INFINITE: Aerospace Composites digitally sensorised from manufacturing to end-of-life

INFINE的目标是开发基于铁磁性微丝的传感器和分析仪，将其嵌入航空航天复合材料结构部件中，以便在部件的整个生命周期中监控制造和结构健康。无线监测系统将允许产生数字信号和大量与样本链接的数据集，以创建该结构的建成数字孪生兄弟，该数字孪生结构还将说明自其通过执行的所有维护操作制造以来的整个历史，直到被最佳回收。无限公司打算通过开发功能性感应式非卷曲织物(NCF)来改进复合材料制造和结构健康监测(SHM)。这些织物将通过无线监测纤维位置、取向、应变应力和温度，通过自感知纤维提供高效的实时监测系统。这将通过施加安全的磁信号来实现，该信号在制造过程中(温度和纤维控制)以及部件的寿命期间提供体积信息。在运行中，新的SHM系统将提供有关部件完整性、性能和安全的信息，从而通知和改进维护操作。新的感应式NCF还将实现对复杂部件的新修复能力。微丝在织物中的集成为使用现有传感技术设计未来的功能复合材料开辟了新的可能性。这种先进的质量监控有可能对复合材料部件的成本和安全可靠性产生重大影响，为欧洲制造商和MRO提供竞争优势。INFINE还旨在评估传感硬件对当前复合材料回收方法的影响，调查重复使用(其他应用、行业等)的潜力。传感器和组件均可提供有用的报废功能。

INFINITE aims to develop sensors and analyser based on the usage of ferromagnetic microwires to be embedded in aerospace composite structural parts, in order to monitor manufacturing and structural health throughout the whole life cycle of the component. The wireless monitoring system will permit producing digital signals and vast sets of data linked with the specimen to create an as-built digital twin of the structure that will also account for the whole history since it was manufactured through all maintenance operations performed, until being optimally recycled. INFINITE intends to deliver improvements in composite manufacturing and structural health monitoring (SHM) by the development of functional sensorised Non-Crimp fabrics (NCF). These fabrics will provide an efficient real-time monitoring system through a self-sensing fibre by wireless monitoring of the fibre position, orientation, strain-stress and temperature. This will be achieved by applying a safe magnetic signal, providing a volumetric information during the manufacture process (temperature and fibre control) but also during the life of the component. In service, the new SHM system will provide information about component integrity, performance and safety; therefore informing and improving maintenance operations. The new sensorised NCF will also enable a new repair capability for complex parts. Integration of microwires in the fabric opens new possibilities in the design of future functional composites using existing sensoring technologies. This advanced quality monitoring has the potential to deliver a significant impact on cost and safety reliability of composite components, providing a competitive advantage of European manufactures and MROs. INFINITE also aims to assess the effect of sensoring hardware on the current methods for composite recycling, investigating the potential for re using (other applications, sectors, etc.) both sensors and components to provide useful end of life functionality.
