Abstract: The influence of out of autoclave(OOA) process is researched and influencing factor of different prepreg, curing process and sealing ways on the porosity of OOA composite is analyzed. The result shows that the resin film coating method of prepreg has great influence on the porosity of products with OOA process. The porosity of products is lower than that double-sided covering when the resin film is one-sided covering. Increasing temperature platform properly is propitious to the air out before the resin gelated and the porosity of final products is lower than that without temperature platform. Using the sealing way of more material to guide air is propitious to squeezing the air produced in the prepreg folding and volatilizing, which will and finally get products with lower porosity.
