Problems solved by technology

[0005] The purpose of the present invention is to overcome the problems of uneven impregnation and complex production process in the prior art, and propose a device for fiber mixing, which has a simple structure, is easy to operate, and can be applied industrially. In the blending process, the thermoplastic nanofibers are mixed with the reinforcing fibers. During the subsequent molding process, the thermoplastic nanofibers can melt in the nanometer range and impregnate the reinforcing fibers. The impregnation effect will be more effective, which greatly improves the molding process. Infiltration effect of thermoplastic material on reinforcing fibers during the process

Abstract

The application provides a device for fiber blending. The device comprises a yarn frame, a parallel yarn arrangement device and an electrostatic spinning system. The device is improved in that the fiber blending course is completed through an electrostatic spinning manner; and yarn blending of micron-grade reinforced fibers and nano-grade thermoplastic fibers can be achieved. In comparison with the prior art, the device for the fiber blending of the reinforced fibers and the thermoplastic nano fibers provided by the application has the advantages that the structure is simple; operations are easily; and the efficiency of the fiber blending of the thermoplastic nano fibers and the reinforced fibers is greatly increased.

Description

technical field [0001] The invention relates to a mixing device, in particular to a fiber mixing device. Background technique [0002] Fiber-reinforced thermoplastic composites have attracted extensive attention due to their excellent toughness and recyclability. The thermoplastic resin has a high melt viscosity, generally exceeding 100 Pa·s, and it is difficult to infiltrate the fiber. Therefore, solving the infiltration of fibers by resin matrix is ​​a prerequisite for expanding the application of thermoplastic composites. [0003] At present, the blended yarn technology of thermoplastic fibers and reinforcing fibers is dry-blended and pre-impregnated, which is an effective way to solve the impregnation of the above-mentioned plastics on reinforcing fibers. The invention patent application with the application number of 201310324483.6 discloses a blended fabric for thermoplastic fiber reinforced composite materials and its preparation method. The method uses the existing...
