<p>An electrically powered heating element (1, 2) for a propeller blade is made up of a mat of fibres having at least surfaces which are electrically conductive. The mat can have a perforated backing to which it is fixed by adhesive. Methods of producing the heating element and fixing the heating element to a propeller blade involve a curing step for bonding the mat and backing using the adhesive.</p> |
