Dry patches using weave pattern

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

For me I have yet to confirm, but I talked to the Carbon/Kevlar supplier. Was told my part/mold is too cold, so its causing flow issues with the epoxy.
