Laminating a thick plate
Laminating a thick plate
(OP)
Hello,
I would like to laminate a plate with 10 to 12mm tickness, using rovimat, mat and coremat. Anyone can tell me the appropriate quantity and g/m2 of the materials above mentioned. I will use epoxy resin, the hand lay-up process and a vacuum bag.
Thanks,

Core mat is a bulking material and will contribute very little strength to your layup. Also the dressings on some chopped strand mat materials are, not, epoxy compatable.
Rovimat is a French brand of a material usually known in the USA as: Bi Ply, Fabmat or Combi-Mat. These materials vary in weight from about 800 grammes per sq metre up depending on the application. Example Rovimat 1200 = 400 gm Mat 800 gm woven roving.
Come back with more information and you will get a better answer.

So now you wish to size the plate.
It really does not matter what the weight of the individual plies of glass are, it is the total grammeture of the lay up that counts.
One caution, the heavier cloth weights have a lot of dead area between the interstices of the weave, that is why the mat is used to absorb some of this resin.
It is sometimes better to use more layers of a lighter cloth to achieve the same result.
