Abstract:
In this paper, the progress in low cost preparation technology of carbon fiber and composite materials from the aspects such as the polymerization of polyacrylonitrile (PAN), preparation of precursors, preoxidization and carbonization process were reviewed. The high cost of carbon fiber composite materials includes not only the cost of carbon fiber, but also the manufacturing cost. The low cost manufacturing technologies of carbon fiber composite materials were briefly introduced, including RTM/RFI, automatic fiber placement, filament winding, pultrusion and electron beam solidification. Finally, it is specifically mentioned that the cost of carbon fibers will be essential for replacing steel. Therefore we should attach great importance to research and development of efficient and low cost new preparation technologies on carbon fibers.
