摘要：采用原位预浸工艺制备碳纳米管(CNT)/双马树脂(BMI)复合薄膜.通过高温催化喷射裂解法生长CNT宏观体,并将其和树脂溶液在滚筒上进行原位复合,初步得到预浸复合体,随后对其进行多层叠加、脱除溶剂、热压固化等操作,得到CNT/BMI复合薄膜.研究了CNT的取向性和质量分数对复合薄膜力学性能的影响.通过偏振拉曼、SEM、TGA等进行表征.当CNT的质量分数为59.8%时,复合薄膜拉伸强度达到1.02 GPa,断裂伸长率为8.59%,复合材料的韧性达到48.9 J/cm^(3).
Carbon nanotube(CNT)shows advantages such as high strength,high modulus and light weight,which can be potentially applied in the aerospace,electronics and other fields.Resin has the characteristics of mature technology,large output and low cost.Therefore,it is necessary to combine the two to prepare composites.In this paper,an in-situ prepreg process was used to prepare CNT/bismaleimide(BMI)composite films.The CNT assembly was grown by the high-temperature catalytic spray pyrolysis method and combined with a resin solution in situ on the winding drum to obtain the prepreg composite.Subsequent operations such as multi-layer stacking,solvent removal,and hot-press curing were performed to prepare a CNT/BMI composite film.The influences of the orientation and mass fraction of CNTs on the mechanical properties of the composite film were studied.Characterization was carried out using polarized Raman spectroscopy,SEM,and TGA.Finally,when the mass fraction of CNTs was 59.8%,the composite film achieved a tensile strength of 1.02 GPa,elongation at break of 8.59%,and toughness of 48.9 J/cm^(3).
