采用实验室规模的模块化复合材料生产线对单向碳纤维增强热塑性复合材料的加工进行了研究。薄的连续带由12k碳纤维丝束通过使用基于浆料的聚合物悬浮液浸渍的湿浸渍制造。硬件设计以及工艺参数影响磁带的质量和纤维体积含量的磁带，进行了讨论。两种不同等级的聚醚醚酮用于内部制造UD碳纤维增强复合材料胶带。通过压缩模塑由制造的带制备层压材料并进行测试。从短梁强度，弯曲和压缩测试的结果表明，所制造的复合材料的性能匹配的商业上可获得的芳香族聚合物复合材料（APC 2）的性能。该方法的灵活性得到证明，表明它也可以制造单向碳纤维增强聚偏氟乙烯复合材料。
Processing of unidirectional (UD) carbon fibre reinforced thermoplastic composites using a laboratory scale modular composite line was investigated. Thin continuous tapes were manufactured from a 12k carbon fibre tow via wet impregnation impregnated using a slurry based polymer suspension. Hardware design as well as processing parameters influencing the tape quality and the fibre volume content of the resulting tapes, is discussed. Two different grades of polyetheretherketone were used for in-house manufacturing of UD carbon fibre reinforced composite tapes. Laminates were prepared from the manufactured tapes via compression moulding and tested. Results from short beam strength, flexural and compression tests show that the properties of the manufactured composites match the properties of commercially available aromatic polymer composites (APC2). The flexibility of the process is demonstrated, showing that it is also possible to manufacture unidirectional carbon fibre reinforced polyvinylidene fluoride composites.
