According to "see items such as safety toe cap, narrow H * +, skate base, golf head, etc., in: Tun Cup, ice hockey impact surface, and if you can increase the impact surface: It ’s all in use-the normal reinforcement structure is best not to occupy the volume, so that: f ,,, "", and the added shape changes, and does not affect the weight of the original item of the item or any item; The impact resistance is strong [and enhance the items :: Energy two ::: Increase effector. > Here we take the safety toe as an example to explain that the shoes worn by the brother seal and the use effect must have a safety toe, in order to: a worker in the knife industry arrives and is injured, but the average person in the market is damaged. The impact of the heavy object or the tablet frame is formed on the toe part. It is made of metal materials such as steel compressive strength and other mechanical properties. However, it will have excellent impact strength and inconvenience. The father is heavy, which is likely to cause the wearer to r .., Uiber has fiber reinforced resin (fibre reinforced Piastic) made of Uiber. The aforementioned metal material is too heavy, and the missing queen toe is released, which effectively improves the safety test. Surname ^ 9, but its mechanical strength is difficult to achieve: Wang test: the standard, especially in terms of endurance, resulting in its safety. The second aspect is even more ^ No 4 ', and this creation is designed to improve the above-mentioned design deficiency. M244200 Amendment This year 五 Supplement 5. The design description (2). [Content] The reason is that the main purpose of this creation is to provide a thin layer reinforcement structure for the impact-resistant surface of the article, and the reinforcement structure includes a base layer body and at least one reinforcement layer, wherein the base layer system is an outer frame of the article Shaped sheet body (such as the shape of a toe), made of fiber-reinforced thermosetting resin, and can be a single-layer or multi-layer structure; and the reinforcing layer is made of thermoplastic resin fiber cloth impregnated with thermosetting resin When the base layer body is a multi-layer structure including a plurality of layers of fibers, the reinforcing layer may be sandwiched between the plurality of layers of fibers At the same time, the reinforcing structure formed by the base body and the reinforcing layer makes the impact-resistant surface of the article have excellent mechanical strength, and is lightweight without increasing any weight of the original article, and can improve the use efficiency. [Implementation] In order to make this creation clearer and more detailed, and to provide a better understanding of the characteristics of this creation, the following diagrams are described in detail below: First, the "thin-layer reinforcement structure of the impact-resistant surface of the article" "Because it can improve the impact resistance and it is a thin layer structure that does not occupy volume, it can be applied to a variety of normal impacts such as safety toe caps, baseball bats, ice hockey bats, skate bases, golf heads, etc. On the surface, such as on the hitting surface of baseball bats, ice hockey bats or golf clubs, or on the base of skates that often jump and hit the ground or ice.
