If I wanted to use some kind of cloth,like kevlar,aramid,or something of the sort to make a speaker cone,what kind of resin would be best to combine with it?I‘ve heard of poly-glass,but what is that?when I look it up,it‘s like it doesn‘t exist.Or how bout a pour on polymer hard epoxy resin?Or would epoxies crack?Or what about polyester resins? And whats the difference between those kinds and regular fiberglass resin?I know epoxy dries harder,but is it really that much harder?which would be better for what I want to do?And where can I find it?Thanks a lot!!
