Hi,

i am making several CFRP plate using prepreg UD, vacuum bagging for testing according to standard for research purposes. Until now, i do not get clear solution to get the bag-face surface similar with tool face (glossy). I am using non-perforated release film, breather and bag after the laminate---oven cured with vacuum pressure. Any idea how to solve this? sanding and polishing? or any missing step? Please help me to achieve quality specimens.
