美国的铁路车辆正在迅速地老化，其平均使用年头已达23年，而其预期寿命只有25年。铁路运输的主要用户要求使用更好的车辆来代管其日益老化的车辆，于是铁路车辆制造商寻求与复合材料制造商合作来研制新型复合材料车辆。木文阐述了如何利用复合材料未满足铁路运输部门的需要的。
American railways are aging rapidly, with an average life span of 23 years and a life expectancy of only 25 years. Major users of rail transport demand better vehicles to host their aging vehicles. Railway car manufacturers are therefore seeking to work with composite manufacturers to develop new composite vehicles. Mu Wen explained how to use the composite material does not meet the needs of the railway transport sector.
