Hi,

I am currently making carbon fibre samples of different layers and using different methods.
I have managed to get a really good surface finish with hand lay-up but not with infusion (photo attached).
I saw someone post a similar question on the forum but he was using unidirectional so our problem might be different.



Following the videos you've made for infusion, the surface finish of all may samples are almost entirely dry as if there wasn't enough resin.
You've suggested to reduced the flow speed to allow the resin to get everywhere which I will try very soon.
However, my samples are pretty small (210x160mm) and I'm worried that it won't be enough.
Could the infusion spiral  be completely removed to allow a slower flow process ?

Any advice would be greatly appreciated!

Many thanks,
Philippine

I have tried again removing the spiral line and only putting two thin strips of mesh. I've also closed the vacuum pump line and let the resin flow for a while. It took almost an hour to fill the entire panel. Maybe it wasn't quick enough this time. It still didn't work, I must be doing something wrong but don't know what anymore.
I've start with vacuum bagging tomorrow  as it should give the same properties more or less. Hopefully, that will work.
Thank you all for your answers!
