UD tapes, multiaxial fabrics and woven rovings
Kamenny Vek offers various kinds of UD tapes and multi-axial fabrics that can be used for closed moulding technologies like RTM and vacuum infusion. Kamenny Vek works with world-renowned producers of multi-axial fabrics to widen its output range and to satisfy requirements of end-users. Our basalt fabrics are especially important for wind power generator blades and boat hulls production. Low price of basalt non-woven fabrics – nearly the same as for E-glass fabrics – allows to significantly reduce weight of construction keeping the outlay on the level of E-glass materials.
Advantages and benefits
-
Basalt fabrics allow you to produce stronger and stiffer, larger and lighter wind power generator blades keeping outlay on the level of E glass.
-
If the outer gelcoat of your boat is slightly damaged, you can lose it from corrosion of glass fiber composite layer. With our basalt fiber you cannot afraid of such problem.
Product technical information
| Style | Weight range | Resin compatibility |
| Fabrics can be produced using multiple axis (0°, 90°, +45°, -45°), as well as a range of orientations from +20° through to +90° and -20° to -90° combined with chopped mat and multiple layers of veil and/or non-woven materials. | 100 g/m2-3000 g/m2 | Polyester, epoxy, phenolic, vinylester |
Woven fabrics and yarns
Kamenny Vek can provide various types of yarns and woven fabrics. We are open for collaboration in manufacturing of special design fabrics and braided sleeves. Our R&D team is ready to work and satisfy various customer requirements.
Application
- Heat and sound insulations
- Fire protection.
Comparison of basalt and glass fibers
| Thermal properties | Basalt fiber | E glass |
| Application temperature, °C | -260 up to +560 | -60 up to +460 |
| Short-term maximum operation temperature, °C | up to +700 | up to +550 |
| Heat conductivity, W/(m . °K) | 0.031-0.038 | 0.034-0.04 |
-
Basalt fibers have better sound insulation properties than glass fibers. Hence, with interior based on basalt fiber you will feel yourself more comfortable.
-
The dielectric properties of basalt fibers are equal to ones of glass fibers. So, switch from glass to basalt does not change radar transparency of construction.
-
After exposition under 400°C the basalt fibers lose only 20% of their initial strength, while strength of E glass under the same conditions drops substantially – more than 50%.
