摘要： A golf club (10) configured to be positioned in a golf ball address position. The golf club (10) includes a body (20) having a heel portion (32) and a toe portion (30), and a face (22) coupled to the body (20). A composite axis (60) extends from the heel portion (32) to the toe portion (30) and is parallel to ground when the golf club (10) is positioned in the golf ball address position. The face (22) has a golf ball contact surface (44) and a rear surface (46). The face (22) is formed of a fiber composite material including at least first and second sets of ply arrangements. Each of the ply arrangements include a pair of plies (50a, 50b) with one ply (50a) having a first plurality of fibers (56) defining a first angle with respect to the composite axis (60) and the other ply (50b) having a second plurality of fibers (56) defining a second angle with respect to the composite axis (60). The pair of plies (50a, 50b) include at least one resin (54). The first and second pluralities of fibers (56) of the first set of ply arrangements are glass fibers and the first and second pluralities of fibers (56) of the second set of ply arrangements are carbon fibers. The first set of ply arrangements is positioned closer to the golf ball contact surface (44) than to the rear surface (46), and the second set of ply arrangements is positioned closer to the rear surface (46) than to the golf ball contact surface (44). The ratio of the number of ply arrangements of the first set of ply arrangements to the number of ply arrangements of the second set of ply arrangements is at least 0.25.

摘要： A tennis ball including a non-foamed thermoplastic core defining an internal volume. The core includes a thermoplastic material having a specific gravity of 0.86 to 1.38, a flexural modulus of 2.0 to 50.0 MPa, and a Shore D hardness of 10 to 70. A thickness of the thermoplastic material is between 3.0 and 8.0 mm. The thickness of the thermoplastic material is configured to maintain dimensional stability at internal pressures of between 0 and 1.03 bar (0 and 15 psi).
