Basalt fiber anyone...?

[Herman]

One of my suppliers, Selcom in Italy, now produces basalt knitted reinforcements on a regular basis. It works well. Technical properties are a bit higher, but also chemical properties and thermal properties are better then glass.

It laminates just as well as glass, just be aware that you will not see air bubbles, just like with carbon or aramide.

There's few places I prefer to use roving as a final layer. On flattish surfaces like decks it's smoother texture (without stithing and even spacing btw the fibres) saves some sanding and filler/epoxy.
Everything else is biax..
