众所周知,我们的能源主要消耗在工业过程和日常生活中。比如,与人们生涯息息相关的汽车几乎消耗了世界上1/3的石油,制造了近1/4的二氧化碳排放。此外,航空、轨道交通等领域也不例外。因此,“节能减排”已成为制造业实现可持续发展的关键词。有研究表明,交通工具的能耗与它的重量直接相关,比如,轿车每减轻10%,燃油消耗就减少6%到8%。可以说,“轻量化”应该是节能减排的最有效手段之一,而“轻量化”最直接、最有效的手段是在保证性能不变的情况下采用密度更轻的新材料替代传统制造材料,比如,美国波音最新的787飞机大部分就
As we all know, our energy is mainly consumed in industrial processes and daily life. For example, cars that are closely linked to people’s lives consume almost one-third of the world’s oil and produce nearly a quarter of their carbon dioxide emissions. In addition, aviation, rail transit and other fields are no exception. Therefore, “energy-saving emission reduction” has become the key word for manufacturing to achieve sustainable development. Studies have shown that the energy consumption of vehicles is directly related to their weight. For example, every 10% reduction in sedan consumption reduces fuel consumption by 6% to 8%. Can be said that “Lightweight ” should be one of the most effective means of energy-saving emission reduction, and “Lightweight ” The most direct and most effective means is to ensure that the same performance without changing the density of the new Materials to replace traditional manufacturing materials, for example, most of the Boeing 787 aircraft on the United States
