摘要: 随着航空航天产业的蓬勃发展,我国对高性能碳纤维复合材料的需求日益增长。杂萘联苯聚醚砜酮[Poly (Phthalazine Ether Sulfone Ketone),PPESK]得益于良好的环氧相容性、可加工性和机械性能,具有在碳纤维/环氧树脂复合材料层间增韧方面的良好应用前景。本研究借助静电纺丝技术,实现了PPESK超细纤维毡的稳定制备,并通过层间铺贴、热压,实现了PPESK与T800级碳纤维/高温环氧树脂预浸料的复合。在预浸料层间添加17 g/m2 PPESK超细纤维毡,其复合材料冲击后压缩强度可达391 MPa,表明PPESK对T800级碳纤维复合材料的层间增韧效果较明显。静电纺丝PPESK纤维在碳纤维复合材料增韧领域具有巨大应用潜力。

Abstract: With the vigorous development of China’s aerospace industry, the demand for high-performance carbon fiber composite materials is increasing. Poly (phthalazine ether sulfone ketone) (PPESK) exhibits good epoxy compatibility, processability, and mechanical properties, showing promising prospects in the field of interlayer toughening of carbon fiber/epoxy resin composite materials. In this study, stable preparation of PPESK ultrafine fiber felts was achieved using electrospinning technology, and through interlayer paving and hot pressing, the composite of PPESK with T800 carbon fiber/high-temperature epoxy resin prepreg was realized. When 17 g/m2 of PPESK ultrafine fiber mats were added between the prepregs, the compression after impact of the composite reached 391 MPa, indicating a significant toughening effect for T800 carbon fiber composite materials. Electrospun PPESK fibers have great potential in the toughening carbon fiber composite materials.
