In our initial Platform Grant (GR/T18578/01) - we have been extremely successful in implementing a predictive modelling strategy at the fibre and textile (reinforcement) scale. This has been complemented by an extensive experimental programme, notably in manufacture of novel fibres and degradable composites and in development and optimisation of automated carbon fibre preforming technologies. Models at fibre scale have developed understanding of degradation for medical implants, mechanics of dry and impregnated tows, and influence of thermal and chemical shrinkage on residual stresses in thermoset composites. RVE models have enabled engineering science models for textile mechanics, fluid permeability, and elastic and failure behaviour for textile composites.Given the above, we propose to implement a multi-scale modelling approach for polymer composites, encompassing models at fibre tow, unit cell (RVE), laminate and component scales. The same philosophy that we have used successfully at the RVE scale, encompassed in the TexGen schema, will be applied - encompassing the critical engineering science within a user-friendly and flexible software environment, made publicly available where commercial considerations allow. For example one crucial area where this will be applied is in yarn/tow modelling, where we need to develop a schema representing fibre arrangements, incorporating statistical information for fibre paths. This will be an essential building block in the modelling strategy, and will be the focus of one of the Research Fellows.The strategy will be underpinned by an extensive experimental programme, validating the models and developing new processing technologies for our target application areas. We do NOT aim primarily to model standard materials or processes with high technology readiness levels; rather we aim to utilise our unique modelling capabilities and understanding to develop exciting new directions. This approach will be applied across our research portfolio, concentrating on:- automated manufacturing and processing- mechanical and physical performance- medical materials- technical textiles

在我们最初的平台资助 (GR/T18578/01) 中，我们非常成功地在纤维和纺织品（增强）规模上实施了预测建模策略。广泛的实验计划对此进行了补充，特别是在新型纤维和可降解复合材料的制造以及自动化碳纤维预成型技术的开发和优化方面。纤维尺度的模型已经深入了解了医疗植入物的降解、干丝束和浸渍丝束的力学，以及热收缩和化学收缩对热固性复合材料中残余应力的影响。 RVE 模型使纺织复合材料的纺织力学、流体渗透性以及弹性和失效行为的工程科学模型成为可能。鉴于上述情况，我们建议对聚合物复合材料实施多尺度建模方法，包括纤维丝束、晶胞（ RVE）、层压板和组件秤。我们将应用我们在 RVE 规模上成功使用的相同理念（包含在 TexGen 模式中）——将关键工程科学包含在用户友好且灵活的软件环境中，并在商业考虑允许的情况下公开提供。例如，应用这一技术的一个关键领域是纱线/丝束建模，我们需要开发一种表示纤维排列的模式，并结合纤维路径的统计信息。这将是建模策略中的一个重要组成部分，并将成为一位研究员的重点。该策略将以广泛的实验计划为基础，验证模型并为我们的目标应用领域开发新的处理技术。我们的主要目标并不是对具有高技术就绪水平的标准材料或流程进行建模；相反，我们的目标是利用我们独特的建模能力和理解来开发令人兴奋的新方向。这种方法将应用于我们的研究组合，重点关注： - 自动化制造和加工 - 机械和物理性能 - 医疗材料 - 技术纺织品
