Abstract
Laminated striking face inserts for golf clubs are characterized by explosion bonding of the layers of the laminate. The outer layers are of a substantially high strength and density material and the center layer is of relatively lower strength and density material. Explosion bonding results in a laminated face plate or insert in which the yield strength of the laminate is similar to the full strength characteristics of the materials used in the laminate.
Claims12
A laminated striking face plate for a golf club head, comprising
- (a) a first outer layer having an outer surface defining a striking face of the golf club head;
- and
- (b) an inner layer having a lower yield strength than said first outer layer;
- (c) said inner and outer layers being joined by an explosion bond, whereby the yield strength of said face plate is increased relative to the yield strength of the layers..
A method for manufacturing a laminated striking face plate for a golf club head, comprising the step of explosion bonding a first outer layer to an inner layer, said outer layer having higher yield strength than said inner layer and having an outer surface defining a striking face of the golf club head.
