Embodiment 1

[0029] Such as figure 1 As shown, the pre-processed carbon fiber unidirectional carbon cloth 2 with a width of 400mm is fixed on the unwinding device 1, and then advances forward at a speed of 1m / min through the carbon cloth conductive roller 4, and at the powder spreading device 3, PA6 resin is evenly sprinkled on the upper surface of the carbon cloth. Within 1 minute, the weight of the resin falling on the carbon cloth with an area of ​​400mm×400mm is 48g, and the dusting time is 0.4min. Infrared oven 5, set the heating temperature in the far-infrared oven 5 to 240°C, so that the PA6 resin is fully melted and impregnated with carbon fibers at this temperature. After leaving the far-infrared oven 5, the carbon fiber unidirectional carbon cloth 2 enters the cooling roller 6, and the resin After cooling and flattening, a carbon fiber reinforced thermoplastic prepreg is formed, and finally the prepreg is rolled and formed by the winding device 7, and the obtained carbon fiber re...

Embodiment 2

[0031] Such as figure 1 As shown, the pre-processed carbon fiber unidirectional carbon cloth 2 with a width of 400mm is fixed on the unwinding device 1, and then advances forward at a speed of 1m / min through the carbon cloth conductive roller 4, and at the powder spreading device 3, PA12 resin is evenly sprinkled on the upper surface of the carbon cloth. Within 1 minute, the weight of the resin falling on the carbon cloth with an area of ​​400mm×400mm is 48g, and the dusting time is 0.4min. Infrared oven 5, set the heating temperature in the far-infrared oven 5 to 200°C, so that the PA12 resin is fully melted and impregnated with carbon fibers at this temperature. After leaving the far-infrared oven 5, the carbon fiber unidirectional carbon cloth 2 enters the cooling roller 6, and the resin After being cooled and flattened, a carbon fiber reinforced thermoplastic prepreg is formed, and finally the prepreg is rolled and formed by the winding device 7 . The resulting prepregs a...

Abstract

The invention discloses a method preparing carbon fiber reinforced thermoplastic prepreg by a dusting technology. The method comprises the following steps: uniformly spraying thermoplastic resin powder onto unidirectional fabric through a dusting device; carrying out heat melting through a drying oven; and cooling, flattening and rolling for moulding. The carbon fiber reinforced thermoplastic prepreg can be continuously produced, and the method has characteristics of short technological process, excellent product performance and the like.

Description

technical field [0001] The invention relates to a method for preparing a carbon fiber reinforced thermoplastic prepreg, and belongs to the technical field of design and preparation of composite material intermediates. Background technique [0002] Due to the advantages of light weight, high strength, good fatigue resistance, and strong designability, carbon fiber composite materials have been more and more widely used in aerospace, general industry, and sports and leisure fields. Carbon fiber prepreg is the main application form of carbon fiber. It dips the resin matrix onto the fiber or fabric, and stores it as an intermediate material after certain treatment. For decades since the advent of resin-based composite materials in the 1950s, thermosetting resin-based composite materials have been the mainstream development direction. In the 1980s, thermoplastic resins and their composite materials aroused great interest and made great progress. Compared with thermosetting comp...
