Hello! I made a post last month on the discussion board regarding methods to incorporate a failure line into a carbon fiber rear bonnet. After some advice from oekmont and Hanaldo we attempted to make a small section of the rear bonnet using 3 layers of carbon fiber and 2 layers of lantor soric in between. Unfortunately, it seems that when performing the resin infusion, the area where the decklid curves at ~ 90 degrees, was not in contact with the mold. As a result, the curved area of the part did not take on the shape of the mold and also did not have a nice finish. I believe this issue can be attributed to the fact that 2 layers of lantor soric (2mm each) create a thick part that is slightly difficult to maneuver into the mold.

Please see the photos below for more a clearer image of the issues.

Any advice on how this issue can be overcome will be very much appreciated. Thank you!

Really just a case of working on your bagging technique. You need to focus on those corners, really push them into place until you can feel they are tight against the mould surface, there shouldn't be any movement in the fibres or laminate stack when you press on them firmly. To me it looks like you might be pulling too much vacuum before positioning the bag, as the flat sections will have a higher clamping pressure on them before that radius does which can make it difficult to move things around. It isn't a tight radius at all, so it should be easy to get rid of bridging there, but you should only pull vacuum until the bag is very slack and easy to slide around over the laminate. Then firmly push those radiuses into place, and if they are refusing to stay then you need to hold them there, pull full vacuum, and then release the vacuum again so you can continue getting the rest of it into place. With infusion, this should be the most time consuming part.
