The project aims to develop novel drawn polymer fibres with aligned carbon nanotubes incorporated inside and also grafted nanotubes on their surface. Such polymer fibres can be used to reinforce thermoplastics to make high performance composites with effective recyclability. This is important as the existing thermosetting composites are not recyclable and significant property enhancement require high loading (>30%) of reinforcing fibres. The outcomes of this project will be novel technology for making high stiffness polymer fibres and their use in thermoplastic composites. The benefits will be to allow easy processing and recycling. They will be used in down-sizing of high volume products and high value automotive or aerospace products.

该项目旨在开发新型拉伸聚合物纤维，其内部含有对齐的碳纳米管，表面也接枝了纳米管。这种聚合物纤维可用于增强热塑性塑料，以制造具有有效可回收性的高性能复合材料。这是重要的，因为现有的热固性复合材料是不可回收的，并且显著的性能增强需要高负载（>30%）的增强纤维。该项目的成果将是制造高刚度聚合物纤维及其在热塑性复合材料中的应用的新技术。其好处是便于加工和回收。它们将用于大批量产品和高价值汽车或航空航天产品的小型化。
