    • A ball bat exhibits improved barrel performance in regions located away from the “sweet spot” of the bat barrel, as a result of strategic placement of interface shear control zones (“ISCZs”) in the barrel. The ball bat includes a barrel having a first region adjacent to the tapered section of the ball bat, a second region adjacent to the free end of the barrel, and a third region located between the first and second regions, that includes the sweet spot of the barrel. The first and second regions each include at least one interface shear control zone. The third region includes at least one fewer interface shear control zone than at least one of the first and second regions. ISCZs may also be strategically placed in the bat handle and/or the tapered section of the ball bat to improve the compliance and overall performance of the ball bat.
    • 由于在桶中界面剪切控制区(“ISCZ”)的战略布置,球蝙蝠在远离“棒棒”的“甜点”的地区表现出改善的桶表现。 球槌包括具有与球蝙蝠的锥形部分相邻的第一区域的第二区域,与桶的自由端相邻的第二区域,以及位于第一和第二区域之间的第三区域, 桶。 第一和第二区域各自包括至少一个界面剪切控制区。 第三区域包括比第一和第二区域中的至少一个少至少一个界面剪切控制区域。 ISCZ还可以战略性地放置在蝙蝠手柄和/或球蝙蝠的锥形部分中,以提高球蝙蝠的顺从性和整体性能。

    • A ball bat includes a barrel having a substantially cylindrical outer wall including a first material located radially outwardly from a neutral axis of the outer wall, and a second material located radially inwardly from the neutral axis of the outer wall. The barrel further includes a substantially cylindrical inner wall located within the outer wall and including a third material located radially outwardly from a neutral axis of the inner wall, and a fourth material located radially inwardly from the neutral axis of the inner wall. The first and third materials each have a specific energy storage in compression of at least 2000 psi, and the second and fourth materials each have a tensile modulus of at least 18 million psi. The ball bat exhibits excellent performance and durability characteristics.
    • 球棒包括具有基本上圆柱形的外壁的筒,该外壁包括从外壁的中性轴线径向向外定位的第一材料,以及从外壁的中性轴线径向向内定位的第二材料。 桶还包括位于外壁内的基本上圆柱形的内壁,并且包括从内壁的中性轴线径向向外定位的第三材料以及从内壁的中性轴线径向向内定位的第四材料。 第一和第三材料各自具有压缩至少2000psi的比能量储存器,并且第二和第四材料各自具有至少1800万psi的拉伸模量。 球棒表现出优异的性能和耐用性。
