Group: Forum Members Posts: 24, Visits: 69	Hi Forum..! I need to process by hand layup Aramid Fabrics (Kevlar) with epoxy resin. How much resin the Kevlar will need to be wetted? Kevlar Propiertes 360 g/m2 1500 Denier 0/90° Epoxy Laminating epoxy, low viscosity Thanks!

So if your fabric (doesn't matter if its fibreglass or carbon or Kevlar etc) is a 360gsm, then you will need 360g of resin for every square meter of fabric. Plus a little bit of wastage factor for resin in the bottom of your cup, in your brushes, etc. Hi Analdo, We manufacture with glass fibers and resins, with this fibers usually twice of the glass weight is required for resin. We have never reached your 50/50 ratio. Are you sure if it is for all kind of fibers?

Are you using woven glass or chopped strand? Chopped strand is much thirstier and does need twice its weight in resin. Woven glass it should certainly only need it's own weight in resin and it should...

Are you sure about a consistent rule for every fibre material? Different cloth types aside, glass is almost twice as dense as aramid, wich means you would use almost twice as much resin for the same....

I have never noticed any difference in resin consumption between different types of fibre, only different types of cloth, ie. mat, woven, rovings, etc. I always just use the equal weight of resin fo...

I almost never work with carbon in hand lamination process, and hardly use Kevlar at all. Honestly the only things I make using wet layup techniques are bigger moulds. But for resin infusion I can...

With the resin in prepreg being around 40% of the carbon weight, a 1:1 wet lay carbon/resin ratio adds a fair bit of weight to the part. Vacuum bagging using perforated peel ply and at least 2 layers...

If you See trying to achieve prepreg resin content with hand laminating techniques you will almost certainly get a very ugly part. For carbon mixing up resin equal to the weight of cloth seems to be....
