Some 8 years or so ago my friend, entrepreneur and crazed genius inventor, Chippy, showed me some basalt fiberglass fabric. He declared that it had better properties than glass at a fraction of the cost. I understand that the factory burned down and I forgot about it.
Last week I got to meet Mike and Jenn building a cat in Portland, OR. Mike helps build wind generators. They are looking into basalt fabric. I include these links which I have not yet had time to explore. So.
“Check it out. My snowboard has this instead of carbon for stiffness. It is made by Lib Technologies.
I have found references that it is 1/4 the cost of Carbon. Though I have not contacted suppliers. I’ll see if this is true.
Higher UV and heat resistance than carbon
RF Transparent (Military might like this)
non-conductive!!! (better to protect against lightning damage)
environmentally friendly, greenhouse gases released long ago from natural process” Mike
