Basalt fiber cloth
Basalt fiber cloth
I have been hearing about this cloth "Basalt" on some other forums and was wondering if anyone on here has used it for any of their builds? If so, how was it to work with and would you use it again? The limited information I have been able to find on the web shows its 10x stronger then fiberglass. Thanks for any information.

We have heard about the Basalt cloth as well but that is it for us at the shop!!! Jeff

Re: Basalt fiber cloth
It is certainly NOT 10x stronger than glass. I've looked into it but no huge competitive advantage considering much higher cost

I even asked if it was a typo and meant to say percent? He doubled down and responded with "X"! He claims he'll be posting lab graphs soon. I figured I'd ask here as I know the wealth of knowledge on this forum. Thanks.Evan_Gatehouse wrote: ↑Thu Aug 13, 2020 3:07 pm It is certainly NOT 10x stronger than glass.

It's been a while but was discussed. Two builders on here use/used it previously.

Re: Basalt fiber cloth
I had a sample (3 sq yds) from a South African catamaran builder. IIRC it was about 19 oz sq yd triax. Absolutely marvelous stuff. Easy to wet out, absolutely loves epoxy. conforms well to curves, minimal fraying etc. It is probably 3x the cost of glass (here in Canada) but I would have loved to build my whole boat with it. I think it's more common now than it was 9 yrs ago when I started.

If this is correct, about 20% stronger on a weight for weight basis. If the fatigue properties are better, that could also help, but I've seen no data on that.
Your supplier may have been comparing a Basalt epoxy layup to a chopper gun polyester layup. That might get close to a 10x increase especially on a long term comparison. (Chopped glass has only about 10% of it's ultimate strength if fatigue over millions of cycles of use is to be considered. Wood epoxy about 50%).

Re: Basalt fiber cloth
You are seeing it a bit on the Northern canoe building sites. Ease of wetting out and draping have been mentioned. Some also using with innegra blends for a tough flexible shell. The only places I have seen it lately, it is expensive. It would be great to have a reasonable supplier.
