Basalt fibres have been around for many years, but their recent commercial availability has been limited. One of exhibitors to make an impact at the recent Composites 2002 show was Sudaglass, who exhibited a range of commercially available basalt fibres, fabrics and nonwovens.
An inert rock found worldwide, basalt is the generic term for solidified volcanic lava and has long been known for its thermal properties, strength and durability.
Until now, spun-fiber production methods have limited its commercial viability, but Sudaglass is the first producer to offer basalt fibers in a 100 percent mineral, continuous-filament form.
Sudaglass basalt roving is available in woven, filled or chopped configurations. It provides high temperature tolerance (maintains integrity at sustained temperatures up to 1800°F/982°C) and offers continuous strand reinforcement for composites to improve integral strength and provide high temperature tolerance.
