    • A ball bat extending about a axis, and including a barrel portion formed of a fiber composite material. The material includes first and second plies arrangements. The first and second ply arrangements define first and second ply arrangement thicknesses, respectively. The first and second arrangements include at least one ply having first and second plurality of fibers and first and second resin, respectively. The first and second arrangements define at least one first angle and second angle with respect to the axis, respectively. Each of the at least one first angle is of the same angular polarity and each of the at least second angle is of the same angular polarity. The first angle is of opposite polarity of the second angle. The ratio of the first and second arrangement thicknesses is at least 1.5. The first arrangement is positioned over and within 0.002 in of the second arrangement.
    • 围绕轴线延伸的球棒,包括由纤维复合材料形成的筒形部分。 该材料包括第一和第二层布置。 第一和第二层布置分别限定第一和第二层布置厚度。 第一和第二布置包括分别具有第一和第二多根纤维和第一和第二树脂的至少一层。 第一和第二装置分别限定相对于轴线的至少一个第一角度和第二角度。 所述至少一个第一角度中的每一个具有相同的角度极性,并且所述至少第二角度中的每一个具有相同的角度极性。 第一角度与第二角度具有相反的极性。 第一和第二布置厚度的比率至少为1.5。 第一布置位于第二布置中的上方且在0.002英寸内。
