Studying on Porosity Effects of Out of Autoclave Process Composite
The flat sandwich structure with imported T300 grade out of autoclave carbon fiber fabric prepreg was studied.Excluding the influence of curing technology,the processes of laying and packaging to study for influencing factors of the porosity of the parts formed by out of autoclave carbon fiber fabric prepreg were focused on.By setting different process parameters,metallographic analysis and porosity test of the fabricated plate sandwich structure parts,the best process parameters were obtained.The maximum porosi-ty of the parts was reduced from 1.81%before improvement to 0.02%,which greatly reduced the porosity of the parts and thus improved the pass rate of the parts.
