Effective dispersion of carbon nanotubes (CNTs) in the polymer matrix of fibre-reinforced composites is challenging due to the re-agglomeration and filtration of CNTs that occur during the processing of composite materials. In this study, resin film infusion (RFI) process is used for manufacturing composite laminates and investigating the degradation of CNT dispersion during high-temperature processing of a thermoset fibre-reinforced composite. Dispersion stability is investigated by studying the re-agglomeration of CNTs in the resin caused by variations in resin physiochemical properties. Filtration of CNTs by fibre tows is studied by investigating two layup strategies. The effect of CNT dispersion on the mechanical and electrical properties of composites is evaluated by performing compression-after-impact experiments and electrical conductivity measurements.

由于在复合材料的加工过程中发生的CNT的重新团聚和过滤，碳纳米管（CNT）在纤维增强复合材料的聚合物基质中的有效分散具有挑战性。在这项研究中，树脂膜灌注（RFI）工艺用于制造复合材料层压板，并研究在热固性纤维增强复合材料的高温加工过程中CNT分散体的降解。通过研究由于树脂理化性质变化而引起的CNT在树脂中的再聚结，研究了分散体的稳定性。通过研究两种铺层策略，研究了用纤维束过滤碳纳米管的方法。
