Abstract:
The properties of high performance fiber reinforced composite materials are excellent, and they are widely used in aerospace, wind power, marine mining, machinery, electronics and other fields. High performance fiber preform is a reinforcing structural phase of advanced composite materials. Fiber preforms obtained by a variety of ways play an important role in the forming process of composites, affecting composites forming and the infiltration of the matrix materials, and determine the final performance of the composites. In this paper the development of high performance fiber preforms was reviewed. From visual angle of manufacturing methods, weaving, braiding, knitting and nonwoven, processing methods and structure characteristics of high performance fiber preforms were introduced. At the same time, briefly summarized recent research situation and progress in process technology. Finally, the key problems need to be solved in the future were proposed and emphasized.
