Rapidly rotating systems such as centrifuges are widely used in medicine and laboratories to efficiently separate different constituents of liquids. Rotors, which hold sample containers, are an essential part of centrifuges. Since they are subjected to extreme mechanical loads, rotors are one of a centrifuge’s core safety components. Their deficits served as the point of departure for the development of a novel manufacturing technology, which is based on carbon fiber-reinforced polymers (CFRP). Its supporting structure is entirely in the loading plane, thus enabling the rotor to absorb higher centrifugal forces while requiring the same amount of material. The new design concept for the load-bearing structure includes a geodesically molded annular support member. It transmits forces better than present products and increases rigidity. In order to eliminate the known problems with obtaining the necessary manufacturing quality of hollow fiber composite bodies, the authors developed the process of centrifugal infusion. Their proposed solution is based on generating higher gravitation forces, thus effectively eliminating detrimental gas pockets and simultaneously optimizing surface quality and impregnation.
