摘要： This disclosure provides a polyimide fiber prepared from a dianhydride compound and a diamine compound, wherein said diamine compound is selected from one or more of the compounds represented by the following formulae (I), (II), (III) and (IV). A polyimide fiber is prepared by using a polyimide polymer system having a specific hydroxyl heterocyclic diamine copolymerization structure, and the prepared polyimide fiber has relatively high strength and modulus and is resistant to high temperature. Furthermore, the polyimide fiber prepared by this disclosure is provided with an active group on its surface, thus being easily adhered to various resin matrices, and the composite material prepared has good mechanical properties.
