项目摘要

The UK composites sector has the potential to grow from £2.3Bn to £12Bn by 2030, driven by demand for light weight, energy efficient structures across sectors including aerospace, automotive, marine and renewable energy. In addition to economic considerations, the growth of composites manufacturing is also key to meeting the Government's Net Zero targets through, for instance, increased deployment of UK manufactured wind turbines.The UK has world leading research capability in composites manufacturing focussed on design, process innovation, novel and sustainable material combinations and modelling tools. Instrumentation to support this research community, by monitoring composites manufacturing processes, has fallen behind and this will potentially hinder the realisation of the full value of current research activities. Researchers and manufacturers need better data about the complex mechano-thermo-chemical processes which occur during resin infusion and curing in order to improve yield, reduce waste and speed the introduction of new component designs and material combinations. We have demonstrated that fibre optic sensors, are able to monitor individual key process parameters of resin flow front position and velocity and degree of curing, as well as temperature and strain, in real time at many measurement points. However, to make a useable instrument, where multiple measurands are extracted, it is necessary to use heterogeneous combinations of co-located sensors with appropriate signal processing to disaggregate the desired information. We will adopt combinations of Fibre Bragg Grating sensors to monitor temperature and strain with Long Period Gratings to monitor resin motion and refractive index and hence degree of curing. In order to address the cross sensitivity of these sensors, we will adopt sophisticated signal processing techniques to disaggregate measurements and extract the desired measurands in a form appropriate to users. In addition, sensors need to be encapsulated and connected in a manner which makes them easy to handle and deploy. We will develop packaging solutions and mesh configurations which provide robustness. We will seek to develop this technology into a cost effective instrument which can be used by scientists and engineers, who are not photonics experts, but who seek to gain better understanding of the complex but critical processes which occur during composite manufacture.

英国复合材料行业有可能从2030年的23亿英镑增长到12030英镑，这是对轻量重量的需求，包括航空航天，汽车，海洋和可再生能源在内的各个部门的节能结构的驱动。除了经济考虑之外，复合材料制造业的增长也是实现政府净零目标，例如，通过增加英国制造的风力涡轮机的部署。英国在专注于设计，过程创新，新颖和可持续的材料组合和建模工具的公司中具有世界领先的研究能力。通过监视组成制造过程来支持该研究社区的仪器已落后，这可能会阻碍现实的现实当前研究活动的全部价值。研究人员和制造商需要更好的数据，以了解在树脂输注和固化过程中发生的复杂机械 - 热化学过程，以提高产量，减少浪费并加快新成分设计和材料组合的引入。我们已经证明，光纤传感器能够在许多测量点上实时监视树脂流前位置，速度以及温度和应变程度的单个关键过程参数。但是，要制作一个可用的仪器，在提取多个测量值的情况下，有必要使用与合适的信号处理的共同定位传感器的异质组合来分解所需的信息。我们将采用纤维布拉格光栅传感器的组合，以长时间的光栅监测温度和应变，以监测树脂运动和折射率，从而监测固化程度。为了解决这些传感器的交叉灵敏度，我们将采用复杂的信号处理技术来分解测量，并以适合用户的形式提取所需的测量。此外，需要以使其易于处理和部署的方式封装和连接传感器。我们将开发包装解决方案和网状配置，以提供鲁棒性。我们将寻求将这项技术开发为一种具有成本效益的工具，该工具可以由科学家和工程师使用，他们不是光子学专家，但他们试图更好地了解复合制造过程中发生的复杂但关键过程。
