  报告摘要:
  Modern composites, made up of carbon fibres and toughened epoxy resins, are lighter/stiffer/stronger and increase fuel efficiency in aircraft, compared with the aluminium currently used. They have been used in the Airbus A380 super jumbo, the first fully double-decked passenger jet (with more than 550 seats, but certified for 853 passengers), the Boeing 787 ‘Dreamliner’ aircraft and the A350 that came to service in 2015. The primary structure, including the wing and fuselage, of the B787 200-seater passenger jet is built mostly from composite materials and is advertised to be 20% more fuel efficient than current commercial planes with almost 60% more cargo space than the Airbus A300-200. It is accepted that modern composite systems offer a variety of advantages, however, affordability (reduced acquisition and direct operating costs, while maintaining or enhancing safety) is the key to survival in aerospace manufacturing, whether civil or military. Therefore current research effort is devoted to analysis and computational simulation of the manufacturing and assembly process as well as the simulation of the performance of the structure, since these are intimately connected.
In this talk, applications of modern composite systems will be presented and achievements, but also challenges, in the modelling and characterization of such materials will be discussed with some thoughts on future needs, developments and prospects for novel materials (3D woven architectures) and processes, structural health monitoring (SHM), maintenance and repair. Textile technologies such as weaving, braiding, stitching, tufting and embroidery, which are at the heart of preforming research at Manchester, will be presented since they can lead to more damage resistant and tolerant designs of interest to aerospace, automotive and marine industries. Some novel fibre placement machines that have been developed by combining expertise in textile technology and robotics will also be shown.
