Hello to all!

I'm new to composites and diving in!

I would like your suggestion on making 2 sided glossy GF plates. 1mm to 6 mm

I did start a test of infusion in between 2 glass panels that are waxed. Am I off track oy not?

What do production shops do?

Thanks

Pre-preg between two sheets of glass works very well too. But you need to make the pre-preg sheet the same size as the glass plates, or use spacers to take up the thickness of the sheet, otherwise you get the uneven pressure situation that Chris was referring too. Also a bit hairy making glass bend. If you use very thick glass and the pre-preg sheet isn't that thick then it may be ok, but atmospheric pressure is heavy! 

Infusion I dont find a great process for it, Chris pretty much covered the reasons why. But on top of that, infusion just loves to make a mess of things like this, you get resin going places you don't really want it to go and it can be a real pain in the ass if you are trying to do it more than once. If I can't use pre-preg as above then I much prefer to do a 2-shot process and make two skins and bond them together.

Well I will need to rethink my plan! It looks like prepreg is the best solution!
