Abstract: A shock absorbing structure of a racket contains: a head and an absorption member matingly contacting with an internal fence of the head. The absorption member is a hollowly tubular structure and covers the internal fence totally. When the head is made of carbon-fiber composite material, the absorption member is made of any one of Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU). When the head is made of metal or aluminum alloy, the absorption member is made of any one of Thermosetting Elastomers, Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU). When the head and the absorption member are made of different materials, an amplitude of the head is different from an amplitude of the absorption member, and the head interferes the absorption member, thus absorbing vibration.

Abstract: Fine-grained (average grain size 1 nm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.

Abstract translation: 公开了细粒度（平均粒径1nm至1000nm）金属涂层，其任选地含有分散在其中的固体颗粒。 由于Hall-Petch强化，细粒金属材料比同一化学成分的常规涂层显着更硬和更强，并且具有低线性热膨胀系数（CTE）。 本发明提供了通过调节合金的组成和/或通过改变嵌入涂层中的微粒的化学和体积分数来匹配细粒金属涂层的CTE与基体之一的方法。 细粒金属涂层特别适用于强而轻的制品，精密模具，运动用品，汽车零件和暴露于热循环的部件。 低CTE和将细粒金属涂层的CTE与衬底的CTE匹配的能力使热循环期间的尺寸变化最小化并防止过早失效。

Abstract: A metal baseball or softball bat may be improved both for durability and performance by selectively placing a layer of fiber reinforced composite material around portions of the bat. In one embodiment, the barrel portion of the bat may have a fiber reinforced composite layer directly laid up upon the metal bat frame. In a second embodiment, the barrel portion of the bat may include an outer metal sleeve placed about the metal bat frame, with an exterior fiber reinforced composite shell being formed on the outer metal sleeve. In a third embodiment, an intermediate portion of the bat adjacent a zone of maximum bending stress may be reinforced by the placement of a fiber reinforced composite outer layer on the metal frame of the bat adjacent the area of maximum bending stress.
