求翻译：碳纤维材料的重量约是一般钢板的四分之一，而强度却能达到钢板的10倍，今年10月开始商业运行的波音787机体采用碳纤维复合材料，可节省约2成燃油费。通常的碳纤维复合材料采用热硬化性树脂，生成复合材料需要10分钟，因所需时间较长无法实现量产，只能应用于价格高于1000万日元的雷克萨斯等高级车。是什么意思？

The weight of carbon fiber material is generally about a quarter of steel, and steel strength was able to achieve 10 times, began commercial operation in October this year, the Boeing 787 airframe made of carbon fiber composite materials, can save about 2 percent of fuel costs. Carbon fiber composit

Carbon fiber is the weight of about 4 General steel plate, and the intensity of steel plate can be reached in October of this year, 10 times since the Boeing 787 commercial running machine adopts carbon fiber composite material, can save approximately 2% fuel costs.
