As an alternative to metal materials, it is impregnated with resin-type angles and one-inch or several products. The habitual material is not king. It is necessary to set the large mechanical properties of the material to be long or dry, and the length of different weaving square inches is commonly referred to as short material for processing. In the piston part, various types of fiber and staple fiber can also be made into a combination. In addition to resin fiber aggregate composites In addition to the ratio of weight to weight, another important characteristic is that the fiber arrangement can obtain a suitable load distribution, and even if it is optimized, it is possible to design. Regarding the former staple fiber material instead of the traditional material, it is an example. You must use a long-fiber material to achieve °. Please refer to Figure 8 for further details. The composite material filling part (1 2 3) between the piston fitting part and the center interface ring fitting part is located near the inner side of the piston fitting part. The short fiber material is respectively filled in between the raised part and the protrusion on the outside of the central interface ring's fitting part, which are respectively represented by the part numbers (1231) and (1 233). Then insert the long fiber prefiber between the two short fibers.
