Description

Technical Field

[0002] Carbon fiber reinforced composite materials (CFRP) are widely used in aerospace, energy, transportation, industry and other fields due to their light weight, high strength, good chemical stability and excellent heat resistance. Due to the ultra-high performance retention rate of carbon fiber itself and its long-term inability to degrade in the natural state, the growing demand for carbon fiber and the amount of waste as well as the ultra-high economic effect of recycled carbon fiber, the issue of carbon fiber recycling has come into people's attention. Orienting the recycled fluffy carbon fiber to prepare oriented felt with excellent performance and maximizing the mechanical properties of the recycled carbon fiber itself is one of the ideal and valuable ways to recycle carbon fiber.

[0003] After the recycled carbon fiber is chopped, it needs to be broken up and felted. However, in the prior art, an axial flow fan is usually used to suck the chopped carbon fiber, and the blades of the axial flow fan can break up the carbon fiber during the suction process. However, when the axial flow fan is sucking and breaking up the chopped carbon fiber, the carbon fiber filaments are easily entangled on the rotating shaft, affecting the suction effect and making it difficult to clean, which affects the recycling felting.

[0004] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
