Analysis and Design for Accelerated Production and Tailoring of composites (ADAPT)

如果要盈利地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在降低成本的情况下实现材料沉积速率的显著提高。然而，提高速度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，加快硬度定制材料的沉积，使生产率提高四倍。新的基于连续力学的成形模型将通过最小化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（连续或离散地定制纤维增强的厚度和厚度）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%）。潜在的结构完整性和损伤容忍度问题，如纤维角度的转变和层压板厚度从一个离散角度到另一个逐渐变细，将得到解决。该项目将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。嵌入式大学-工业伙伴关系将侧重于在基础研究的支持下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以及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行业，包括汽车和能源行业，也有机会产生影响。

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.
