A new fiber made from volcanic rock has made all the typical fantastic claims.
Of course, there are no actual physical properties offered.
"Virgin" fiber strength equal to carbon fiber. What does virgin mean?
The strength is equal to carbon fiber (claim) - but what fiber?
The elasticity or youngs modulus is greater than glass - but that's significantly lower than carbon, I guess.
The density is higher than carbon which means it's strength to weight is lower.
Better resistance at high and low temperatures that glass or carbon - resistance to what?
Lower price/ kilo - but what is it? 5% less? 1%less? Since the density is greater do you actually get less material?
Also some good claims:
Impact resistance equal to aramid
High thermal, electrical and acoustical insulation properties - compared to what?
And of course they are building a boat that is the best in the world.
Well I was going to give a link, but it is gone from Yahoo.
The manufacturer: Our products https://www.isomatex.com/categorie/our-products.html
Anyone have real information rather than advertisement?
Sorry for being negative, but 35 years of looking for new materials only to find that the announcements are carefully crafted to cover up problems makes me suspicious.
If it really was so good they would have no reason not to provide the actual properties and comparisons.
