This project studies the use of a new type of electrospinning technology for synthesizing low thermal conductivity, light weight, and high temperature resistant ceramic fibers could be used in the aerospace field. The project focus on the development of rapid preparation technologyo under high voltage electric field and the performance of ceramic fibers. We will selecte a series of rare earth zirconate inorganic compounds, using the fabrication of fiber precursor sol gel, in the high voltage electric field to prepare the nanometer or submicron ceramic fiber diameter. The ceramic fiber structure, mechanical, thermal and high temperature resistant performance will also be studied.The project owe the originality, and intellectual property, and also shows far-reaching significance for our country aerospace and materials science reserches.
