If demand for production of next-generation, short-range commercial aircraft is to be profitably met, current methods for composite airframe manufacture must achieve significant increases in material deposition rates at reduced cost. However, improved rates cannot come at the expense of safety or increased airframe mass. This project will enable a fourfold increase in productivity by establishing novel manufacturing techniques that speed up deposition of stiffness tailored material. New continuum mechanics-based forming models will ensure delivery of better products by minimising occurrence of manufacturing defects. In a parallel stream of activity, new methodologies for analysis and design of composite structures in which the ply angle and thickness of fibre-reinforcement is spatially tailored, both continuously and discretely, will reduce the need for stiffening, leading to significant savings in structural mass (by up to 30%) and manufacturing cost (by up to 20%). Potential structural integrity and damage tolerance issues, such as transition in fibre angle and tapering of laminate thickness from one discrete angle to another, will be addressed. The project will engage a multidisciplinary team of engineers and applied mathematicians to develop novel manufacturing and modelling techniques. An embedded university-industry partnership will focus on the creation of new manufacturing and analysis capabilities, supported by fundamental research. Academics at Bath and Exeter will partner with the National Composites Centre and with industrial collaborators that span the airframe supply chain. The project will enable production of high performance composite components at rates suitable for the next generation of short-range aircraft. There are also opportunities for impact in the wider composites manufacturing industry, including automotive and energy sectors.

如果要以有利可图的方式满足下一代短程商用飞机的生产需求，目前的复合材料机身制造方法必须以更低的成本大幅提高材料沉积速度。然而，速度的提高不能以牺牲安全或增加机身质量为代价。该项目将通过建立新的制造技术来加快硬度定制材料的沉积，从而使生产率提高四倍。新的基于连续介质力学的成形模型将通过最大限度地减少制造缺陷的发生来确保交付更好的产品。与此同时，分析和设计复合材料结构的新方法，其中纤维增强材料的铺层角度和厚度可以连续和离散地在空间上定制，将减少对加强的需求，从而显著节省结构质量(高达30%)和制造成本(高达20%)。将解决潜在的结构完整性和损伤容限问题，如纤维角度的过渡和层压板厚度从一个离散角度向另一个离散角度的渐变。该项目将聘请一个由工程师和应用数学家组成的多学科团队来开发新的制造和建模技术。在基础研究的支持下，嵌入的大学和行业伙伴关系将专注于创造新的制造和分析能力。巴斯和埃克塞特的学者将与国家复合材料中心和跨越机身供应链的工业合作者合作。该项目将能够以适合下一代短程飞机的速度生产高性能复合材料部件。在更广泛的复合材料制造业，包括汽车和能源行业，也有影响的机会。
