Hello Friends, 

I'm making some parts in carbon fiber (aesthetics) and I know that for this type of product we have some particularities in the manufacturing process. 
Using 3 layers of carbon fiber and epoxy resin with gel time of 290 minutes and pot life of 120 minutes.

My doubts are as follows:

- What's the ideal time to apply the vacuum in my laminate?

- How long should the part stay in the vacuum connected?

A friend told me that for aesthetic parts the ideal would be for me to apply the vacuum a little before the gel time of the resin and for being close to the gel time I can use vacuum above 600 mmHg.

Can anyone help me with this question?

My main problems with Wet Layup + Vacuum Bag were:

Dry parts: - Excessive vacuum or vacuum at the wrong time.

Bubbles / Bridges: Vacuum at the wrong time where the resin was already in the gel time, so the vacuum could not remove them.


Thanks Guys!!
