摘要： This disclosure relates to dampeners for sporting equipment wherein the dampeners dampen or attenuate energy, such as vibrations or sound. The dampeners include polymeric compositions having butyl rubber polymers and, optionally, resins based on phenol-formaldehyde. The dampeners can be used in sporting equipment that requires attenuation and absorption of impact, vibration, and/or sound, and the dampeners may provide cushioning to the user.

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.

摘要： A composite material body (10) includes a first material layer (20) and a second material layer (30) overlapping the first material layer (20). The first material layer (20) and the second material layer (30) are wound to form a flexible and circular rod. Impact absorption is effectively improved and impact resisting strength is enhanced because energy-absorber or damping material or its composition is attached into the composite material body (10). Technical characteristics, effects and objects of this invention are achieved thereby.

摘要： A racquet including a frame including a head portion, a handle portion, and a throat portion. The head portion is a tubular structure including inner and outer peripheral walls, each having inner and outer surfaces. The head portion of the racquet being formed of a fiber composite material. The fiber composite material includes a plurality of ply arrangements. Each includes a pair of plies defining first and second angles with respect to a composite axis. A section of the outer peripheral wall from the inner surface to the outer surface includes at least three ply arrangements overlaying each other, and the first and second angles of at least two of the at least three ply arrangements being at least 35 degrees. When the racquet is tested under a racquet torsional stability test, the racquet has an angular deflection of less than 5.5 degrees about a longitudinal axis.

摘要： A racket frame has an inner thick part (28) having an outer surface (12), an inner surface (14) and a pair of middle surfaces (16) each positioned between the outer surface (12) and the inner surface (14). A thickness (Ti) of the inner surface (14) is greater than a thickness (To) of the outer surface (12). A thickness of the inner thick part (28) gradually increases toward the inside. Consequently, the middle surface (16) is inclined with respect to an X direction. A distance (Ld) between an outer end and an inner end in a thickness direction of the middle surface (16) is equal to or greater than 0.5 mm.

摘要： A sports product may include a support member and an impact region configured to impact an object. The impact region may be coupled to the support member. The sports product may also include a shear thickening material in at least one of the support member or the impact region. The shear thickening material may be configured to exhibit shear thickening behavior when an impact occurs between the impact region and the object.

摘要： A racquet includes polyester, monofilament racquet string and a frame extending along a longitudinal axis and including a head portion coupled to a handle portion. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having maximum longitudinal and transverse dimensions, a, and, b, respectively. The dimension a is at least 1.2 times the dimension b. The inner peripheral wall includes string holes. The string has a diameter within the range of 1.10 to 1.55 millimeters. The string forms a string bed of interlaced main and cross string segments. Each of the cross segments transversely extends from one of the string holes to another, and each of the main segments longitudinally extends from one of the string holes to another. The string bed has at least one more main segment than cross segment. At least one of the main segments contacting the tennis ball exhibits a snap back velocity of at least 1 meter per second.
