Dear All,

I could not find any relevant information on this topic, which is why I am reaching out for advice.

I am attempting to infuse composite tubes and have 3D-printed a mold using a soluble polymer to facilitate easy removal at the end of the process. I have also developed a method to keep the fibers (tested with both glass and carbon) tightly positioned during the infusion. Additionally, I have found a way to secure the peel ply and the vacuum bag effectively.

However, I am encountering an issue: when applying vacuum, wrinkles form in the bag due to the multiple turns of the fibers, as I am trying to create a multi-layered tube.

Has anyone faced a similar challenge or has any suggestions on how to mitigate this problem?

Best regards,
Raf
