Hi so a while ago I've worked on a project using grey poly/carbon twill 
and Soric Lantor infusion medium.

I wasn't that happy about the result coming out of the mould and want to know why, So I won't make the same mistake next time.

1. So my first guess is some air went through the part? but the bag was fully sealed and tested with a drop test of 45min and so on.
No air could have passed through the mould because the mould was totally inside the vacuumbag.

2. mould surface was not perfect giving it orange peel look? The mould was pollished and very shinny so not possible too, I guess.
3. I've used a polyester gelcoat and epoxy infusion resin (reason, Polyester mould, Polyester gelcoat (won't stick to the mould, epoxy would stick way more) and epoxy infusion resin bonds 
    well to polyester so thats why, but maybe there is a reaction between the 2?!

You can watch the small video on how it was made, maybe you can find some errors in the video?! 



Please share you'r ideas i'll be happy to hear every possible theory Smile
