摘要：Continuous carbon fiber reinforced thermoplastic composites with high mechanical strength can make up for the low-bearing faults of pure resin material and particle reinforced material. At the same time, the physical properties of fiber conduction can meet the structure damage detection and conductive functional requirements. It is seen as one of the advanced technology in thermoplastic 3 D printing field. At present, the material has been gradually used in robot manufacturing, aerospace components manufacturing and so on. This paper introduces the preparation process of continuous fiber reinforced printing filaments and the characterization of mechanical properties, morphology and printing results. It points out that the printing filaments can meet the basic requirements of continuous fiber reinforced printing, which with high fiber orientation is affected by prepreg tension function. In addition, the small diameter filaments have obvious advantages in transportation, printing fabrications and printing effects. It is suggested that continuous fiber reinforced printing is suitable for choosing filaments with the diameter of 0.4 mm or less.
