摘要： The propeller shaft comprises a transmission shaft 10 consisting of a hollow metal tube 11 with excellent torque transmissibility and a composite material prepregs 12 having higher specific stiffness than a metal material and stacked to the inner surface of the metal tube, and metal yokes 40 mounted on both ends of the transmission shaft and assembled with other devices. The composite material prepregs is co-cure bonded while applying an axial compressive preload to the transmission shaft and creating a vacuum in a space between a vacuum bag inserted in the transmission shaft and the composite material prepregs of the transmission shaft. Teeth 43 or embossments 44, and adhesive-retaining grooves 45 are formed on inner surfaces of the metal yokes, so the transmission shaft is desirably compression-fitted into the metal yokes. Accordingly, the propeller shaft has advantages of securing improved impact, abrasion, and water resistance.

摘要： A method of repairing or reinforcing worn-out underground buried drainpipes by a resin transfer molding process using both flexible tubes and bagging films is disclosed. In the method of this invention, a reinforcement is primarily inserted into a desired position within a target worn-out drainpipe buried underground. The reinforcement consists of a fiber preform internally having a flexible tube, such as a silicon tube, axially extending along the central axis of the preform and wrapped with an adhesive-coated flexible film as a bagging film to provide protection from sewage or underground water. The flexible tube is, thereafter, expanded to bring the fiber preform into close contact with the interior surface of the target drainpipe. The opposite ends of the reinforcement are sealed with two lids. Thereafter, thermosetting resin is transferred into the fiber preform, thus allowing the fiber preform to be impregnated with the thermosetting resin. The impregnated resin is, thereafter, cured to shape the fiber preform as desired, thus repairing and reinforcing the target drainpipe.

摘要： A hybrid shaft adapted to be used as a drive shaft of an automobile transmission system comprises a unitary cylindrical hybrid stem formed from a metal tube and a composite material layer adhered to the metal tube. The metal tube provides torque-transmission strength to the hybrid shaft while the composite material layer increases a specific modulus of the hybrid shaft. The hybrid shaft is produced by stacking a composite material layer on a metal tube, putting a thermal shrinkage tube on the composite material layer, and co-curing the metal tube and the composite material layer while exerting a longitudinal compression force on the metal tube to prevent it from being thermally expanded.
