  • Method for manufacturing metal/composite hybrid wheel for vehicle and metal/composite hybrid wheel manufactured by the same
    Patent number: 9259882
    Abstract: The present invention provides a method for manufacturing a metal/composite hybrid wheel for a vehicle by molding an inner rim of a composite material by compression and, at the same time, bonding an outer rim of a metal material to the inner rim to induce compressive residual stress in the bonding area by a difference in thermal expansion coefficient between the outer rim and the inner rim, thereby increasing the adhesive strength of the bonding area and the durability of the wheel. The present invention further provides a metal/composite hybrid wheel for a vehicle manufactured by the method.
