Abstract

Despite being a relatively mature manufacturing technology, in-situ automated fibre placement is still yet to see industrial implementation for the manufacturing of primary and secondary aircraft structures owing to fears of high porosity and inferior mechanical properties. In this study, carbon fibre-reinforced PPS is used as a reference material, with which several laminates are manufactured both in-situ and as preforms for subsequent press consolidation. The mechanical, thermal, and tomography results reveal that for the correct manufacturing process parameters, in-situ laminates from can outperform pressed laminates in certain areas and reach 90% of their performance in others. The porosity is also seen to reduce during the manufacturing process, decreasing to 1.1% from the unprocessed prepreg material 2.2%. These results indicate a promising future for the inclusion of in-situ parts in the coming generations of transport vehicles.

原位自动纤维放置部件的性能

尽管是一种相对成熟的制造技术，但由于担心高孔隙率和较差的机械性能，原位自动化纤维放置仍然没有看到用于制造初级和二级飞机结构的工业实施。在本研究中，碳纤维增强PPS作为参考材料，在现场制造了几种层压板，并作为后续压实的预成型件。机械、热学和断层扫描结果表明，在正确的制造工艺参数下，原位层压板在某些领域的性能优于压制层压板，在其他领域的性能达到其90%。在制造过程中，孔隙率也有所降低，从未加工的预浸料的2.2%降至1.1%。这些结果表明，在未来几代运输车辆中包含原位零件是一个有希望的未来。

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
