Process for producing a high-strength, rotationally-symmetrical component by appending short fibers of glass, carbon or aramid in an organic solvent, and depositing the fiber material in a rotating sieve-like receptacle through a radially movable nozzle. The produced preform is impregnated with a matrix of resin and hardener and pressed into its final shape.

Process for the manufacture of rotationally-symmetrical components from

A structural component is made by providing a main body and applying fibre material to the body so as to adjust the coefficient of thermal expansion and/or the modulus of elasticity of the main body. If the main body is made by molding, the fibre material may be embedded in the main body while the molding material is still soft. The fibre material may be loose long fibres adhesively secured to the main body. The fibre material may be a layer having a fibre orientation arranged in the direction in which stress is experienced by the structural component and/or the direction in which expansion of the structural component is to be resisted. Several layers of fibre material may be applied to the main body with the fibre orientation of different layers being in different directions.

Method of manufacturing structural components

A rotor wheel including a hub in the form of a thin-walled shell. Rotor blades are arranged in an annular pattern around the axis of the hub, each blade having at least one blade root formed with a hole. A pin extends through the hole in each blade root, and at least one retaining ring coaxial with the hub axis surrounds all the pins and absorbs radial forces produced by the blades on the pins when the rotor wheel rotates. The retaining rings and blades are fixed against axial and circumferential movement with respect to the hub. A segment between each pin and retaining ring distributes the forces of the pin to the retaining ring. The pins are mounted for radial movement with respect to the hub, and one of the mounting parts for said pins may be detachable from the hub. The hub may be dish shaped, and the pins secured at only one end to the peripheral wall of the hub, that wall having axial slots so that it may expand radially.
