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

在我们最初的平台赠款（GR/T18578/01）中 ​​- 我们在纤维和纺织（增强）量表上实施预测建模策略方面非常成功。这是一项广泛的实验计划的补充，尤其是在新型纤维和可降解的复合材料以及自动化碳纤维预制技术的开发和优化方面进行了补充。纤维尺度上的模型已经对医疗植入物的降解，干燥和浸渍的tows机制以及热和化学收缩对热固性复合材料中残留应力的影响有所了解。 RVE模型使工程科学模型用于纺织力学，流体渗透性以及纺织复合材料的弹性和故障行为。上面，我们建议对聚合物复合材料实施多尺度的建模方法，并在光纤牵引，单位细胞（RVE），层压板和组件尺度上包含模型。我们在Texgen模式中成功使用的rve量表中成功使用的理念将被应用 - 涵盖在用户友好且灵活的软件环境中的关键工程科学，并在商业考虑允许的情况下公开可用。例如，将在纱线/拖曳建模中使用它的一个关键区域，我们需要在其中开发代表纤维布置的模式，并结合纤维路径的统计信息。这将是建模策略中重要的基础，并且将是其中一项研究人员的重点。该策略将由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。我们不主要是为具有高科技准备水平的标准材料或过程建模；相反，我们旨在利用我们独特的建模功能和理解来开发令人兴奋的新方向。这种方法将在我们的研究组合中采用： - 自动制造和处理 - 机械和物理性能 - 医疗材料 - 技术纺织品
