摘要:
Composite strip, and methods for forming a junction between two conduits. A composite strip (10) which extends in a main direction (P) between first and second ends (10a, 10b) and comprises a main strip (11) comprising first fibres (11a) embedded in a matrix (11b). The first fibres are made of carbon, an electroconductive material, and the matrix consists of at least one polymer. The composite strip (10) also comprises a junction layer (17) formed from an electroconductive junction material. The junction layer is arranged on the main strip, only at the ends thereof.

The invention relates to an electric heating device comprising a support (2) and a heating layer (3) made of a carbon fibre composite arranged on the support and connected to an electrical power supply for heating the device. The volume of the heating layer (3) comprises a part consisting of an electroconductive circuit (4) which extends along at least one continuous line, and a non-electroconductive insulation part (5) which fills the rest of the volume of the heating layer.

The invention relates to a method for forming an electrical connection in a conduit for transporting a fluid. Said conduit (1) comprises an inner hollow tube (2) and a heating layer (4) comprising first carbon fibres. Said method comprises the following steps: a step (101) of groove formation wherein a groove (6) is made in the heating layer; a step (202) of producing an interface wherein a junction layer (7) is deposited on the heating layer of the groove; and a positioning step (103) wherein a connecting strip (8) comprising second fibres formed from a second electroconductive material is rolled up on the junction layer.
