A meso-scale finite element modelling strategy was developed to investigate the effect of hybridisation on the compaction response of multilayer stacks combining glass and carbon dry woven fabrics. It is expected that the electrochemical-mechanical properties of emerging multifunctional hybrid composites are strongly dictated by the morphology of the compacted reinforcements, yet no investigations into their compressibility have been reported. Model predictions were evaluated against compressibility measurements for monolithic and hybrid fabric stacks. The ply offset had a major influence on the predicted internal morphologies and fibre content, contributing to experimental variability thereof. Optical microscopy and micro X-ray computed tomography imaging further indicated greater likelihood of intermediate ply offsets in physical specimens, over limit case idealisations. Compressibility was slightly reduced in the hybrid multilayer stacks studied in this work. The model outputs presented are being used to analyse the electrochemical-mechanical response of monolithic and hybrid woven structural power composites.

研究了介观尺度的有限元建模策略，以研究杂交对结合玻璃和碳纤维干法织物的多层堆叠的压实响应的影响。可以预期，新兴的多功能杂化复合材料的电化学-机械性能在很大程度上取决于压实增强物的形态，但尚未报道对其可压缩性的研究。针对整体和混合织物叠层的可压缩性测量评估了模型预测。帘布层偏移量对预测的内部形态和纤维含量具有重大影响，有助于其实验可变性。光学显微镜和X射线计算机断层摄影成像进一步表明，物理样品中中间层偏移的可能性更大，超限情况下的理想化。在这项工作中研究的混合多层堆叠中，可压缩性略有降低。提出的模型输出已用于分析整体式和混合编织结构动力复合材料的电化学-机械响应。
