日本东燃公司开发出桥梁或混凝土烟囱等建筑物加固或修补用的碳纤维薄板。其重量仅为铁的1/5,而强度却为铁的6倍,所以总的成本比以往采用金属材料的工程要低。碳纤维在这种领域中的应用还是首次。希望能将应用范围扩展到车辆、船舶及工业用设备等方面。这种薄板是在涂环氧树脂的玻璃布上按一个方向加一层晴纶(PAN)系碳纤维而制成。使 Japan’s Dongdan Corporation has developed carbon fiber sheets for reinforcement or repair of buildings such as bridges or concrete chimneys. Its weight is only 1/5 of that of iron, and its strength is 6 times that of iron, so the total cost is lower than the previous projects using metal materials. The application of carbon fiber in this field is still the first time. We hope to expand the scope of application to vehicles, ships, and industrial equipment. This sheet is made by adding a layer of acrylic (PAN) carbon fiber in one direction on an epoxy-coated glass cloth. Make
