ROTATING STRENGTH OF LAMINATED COMPOSITE DISCS.

The rotating strength of a circumferentially fiber-reinforced disc is limited by the radial strength of disc material. To increase the radial strength of the disc additional radial fiber-reinforcement, fiber-reinforcement tangential to the inner hole, and lamination-reinforcement with in-plane isotropy of discs are studied theoretically and experimentally. A method of laminating-reinforcement of a circumferentially fiber-reinforced disc is proposed.
