Abstract
A multi-material golf club head having an improved performance is disclosed. More specifically, the present invention relates to a multi-material golf club head having a metallic frontal portion and a lightweight aft portion with an addition of an internal ribbon support member. The lightweight aft portion could be formed of a multi-layered sandwich material with at least one layer having low damping properties. The present invention may also further be comprised of a weighting mechanism that is accessible via an opening in the lightweight after portion but connects directly to the metallic frontal portion to mitigate any of the structural integrity issues associated with installing weights in a lightweight portion of a golf club head.
