01 Feb In Focus – Basalt
Basalt is a very unique fibre that is steadily gaining a great deal of interest around the world as a potential alternative to glass fibre. Formed by the rapid cooling of volcanic lava, basaltic rock is quarried, washed, melted and extruded to form basalt filaments, for use in rovings and yarns for a variety of end uses.
Basalt is very similar in chemistry to many glass fibres, but is recognised to have higher temperature and abrasion resistance, and excellent chemical resistance to both acidic, alkaline and saline environments, making it ideally suited to applications such as concrete reinforcement and shoreline applications. It also has a specific strength up to three times that of steel. Step changes in the production methodology now mean that the fibre quality and consistency are excellent, and the material can be twisted or plied for weaving applications into composites and thermal protection.
Multiple Winding has extensive experience of both plying and weaving this novel fibre, and have excellent links with one of the key global basalt producers – Kamenny Vek. Whatever your needs may be, we will find a solution!
