CARBON FIBER REINFORCED C-SHAPED STRUCTURE AND MANUFACTURING METHOD THEREOF |
摘要 |
PURPOSE: A manufacturing method of carbon fiber reinforced C-shaped structure is provided to obtain a carbon fiber reinforced C-shaped structure having the improved physical property by winding plural one-directional carbon fiber prepreg units on a cylindrical roller. CONSTITUTION: A sheet of one-directional carbon fiber prepreg is sheared into a tape form and then cut at specific length to prepare plural sheets of one-directional carbon fiber prepreg units(11)(S1). The plural one-directional carbon fiber prepreg units are piled up and wound on a cylindrical roller to form a C-shaped or ring-shaped preform(13)(S2). The preform is wound up as taffeta or satin label prepreg(15)(S3). Then, the preform is heated in a compression mold having a vacuum device to obtain a C-shaped structure(S4). If the preform is molded in the compression mold, the inside of an outer fixing unit has not pores. Thereby, the physical property of the C-shaped structure is improved.
