由钢筋混凝土筑成的桥梁、隧道、仓库,在经过自然磨损之后其承重性会有所降低。为了提高上述建筑物的承重性,延长其使用寿命,全俄航空材料研究所开发出了新型碳塑修补材料。据俄《科学与生活》杂志报道,研究人员在“苏”系列战机机翼加 Bridges, tunnels, and warehouses made of reinforced concrete will have a reduced load bearing capacity after natural wear and tear. In order to improve the bearing capacity of these buildings and prolong their service life, the All-Russian Aeronautical Materials Research Institute has developed a new type of carbon-plastic repair material. According to the Russian “Science and Life” magazine reported that researchers in the “Su” series of fighter wings plus
