TEFSC will develop key enablers for the industrial adoption of the Rapid-Tow-Shearing (RTS), a novel composites manufacturing technology, which allows the placement of wide carbon tapes along curved paths (fibre-steering) without the defects (gaps/overlaps/wrinkles) typically seen with existing Automated Fibre Placement / Tape Laying technologies (AFP/ATL). Fibre steering drastically increases the structural performance of composite structures. Being able to continuously tailor orientations and place fibres along load-paths can contribute significantly towards the optimised use of composite materials, leading to lightweight cost-effective sustainable composite components across crucial composite sectors such as aerospace, space, automotive and wind energy.Current design methods make use of a series of well-established mechanical characterisation tests (ASTM standards) to obtain material allowables data. These test methods are suitable for coupons manufactured using straight fibres. However, the unique properties and behaviours arising from curved fibre designs mean that new test methods must be developed to provide a thorough understanding of these behaviours as steered composites can lead to effects in the secondary direction. The lack of an established testing method for fibre-steered components hinders wide adoption of the RTS process due to barriers related to certification, especially for highly regulated aerospace and space applications.TEFSC-II builds upon TEFSC (IUK-10039205). In TEFSC, a series of fibre-steered coupons at different steering-angles were tested setting the basis for mechanical characterisation of fibre-steered components. TEFSC-II aims to further investigate this focusing on the effect of fibre-waviness and volume-fraction variations on fibre-steered parts. This will de-risk and provide a route to certification of this novel process, to enable it to be taken forward in the future as a viable means for manufacturing the next generation of composite components.The TEFSC-II project will begin in January 2024 and runs for 6 months, by which point thorough understanding of the mechanical behaviour of fibre-steered components will be established. Successful completion of TEFSC-II will pave the way for certification accelerating adoption of RTS in highly regulated applications such as aerospace and space.

TEFSC将为快速牵引剪切（RTS）的工业应用开发关键推动因素，RTS是一种新型复合材料制造技术，允许沿沿着弯曲路径放置宽碳带（纤维转向），而不会出现现有自动纤维放置/铺带技术（AFP/ATL）通常会出现的缺陷（间隙/重叠/褶皱）。纤维转向显著提高了复合材料结构的结构性能。能够不断调整方向并沿着载荷路径放置纤维可以为复合材料的优化使用做出显着贡献，从而在航空航天、航天、汽车和风能等关键复合材料领域提供轻质、经济、可持续的复合材料部件。当前的设计方法利用一系列成熟的机械特性测试（ASTM标准）来获得材料允许数据。这些试验方法适用于使用直纤维制造的试样。然而，弯曲纤维设计所产生的独特性能和行为意味着必须开发新的测试方法，以提供对这些行为的透彻理解，因为转向复合材料可能导致次级方向的影响。由于认证方面的障碍，特别是在高度管制的航空航天应用中，光纤操纵组件缺乏既定的测试方法，阻碍了RTS过程的广泛采用。TEFSC-II建立在TEFSC（IUK-10039205）的基础上。在TEFSC中，对一系列不同转向角的纤维转向试样进行了测试，为纤维转向部件的机械特性奠定了基础。TEFSC-II旨在进一步研究这一点，重点是纤维波度和体积分数变化对纤维转向部件的影响。TEFSC-II项目将于2024年1月开始，为期6个月，届时将建立对纤维操纵部件机械性能的全面了解。TEFSC-II的成功完成将为认证铺平道路，加速RTS在航空航天等高度监管的应用中的采用。
