The heating device comprises electrically conducting longitudinal fibers extending substantially parallel to a leading edge of the aerofoil close to said leading edge, and means for electrically connecting the ends of the longitudinal conducting fibers to an electric power supply. The conducting fibers are grouped together in conducting rovings forming part of a hybrid fabric which furthermore includes a weft of electrically insulating fibers woven together and woven with the conducting rovings.

[ What is claimed is:] [1.] A method of making a device for heating an aerofoil, comprising the steps consisting of:providing a hybrid fabric, the warp of which being made of electrically conducting longitudinal fibers extending substantially parallel to a leading edge of the aerofoil in a region of the aerofoil including said leading edge, the conducting fibers being grouped together in conducting rovings and said hybrid fabric further including a weft of electrically insulating fibers woven together and woven with the conducting rovings,applying said hybrid fabric with a non polymerized resin on the aerofoil,curing said resin, andelectrically connecting the ends of the longitudinal conducting fibers to an electric power supply by electrical connection means.
