Group: Forum Members Posts: 102, Visits: 582	My supplier has something called kevlar honeycomb, as far as I know it is made out of kevlar paper(?) pre-impregnated with phenol resin. It is realyyyy expensive 70euro exl.vat for 2mm x 2550mmx1250mm and 48kg/m^2, he claims that it is the lightest sandwich in the world. I don't have money to buy it, but when I have some $ I will make some reviev of that, this is how it looks like : Here are some more info but unfortunatly in polish, but I quess it is not hard to understand things like dimensions or price http://surfpol.pl/materialy-sandwichowe-menukompozyty-112/honeycomb-aramid-menukompozyty-118.html Do you know anything about it? How strong is it? Is it hard to work with? Is it worth buying? Thanks for your time Wojtek from Poland Bye! ~~~Everytime I hear sound of demoulding part I have eargasm~~~ Edited 12 Years Ago by wojtepanik

That is awesome. How many layers of CF cloth went into the 1 mm skin? And what kind of CF cloth? Same questions for the 2 mm skins.
