Hi all,
I'm working with the part ( refer pic) that has joggle area. 
After cure, this part easily create a porosity and delam at this area. I believe it is because of the bridging between the first and second ply carbon woven. As in pic, we put peel ply to bleed the excess resin betwen the first and two plies. 
Also in final bag, we cut off the N10 bagging at the radiius to minimize the bridging.But still the result is still inconsistent.

Need help.

Thanks
