摘要： A racket frame formed of a frame core and FRP sheets adhered to ball-striking faces of the frame core. The present racket frame is so constructed such that each of the FRP sheets is made by slicing a laminated body consisting of a plurality of FRP plate elements and protective plates which laminated body is molded into the same configuration as that of the ball-striking faces of the frame core, each of the FRP plate elements is formed by long, continuous reinforcing rovings extending from one end to the other end of the plate element and being uniformly impregnated into the thermosetting resin under uniform tension, and said protective plates are arranged at the innermost and outermost sides of the molded laminated body.

摘要： A game racket frame such as a tennis racket frame having controlled stiffness properties and light weight making it possible to selectively add weight to the racket at the region in which such weight will do the most good, namely, along the transverse axis of the stringing area. The racket frame itself comprises an integral structure including a head portion, a throat portion and a handle portion, the structure being composed of high modulus fibers such as graphite, glass, boron or the like, in a matrix of a synthetic resin. The frame has a non-uniform cross-sectional configuration and a taper whereby the thickness of the handle portion is greater than the thickness in the head portion, and the thickness of the throat is intermediate that of the handle portion and the head portion. The frame is such as to provide a tapered beam with the greatest area moment of inertia where the bending moments are highest. A tennis racket utilizing the improved frame has an improved coefficient of restitution at high velocity impact, improved ball rebound characteristics for off-center hits and relatively low vibration transmissibility.

摘要： A novel structural member, such as a tennis racket frame, having an unusually high strength to weight ratio is provided comprising an expanded foamed plastic core integrally bonded to a shell comprising at least one layer of resin-coated unidirectionally oriented graphite fibers, the shell completely encasing the core at any transverse cross section of the structural member with a veiling strip wrapped around said core beneath the innermost or beyond the outermost of the graphite fiber layers, or both.The structural member is prepared by wrapping a veiling strip around a core strip comprising a foamable resin composition at least once around, wrapping at least one layer of resin-coated unidirectionally oriented graphite fibers about said veiling wrapped core with a starting edge of said graphite fiber layer below the outermost edge of said veiling strip, wrapping a second veiling strip about the outermost of said graphite layers with a starting edge of said last-named strip below the outermost edge of said last-named graphite layer, placing said wrapped core strip within a mold cavity, sealing the mold cavity and activating the foamable resin composition to cause expansion and generate pressure within the mold cavity and thereby provide intimate bonding of the core to the shell.

摘要： A racquet extending along a longitudinal axis and including a frame including a head portion, a handle portion, and a throat portion. The head portion forms a hoop that defines a string bed plane. At least the head portion and the throat portion of the frame are formed at least in part of a fiber composite material. When the racquet is tested under the racquet lateral bending test, the racquet has a lateral deflection of at least 6.0 mm when measured in a direction that is parallel to the string bed plane and perpendicular to the longitudinal axis. When the racquet is tested under the racquet torsional stability test, the racquet has an angular deflection of less than 5.5 degrees about the longitudinal axis. The head portion has a maximum beam height distance of at least 20 mm.
