Abstract: In a process for manufacturing composite rotor blades comprising a blade(10) and a foot(11) laminates(5,6,7) of polymer composite are placed in a multi-part tool(2,3,4), heated and pressed. The moulded blade is removed from the tool after cooling to below the matrix glass transition temperature.

Abstract: This bladed (1) wheel (18) is constructed essentially from sections comprising blades (10) and roots (11). The sections are made of polymer composite. In novel design, the adjacent roots and/or the blades overlap. Preferably the wheel is directly bonded to a shaft (13). The roots may be connected to a hub (12) with a retaining- or support ring. The polymer composite has a thermoplastic or duroplastic matrix. Carbon fibres form the reinforcement.

Abstract: The device consists of a self-supporting stiffener belt (14), which is located in a ring around the ends (4) of the rotating blades (1). The belt has a U-shaped profile, open towards the flow-defining wall of the turbine housing (6). The belt has bores (23), containing radially movable fasteners (12) to connect the belt to the blade ends. The U-profile of the belt contains a metal strip (15) enclosed by a plastics strip (16). Stiffener belt, metal strip, and fasteners consist of titanium alloy, the plastics strip consists of a thermoplastic material with carbon fibre reinforcements.
