Publication number: 20110098130Abstract: The present disclosure pertains to composite articles, and in particular a composite face plate for a golf club-head, and methods for making the same. In certain embodiments, a composite face plate for a club-head is formed with a cross-sectional profile having a varying thickness. The face plate comprises a lay-up of multiple, composite prepreg plies. At least a portion of the plies comprise a plurality of elongated prepreg strips arranged in a predetermined criss-cross pattern in the lay-up. The prepreg strips create one or more areas of increased thickness where the strips overlap each other, thereby creating a desired profile for the plate. Metallic or polymer covers or cover layers can be used to define a striking surface.Type: ApplicationFiled: December 21, 2010Publication date: April 28, 2011Inventor: Bing-Ling Chao

Patent number: 7874938Abstract: The present disclosure pertains to composite articles, and in particular a composite face plate for a golf club-head, and methods for making the same. In certain embodiments, a composite face plate for a club-head comprises a lay-up of multiple, composite prepreg plies. The face plate can be made by first forming an oversized lay-up of multiple prepreg plies having a central portion and a sacrificial portion surrounding the central portion. The lay-up is at least partially cured in a mold under elevated pressure and heat. The lay-up is then removed from the mold and the sacrificial portion is removed from the central portion to form a composite part that is substantially free of defects.Type: GrantFiled: June 3, 2008Date of Patent: January 25, 2011Assignee: Taylor Made Golf Company, Inc.Inventor: Bing-Ling Chao

Patent number: 7862453Abstract: The invention prevents a resin member from being broken so as to improve durability. The invention provides a golf club head (1) in which at least a part of a crown portion (4) forming an upper surface of the head is formed by a resin member (FR) made of a fiber reinforced resin in which a fiber is oriented in a matrix resin. The resin member (FR) includes a one-way fiber reinforced resin layer in which the fiber is oriented in one direction, and a fiber intersection lamination portion which is laminated so as to differentiate a direction of the fiber. At least two one-way fiber reinforced resin layers which are adjacent in a thickness direction are intersected at an angle of 30 to 130 degrees of the fiber. Further, a compressive strength of the fiber of the one-way fiber reinforced resin layer which is arranged in an innermost side in the fiber intersection lamination portion is set to be equal to or more than 1.3 GPa.Type: GrantFiled: November 19, 2008Date of Patent: January 4, 2011Assignee: SRI Sports LimitedInventors: Masaru Kouno, Tomio Kumamoto
