碳纤维多尺度增强体的研究进展

介绍了碳纳米管、石墨烯、碳纳米纤维等碳纳米材料修饰的碳纤维多尺度增强体的构筑方法（化学气相沉积法、化学接枝法、电化学沉积法、上浆剂复合法和“grafting to”法）及其对复合材料界面力学性能的影响机理.针对碳纤维多尺度增强体的优势和不足,指出需通过界面设计进一步提高碳纤维与碳纳米材料之间的作用强度,氧化石墨烯/碳纤维复合增强体及其对复合材料性能的增强机制是下一步研究的焦点,连续生产碳纤维多尺度增强体也将成为重要的发展方向.

Research progress in multi-scale reinforcement of carbon fibers

Carbon fiber multi-scale reinforcements modified by carbon nanomaterials like carbon nanotube, graphene, and carbon nanofiber, could be achieved through methods such as chemical vapor deposition, chemical grafting, electrochemical deposition, composite sizing, and ＂grafting to＂. The effect of carbon fiber multi-scale reinforcements on the mechanical properties of interface of composites was also reviewed. According to the advantages and disadvantages of carbon fiber multi-scale reinforcements, the interaction strength between carbon fiber and carbon nanomaterials should be improved through the design of the carbon fiber/carbon nanomaterials interface. Graphene oxide/carbon fiber multi-scale reinforcements and its enhancement on the composite properties will be the focus of future research. The continuous preparation of carbon fiber multi-scale reinforcements will also become an important developing direction.
