[0003] 1. In this way, generally 1m 2 Only 7-8g of resin glue can be laid on the release paper, and the thickness is about 1um, so the gap between the upper and lower two hot pressing rollers is required to be about 1um, which requires relatively high precision. If it is carbon fiber tow It is difficult to achieve when the resin is thin or the weight of the resin is less; and if some heterogeneous substances are added to the resin glue, it is easy to damage the surface of the roller for a long time, so that th

Abstract

The invention provides a novel carbon fiber prepreg system and a manufacturing method of novel carbon fiber prepreg. The novel carbon fiber prepreg system comprises high-pressure resin nozzles, wherein the high-pressure resin nozzles are symmetrically arranged on the front side and the back side of a carbon fiber bundle, one ends of the high-pressure resin nozzles are connected with a metering device, one end of the metering device is connected with a stock bin, the stock bin communicates with the metering device and the high-pressure resin nozzles in sequence, a first electromagnetic valve isarranged between the stock bin and the metering device, a second electromagnetic valve is arranged between the metering device and the high-pressure resin nozzles, a heating mechanism is further arranged in the metering device, and an adhesive amount adjusting device is further arranged between the high-pressure resin nozzles and the carbon fiber bundle, and is used for adjusting the amount of adhesives sprayed onto the carbon fiber bundle by the high-pressure resin nozzles. According to the novel carbon fiber prepreg system and the manufacturing method of novel carbon fiber prepreg, a two-side spraying structure is adopted for resin infiltration on the carbon fiber bundle, so that the infiltration effect is good.

Description

technical field [0001] The invention relates to the technical field of carbon fiber, in particular to a novel carbon fiber prepreg system and a manufacturing method thereof. Background technique [0002] At present, the method of impregnating carbon fiber tow with resin glue in the prior art is generally by coating resin glue on the release paper, then hot pressing the release paper on the carbon fiber tow, and then tearing the release paper The resin glue is impregnated on the carbon fiber tow by means, but the structure and method of such prepreg have the following problems: [0003] 1. In this way, generally 1m 2 Only 7-8g of resin glue can be laid on the release paper, and the thickness is about 1um, so the gap between the upper and lower two hot pressing rollers is required to be about 1um, which requires relatively high precision. If it is carbon fiber tow It is difficult to achieve when the resin is thin or the weight of the resin is less; and if some heterogeneous ...
