碩士 === 逢甲大學 === 紡織工程所 === 95 === In this paper, the carbon fiber composites aircraft rib was fabricated with computational simulation by VARTM. The first step was to find the permeability of perform formed with different number of layers, and observed how the resin flow in the perform. The simulation result between two different setting of resin input gate were compared. The outcome of the simulation could provide the suggestions that about mold designing and VARTM process. It is shown that no matter the outward appearance or the mechanical properties was satisfied. In this process, time could be saved much more than traditional method (try and error). The testing result present that the short beam shear strength was more than 34.48 MPa, the Tg is above 180 ℃, and the average Vf is 50％.
