日本液压行业的一流企业萱场工业公司开发了一种能耐高压的碳纤维液压缸。这种液压缸重量轻,仅为常见的铸铁材料缸重量的三分之一并具有不带磁性的特点。缸的零件如管道、活塞杆等,可全部使用碳纤维材料,也可用碳纤维和部分铸铁两种材料的组合体。该公司早先是以实现飞机轻量化这一高要求为出发点而展开科研的,并计划五年后推出 Hita Industrial Co., a leading Japanese hydraulic company, has developed a high-pressure carbon fiber hydraulic cylinder. This cylinder is light weight, only one-third of the weight of a common cast iron cylinder and is non-magnetic. Cylinder parts such as pipes, piston rods, etc., all use of carbon fiber materials, carbon fiber can also be part of a combination of two materials and cast iron. Earlier, the company started research based on the high demand for lightweight aircraft and plans to launch it five years later
