    Abstract: A golf club head having a composite face insert attached to a metallic body is provided. The club head preferably has a volume of at least 200 cc and provides superior durability and club performance. The face insert includes prepreg plies having a fiber areal weight (FAW) of less than 100 g/m2. The face insert preferably has a thickness less than 4 mm and a mass at least 10 grams less than an insert of equivalent volume formed of the metallic material of the body of the club head. A metallic cap with a peripheral rim is also provided to protect the ends of the composite material of the face insert. Related methods of manufacturing and alternative materials are disclosed. The resin content of the prepreg plies can be controlled through management of the timing and environment in which the resultant prepreg plies are cured and soaked.
