本文报道了将碳纳米管（CNT）薄膜或巴克纸（BP）集成到碳纤维（CF）预浸料复合材料中以制备高碳纳米管含量的杂化复合材料的研究。研究了复合材料层压板的热压灭菌工艺，以了解纳米/微双尺度树脂的流动特性。研究发现，由于BP的超低渗透性和高吸树脂能力，树脂沿透厚方向的出血受到抑制。树脂基质浸渍的BP层比干燥的原始BP层要厚得多，这是由于树脂的高吸收性和膨胀效应。BP/单向碳纤维（UD - CF）复合材料的抗拉强度为2519±101 MPa，模量为149±18 GPa， CF层中局部纤维体积分数为61.46 vol%， BP层中局部碳纳米管体积分数为26.57 vol%。在平面内和通过厚度的电导率方面的显著改善表明了复合材料在结构和多功能方面的应用潜力。
This paper reports on a study of carbon nanotube (CNT) thin film, or buckypaper (BP), integrated into carbon fiber (CF) prepreg composites to create hybrid composite materials with high CNT content. The autoclave process of manufacturing hybrid composite laminates was investigated to gain an understanding of nano/micro dual‐scale resin flow characteristics. The study found that resin bleeding along the through‐thickness direction was inhibited due to extra‐low permeability and high resin absorbing capacity of the BP. Resin matrix‐impregnated BP layers were much thicker than dry pristine BP due to high resin absorbency and swelling effects. The BP/unidirectional carbon fiber (UD‐CF) hybrid composites with local fiber volume fraction of 61.46 vol% in CF ply and local CNT volume fraction of 26.57 vol% in BP layer, had a tensile strength of 2519 ± 101 MPa and modulus of 149 ± 18 GPa. The dramatic improvements in both in‐plane and through‐thickness electrical conductivities demonstrate potential for both structural and multifunctional applications of the resultant hybrid composites.
