摘要
Advanced composites are critical materials for the development of high-end equipment,as we say one generation of materials and one generation of equipment.Following materials such as aluminum,steel,and titanium,composite materials will become one of the four major materials in the field of aeronautics and astronautics.Usage of advanced composites is expected to exceed 50%in new commercial airplanes to significantly improve the level of lightweight.Thus,innovative devel-opment of high-end equipment in aerospace,rail traffic,biomedical and other fields also have an urgent demand for high-performance and multi-functional composites.
