Rotating Strength of Glass-Carbon Fiber-Reinforced Hybrid Composite Discs

抄録

The rotating strength of a circumferentially fiber-reinforced disc depends on the radial strength of disc material. Increasing the rotating strength of the disc of a given composite material requires to reduce the maximum radial stress as much as possible. The utilization of the hoop effect of the outer fiber layer of high elastic modulus, as a method of reducing the radial stress, is theoretically investigated and experimentally confirmed with glass-carbon fiber-reinforced hybrid discs. Applicability of the circumferentially fiber-reinforced disc as the flywheel is discussed.
