Embodiment 1

[0033] Embodiment 1, with reference to figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , a kind of equipment used in the preparation method of hybrid fiber reinforced resin-based composite material 3D printing wire, including a first motor 1, the output shaft of the first motor 1 is connected with a first gear 2, the first gear 2 and the second gear 3 meshing, the second gear 3 is installed on the central axis of the fiber spool seat 4, the fiber spool seat 4 includes a fiber spool seat disc 41, two fiber spools 42 are arranged on the outer side of the fiber spool seat disc 41, and the fiber The inner side of the spool seat disc 41 is provided with more than two guide holes 43; the first dry fiber filament 51 and the second dry fiber filament 52 pass through the guide hole 43 and enter the inside of the resin solution tank 13, and the resin solution tank 13 contains Put resin solution 6;

[0034]The inside of the resin solution tank 13 is provided with a drum 7,...

Embodiment 2

[0042] Embodiment 2, a method for preparing hybrid fiber-reinforced resin-based composite material 3D printing filaments, the equipment used is the same as that of Embodiment 1 except that the structure of the fiber spool seat 4 is different, including the following steps:

[0043] 1) if figure 1 , Image 6 As shown, there are 3 fiber spools 42 and 3 guide holes 43 on the fiber spool seat 4, and the second dry fiber filaments 52 of two carbon fibers and the first dry filament 51 of a glass fiber are respectively wound clockwise onto the fibers. On the spool 42, the second dry fiber filament 52 and the first dry fiber filament 51 are respectively passed through the three guide holes 43 on the fiber spool seat 4. Since the dry fiber filament is in a tense state, the dry fiber filament will be transmitted A certain pulling force is given to the fiber spool 4, so that a clockwise moment will be formed for the fiber spool seat 4, and the dry fiber thread enters the inside of the r...

Abstract

The invention provides a preparation method of a hybrid fiber reinforced resin matrix composite 3D printing wire. Different fiber tows wound on a fiber spool penetrate through guide holes in the center of a fiber spool seat correspondingly, the guide holes through which different kinds of fiber filaments penetrate are different, the fiber spool seat rotates to drive the different fiber dry filaments close to one end of the fiber spool seat to rotate around the center of the fiber spool seat, and due to the fact that the other ends of the fiber dry filaments do not rotate, a twisted hybrid continuous fiber tow can be formed; the twisted hybrid continuous fiber tow penetrates through a roller in a resin solution tank and then penetrates through a glue scraping hole in the resin solution tank, redundant resin is scraped off, and the pre-soaked twisted hybrid continuous fiber tow is obtained; and the pre-soaked twisted hybrid continuous fiber tow is subjected to shaping through a shaping neck mould, cooling and winding through a pre-soaked material winding wheel, and finally the hybrid fiber reinforced resin matrix composite 3D printing wire is obtained. The wire can be directly used for a 3D printer, the advantages of all fibers are brought into play, and the performance of a formed part is improved.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a method for preparing a 3D printing silk material of a hybrid fiber-reinforced resin-based composite material. Background technique [0002] Hybrid fiber-reinforced resin-based composites refer to composite materials that reinforce the same resin matrix with two or more fibers. With some other special properties, it overcomes the shortcomings that a single material cannot meet multiple performance requirements; in addition, the diversity of fibers also increases the designability of composite materials and greatly expands its application range. [0003] 3D printing technology is based on a digital model, through the use of bondable materials such as metal powder or plastic linear wire, in a layer-by-layer printing or layer-by-layer selective bonding method to construct rapid additive materials. Manufacturing Technology. 3D printing consumable...
