heating may be repeated as necessary to build up a required thickness.
Abstract:
Composite structural components are disclosed that include electrically conducting fibres providing signal power paths to electrical components disposed on or adjacent the material. The signal paths may therefore be embedded in the structural component. Also disclosed is a flexible or drapable fabric containing electrically conducting fibres for similar purposes, and materials for making up said structure and fabrics and methods for the production thereof.
Abstract:
A detector for detecting ionising radiation comprises a scintillator (10) selected to emit light in response to incidence thereon of radiation to be detected, at least one detector (16) for detecting said emitted light, and at least one optical waveguide (12) for transmitting said emitted light to said detector (16). The optical waveguide typically comprises a flexible solid or hollow fibre that can be incorporated into a flexible mat or into a fibre-reinforced structure, so that the detector is integrated therewith.

Abstract:
Composite structural components are disclosed that include electrically conducting fibres (42) providing multiple signal or paths to electrical components disposed on or adjacent the material. The signal paths may therefore be embedded in the structural component as an intrinsic reinforcing element. Also disclosed are materials for making up said structure and fabrics and methods for the production thereof.
