Abstract
A composite elastomeric spring having a predetermined final shape and including a first member of elastomeric material having a first durometer hardness and a second member of elastomeric material having a second durometer hardness is disclosed. The second member has a predetermined initial shape complimentary to an initial shape of the first member. The second member is positioned adjacent and in circumferential surrounding relation relative to the first member to define a preform composite spring member. After the second member is positioned about the first member, a force is applied to the preform composite spring member sufficient to simultaneously compress the first member and the second member thereby permanently changing the initial shapes of the first member and second member are permanently changed from their respective predetermined initial shape such that the first and second members are thereafter maintained in captured relationship relative to each other. The force is then removed from and thereby allowing the preform composite spring to transmute to the final shape of the composite elastomeric spring.
