A random mat material including fiber bundles, said fiber bundles including fibers having an average fiber length of 5 to 100 mm, and having an average number N of fibers in the fiber bundle that satisfies: wherein D is the average diameter of fibers in the fiber bundle, expressed in micrometers, and the standard deviation SDof the number of fibers in a fiber bundle satisfies:1,000&#x3c;SD&#x3c;6,000wherein at an end of the fiber bundle, the number of the fibers in a fiber bundle becomes less from center to edge of the fiber bundle in a fiber direction.

Carbon fiber random mat and carbon fiber composite material

A composite strip which extends in a main direction between first and second ends and which comprises a main strip comprising first fibres embedded in a matrix. The first fibres are made of carbon, an electrically conducting material, and the matrix is made up of at least one polymer. The composite strip further comprises a junction layer formed of an electrically conducting junction material. The junction layer is placed on the main strip.

Composite strip, and methods for forming a junction between two conduits

An electrical heating device comprising a support and a heating layer made of carbon fibre composite on the support mid connected to an electrical power supply to warm the device. The heating layer has a volume which comprises an electrically conducting circuit part which extends along at least one continuous line, and an electrically non-conducting insulation part which fills the remainder of the volume of the heating layer.

Electric heating device

A method for forming an electrical connection in a pipe for transporting a fluid. The pipe comprises an internal hollow tube and a heating layer comprising first fibers made of carbon. There are performed a groove-formation step in which a groove is formed in the heating layer, an interface-preparation step in which a junction layer is placed on the heating layer of the groove, and a placement step in which a connection strip comprising second fibers formed of a second electrically conducting material is wound on the junction layer.
