以电子计算机和空间技术的发展为标志的现代科学技术正在经历着空前的变革;而信息能源和材料已经成为实现这些变革的三大支柱.因为材料是一切科学技术发展的物质基础,因此其重要性是显而易见的.众所周知,复合材料是发展航天技术急需的新型材料.曾有人预测,本世纪末复合材料将成为宇航工业的主要结构材料,并将代替飞机上大部分金属材料.因此,国外有人称二十一世纪是“复合材料世纪”,是有一定道理的.美国把复合材料称为第四代防热材料,优先考虑用作下一代导弹的防热材料;日本把复合材料列为当代重点攻关的尖端材料.高级复合材料的生产与应用已经成为衡量一个国家科学技术发展水平的重要标志.
Modern science and technology, marked by advances in computer science and space technology, are experiencing unprecedented changes, and information energy and materials have become the three pillars of these changes, because material is the material basis for all scientific and technological developments and therefore important It is well known that composites are a much needed new material for the development of aerospace technology.It has been predicted that by the end of this century, composites will become the main structural material for the aerospace industry and will replace most of the metal materials on the aircraft. The 21st century is the “composite century,” which makes sense. The United States calls composite materials the fourth generation of heat-protection materials, giving priority to the use of heat-resistant materials for the next generation of missiles. Japan has made composite materials a contemporary priority Cutting-edge materials .High composite material production and application has become a measure of a country’s level of development of science and technology an important symbol.
