Hi John, I implemented your suggestions and tried manufacturing. I could eliminate bridging at corners and pinholes but resin is bleeding out of prepreg and the part is having rough surface on inside and outside. I am following the curing cycle recommended by the manufacturer. I am using single layer of bleeder cloth and the vacuum port is connected to the breather on the part. How to minimize resin bleed out during curing?

Thank You Sir.

Thank you so much for your suggestions. I will implement your suggestions and try to manufacture again. Here are the pictures of the manufactured CFRP part

I have trying to manufacture box shaped enclosure for a camera. The mold is female mold. I am draping carbon fiber prepreg inside the mold and applying vacuum bagging method. I am not getting proper finish on the part and there are dry spots at corner edges. The prepreg layers are not compacted properly and gap between layers is observed at corner edges. Please suggest a procedure to achieve good finish without any defects in box shaped parts
