By 2020, the advanced composite market is predicted to be worth around £17 billion, with automotive the second largest growth sector (after wind energy) but still falling far short of its enormous growth potential; the high cost of production for advanced composite products is still a major obstacle to their wider exploitation. Government legislation on the reduction of emissions is an important driver across the transport sector and one way to achieve prescribed targets is through the substitution of relatively heavy metallic components with highly optimised light-weight advanced polymer composite parts. Consequently, there is an urgent need to address the economic viability of manufacturing with advanced polymer composites and realise their full weight and fuel saving potential. The proposed project aims to contribute to this overarching goal by introducing an ambitious low-cost route to manufacturing highly optimised advanced composite structures. The ability to produce 'steered-fibre laminates' containing non-linear fibre paths, creates a step change in the design space for advanced composite structures. The designer is able to reposition stress concentrations away from holes and inserts, improve a laminate's resistance to buckling and failure, and to enhance a laminate's dynamic response to vibrations. Ultimately this can lead to lighter, more optimised structures for use in the aerospace and automotive sectors, enhancing fuel efficiency and contributing to the broader goals of reduced cost and lower emissions across the transport sector. The aim of the proposed project is to implement and demonstrate a novel and disruptive manufacture process that can produce low-cost high-quality steered-fibre laminates, without use of expensive, capital intensive automated fibre placement machines (the current solution). The new process is best described as 2-D forming; in order to support this novel manufacture process, a custom-designed suite of computer aided design and manufacture software will be developed. Computational tools for digital manufacturing are essential if 2-D forming is to be successfully achieved without inducing severe wrinkling and buckling of the deforming biaxial sheet. Reducing cost will effectively bring fibre-steering technology to a broader range of applications, increasing its economic impact and bringing new manufacturing capabilities to a wider industrial base, with the UK leading the way in this important area of manufacturing.

到2020年，预计高级综合市场的价值约为170亿英镑，汽车是第二大增长行业（仅次于风能），但仍远远远远远远远远远远远远远远远远不如其巨大的增长潜力。高级复合产品的高生产成本仍然是其更广泛利用的主要障碍。政府关于减少排放的立法是整个运输部门的重要驱动力，实现规定目标的一种方法是用高度优化的轻量级高级聚合物复合零件代替相对较重的金属组件。因此，迫切需要解决与先进聚合物公司制造业的经济可行性，并实现其全部重量和节省潜力。拟议的项目旨在通过引入雄心勃勃的低成本途径来制造高度优化的高级复合结构，从而为这一总体目标做出贡献。产生包含非线性纤维路径的“转向纤维层压板”的能力，在高级复合结构的设计空间中创造了步骤变化。设计师能够将应力浓度重新放置在孔和插入物中，提高层压板对屈曲和失败的抵抗力，并增强层压板对振动的动态反应。最终，这可能会导致在航空航天和汽车领域使用更轻松，更优化的结构，提高燃油效率，并为整个运输部门的成本降低和降低排放量的更广泛的目标做出了贡献。拟议项目的目的是实施和展示一种新颖的破坏性制造过程，该工艺可以产生低成本高质量的蒸汽纤维层压板，而无需使用昂贵的，资本密集的自动化纤维放置机器（当前的解决方案）。新过程最好被描述为二维形成。为了支持这个新颖的制造过程，将开发一个定制设计的计算机辅助设计和制造软件套件。如果要成功实现二维形成，那么对于数字制造的计算工具就至关重要，而没有引起变形双轴板的严重绕组和屈曲。降低成本将有效地将纤维探测技术带入更广泛的应用，增强其经济影响并将新的制造能力带入广泛的工业基础，英国在这一重要的制造业领域中领先。
