摘要： A method for fabricating fiber-reinforced composite structures, including centrifuge rotors, by resin transfer molding (RTM) is disclosed. The method involves loading reinforcing fibers into a mold and then injecting resin into the mold to coat the fibers to form the composite structure. Two types of reinforcing fibers are used—fabric preforms at the surfaces of the structure and chopped fibers at the interior of the structure. Also disclosed is a fiber-reinforced composite structure comprising a skin layer of reinforcing fabric, chopped fibers distributed throughout the interior of the structure, and epoxy resin that binds the fabric and chopped fibers together into a fiber-reinforced composite structure. The resin transfer molding method is especially useful for fabricating composite centrifuge rotors.
