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

The glass plates method seems to work ok for small things but it doesn't do much to control the thickness in a uniform way - and the glass is scary to handle routinely.  The gold standard for plate making is a large heated press which will keep the pressure even - and prepreg. 

For infusion, you can use a caul plate (what one sheet of your glass is) and a shiny mold (the other sheet) but your flow distance will be limited to a meter (in ideal conditions) without core - and even then you may end up with slightly tapered plates from edge to edge.  If you can bury some inter-laminar flow media like G-flow in there or get a fabric with a micro web ply to help with flow you may have better luck too... but at a cost to plate performance.  

How big do you need and what are you using them for?

Well I'm in a learning phase and the size of my plates are small (starting at 24''x24'' or 635mm X 635mm). For the moment I want to start with infusion and go from there! Are their some manufacturer or youtube I can look at to gather more info on heated press for the future.
