ABSTRACT:
In a hybrid leaf spring, an elongated primary leaf element is provided having a first modulus of elasticity, a tension surface, and a compression surface. At least one layer of composite material is substantially parallel to and bonded to the tension surface of the primary leaf element with at least a second layer of composite material bonded to the compression surface of the primary leaf. The primary leaf element can also include mounting eyes coupled to the ends of the primary leaf element for mounting the hybrid leaf spring to the frame of a vehicle. The hybrid leaf spring can also include multiple layers of composite material bonded to both the tension and compression surfaces of the primary leaf spring.
