Embodiment Construction

[0028] Please refer to figure 1 , the equipment of the present invention includes a creel 1, a yarn guide device 2, a traction and dispersion device 3, a far-infrared heating box 4, an extrusion die head 5, a primary dipping tank 6, a secondary dipping tank 7, a dipping calender roll group 8, Traction winding device 9.

[0029] First, the continuous fiber 10 is installed on the spindle of the creel 1, and then the continuous fiber 10 is drawn into the yarn guide device 2, so that the continuous fiber 10 can be in the same plane and evenly distributed. The continuous fiber 10 drawn into the same plane is sent into the far-infrared heating box 4 through the pulling roller 11 to be preheated at 250 degrees, so that the preheated continuous fiber 10 enters the initial dipping tank 6 . At this time, the extrusion die head 5 extrudes the molten resin and impregnates the continuous fiber 10 in the initial impregnation tank 6 through the first molten resin channel, which is not descr...

Abstract

The invention discloses a method and equipment for producing a continuous fiber-reinforced thermoplastic composite material prepreg tape. In the method, an extrusion die head is used for extruding fused resin, preheated continuous fibers are guided into a primary tank for preliminary impregnation, and then discharge pressure is controlled to enable pre-impregnated continuous fibers to pass through a secondary impregnating tank filled with fused resin to realize a full impregnation process. Therefore, the problems of how to enable the prepreg tape to be fully impregnated and threaded and how to enable joint cleaning to become easy can be solved.

Description

technical field [0001] The invention relates to a preparation method and equipment for a prepreg tape, in particular to a production method and equipment for a continuous fiber reinforced thermoplastic composite material. Background technique [0002] Continuous fiber reinforced thermoplastic composites have excellent mechanical properties, strong processability and stable chemical properties, such as high tensile strength and bending strength, excellent high and low temperature impact properties; Under the impetus, its development and application have been greatly developed, and the corresponding manufacturing technology has been continuously improved and improved. [0003] The current production process of prepreg tape includes solution impregnation, powder impregnation, coating impregnation and melt impregnation. The production process of prepreg tape is generally as follows: 1. The continuous fiber is drawn out from the creel and unfolded, and then sent to the preheatin...
