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.

到 2030 年，由于航空航天、汽车、船舶和可再生能源等行业对轻质、节能结构的需求，英国复合材料行业有潜力从 23 亿英镑增长到 120 亿英镑。复合材料制造也是实现政府净零目标的关键，例如通过增加英国制造的风力涡轮机的部署。英国在复合材料制造方面拥有世界领先的研究能力，专注于设计、工艺创新、新颖和可持续材料通过监测复合材料制造过程来支持该研究界的仪器已经落后，这可能会阻碍当前研究活动的全部价值的实现。树脂灌注和固化过程中发生的化学过程，以提高产量、减少浪费并加快新组件设计和材料组合的引入。我们已经证明，光纤传感器能够监测树脂流动前沿位置的各个关键过程参数。以及速度和程度然而，为了制造一个可提取多个被测量的可用仪器，有必要使用同位传感器的异构组合以及适当的信号处理来分解这些测量值。我们将采用光纤布拉格光栅传感器的组合来监测温度和应变，并使用长周期光栅来监测树脂的运动和折射率，从而监测固化程度。为了解决这些传感器的交叉敏感性问题。采用复杂的信号处理技术来分解测量结果并以适合用户的形式提取所需的被测量。此外，传感器需要以易于处理和部署的方式进行封装和连接。我们将寻求将该技术开发成一种具有成本效益的仪器，可供科学家和工程师使用，他们不是光子学专家，但寻求更好地了解复合材料制造过程中发生的复杂但关键的过程。
