Under the same materials system, technology, temperature and humidity condition, a mould was applied vibration with certain frequency and the other wasn’t applied vibration, the vacuum infusion mold-ing experiments under two different conditions were compared. The effect of vibration on the porosity and mechanical properties of the molding product were analyzed. The results show that under the vibra-tion condition, the infusion time shortens about 24%, the porosity of the molding product decreases by 71.7%, and the tensile strength, tensile modulus, compressive strength and compressive modulus increase by 3.7%, 6.2%, 12.8%, and 6.1% respectively.
