The invention relates to a method for recycling carbon fibers through plasmas and application, waste composite materials are treated through the plasmas, and the recycled carbon fibers are obtained through cooling and collecting. According to the method, rapid removal of organic components of the waste composite material and rapid and complete recovery of the carbon fiber composite material are realized, long-time heat treatment and use of acid-base and organic reagents are avoided, and the obtained recovered carbon fibers have excellent mechanical properties and can be directly reused for preparation of the composite material. 本发明涉及一种等离子体回收碳纤维的方法及应用，采用等离子体处理废旧复合材料，冷却，收集得到回收碳纤维。本发明实现了废旧复合材料有机成分的快速去除及碳纤维复合材料的快速、完整回收，避免了长时间热处理及酸碱、有机试剂的使用，获得的回收碳纤维具有优异的力学性能，可以直接再利用于复合材料的制备。
