Basalt Fiber Roving For SMC Process

Basalt fiber roving is a high-performance material made from natural basalt rock. It is produced by melting basalt at high temperatures and extruding it into continuous fibers. Known for its excellent mechanical, thermal, and chemical properties, basalt fiber roving is widely used in various industries. This material offers a high strength-to-weight ratio, making it lightweight yet durable. It is resistant to extreme temperatures, chemicals, UV radiation, and corrosion, making it suitable for demanding environments. Additionally, basalt fiber roving is non-conductive and provides good vibration damping. Applications include construction materials, automotive components, wind energy, and aerospace industries. As an eco-friendly material derived from a natural and abundant resource, basalt fiber roving is an excellent alternative to traditional materials like steel or fiberglass.

Compatibility with various resins is assured by appropriate sizings.

Basic technologies of basalt roving processing are the following:

● pultrusion,

● filament winding,

● weaving,

● multiaxial fabrics production.

Type:

1.Direct roving is a ready - to - sell continuous one-end strand produced in the drawing process and wound on bobbins with 200 mm or 160 mm internal diameter.The main advantage of direct roving is zero catenary and excellent appearance.

That is the reason why direct roving is used for production of fabrics and geogrids, as well for production of pultruded profiles and rebar. For other applications customers may need roving with much higher tex, comparing to direct roving, such as 4800 tex.

Some customers can’t use direct roving, because they need roving wound on bobbins with external pool. These products can be produced in form of assembled roving.

2.Assembled roving consists of several single-end strands joined together without twisting on special assembling machine.

It is supplied on bobbins with internal pool (tubeless, 76 mm internal diameter) or external pool (bobbins are wound on a tube with internal diameter of 76 mm and length of 270 mm).
