Recycling technology of nano carbon fiber materials

Due to its advantages of high strength, low density, corrosion resistance and high temperature resistance, carbon nanofibers are widely used in aerospace, automobile manufacturing, sports goods, medical equipment and other fields. Therefore, a large number of carbon nanofibers are produced every year. Still in short supply. Extensive use will also produce a lot of waste. Carbon nanofibers are thermosetting materials and cannot be explained. Although they do not cost a lot of landfill, they will pollute the environment to a certain extent. Can carbon nanofibers be recycled?

As carbon nanofibers become more and more widely used, recycling and reuse is a problem that people pay more attention to. As a resource, whether it is natural or artificially synthesized, it should be recycled as much as possible. The resources on the earth are limited. If people keep mining, they will be exhausted one day. Recycling not only saves resources, but also protects the environment.

Through experiments, scientists have developed some methods for recycling nano-carbon fiber waste, such as high-temperature degradation, microwave radiation, etc., but there is an obvious shortcoming. The performance of recycled nano-carbon fiber will be reduced, which is very different from the original. However, it is said that a research association in the United Kingdom has developed an easy, capable of completely separating the epoxy resin in nano-carbon fiber processing parts and recycling high-performance raw materials.

Of course, the above research is only carried out in the laboratory and has not been put into actual production. Because this technology is still immature in many aspects, no one is willing to try it easily.

As for the nano-carbon fiber recycling technology, it is still under constant research. The British researchers mentioned above are also being studied by scientists in other countries. Although no good results have been obtained, there have been preliminary results. I believe that the reuse of carbon nanofibers will be realized in the near future.
