Abstract

The invention provides a kind of fibre strengthening polyimide compound material of inorganic nano particle and its producing method. In the premonitory body solution, make aliphatic homopolymerized polyimide, aromatic homopolymerized polyimide, aliphatic copolymerized polyimide and aromatic copolymerized polyimide have in-situ polymerization, then compound with fibre layer in the form of polyamide acid solution, polyimide powder or polyimide beforehand molding membrane obtained by compounding, and adopt heat mould pressing method to produce polyimide compound material strengthened by seriate fibre. It has good apparent performance, toughness, interface intensity and thermal stability. The compounding of inorganic nanometer particles can improve the match ability between organic phase and inorganic phase, and endue polyimide with low heat expansibility, low water absorbability and high thermal conductivity.
