Twill Basalt Fabric

Diagonal Weave for Technical Reinforcement

A diagonal rib structure is used to weave continuous basalt filaments into twill basalt fabrics. This arrangement allows for more yarns per unit area while preserving useful fabric stability since each warp end floats on two or more successive weft threads. The material has a unique appearance because to the diagonal pattern, which makes the structure simple to recognise.
The twill structure offers a different balance between yarn arrangement, fabric weight, and processing properties than a simple plain weave. FTW-220, FTW-270, and FTW-370 technical data are provided for a variety of twill textiles ranging from 150 to 370 g/m². The fabric can also be made in a variety of weights, thicknesses, weave patterns, and weaving techniques based on the specifications of the final use.

Basalt Fibre Performance

The continuous basalt fibres themselves give twill basalt fabric its characteristics. The process of creating basalt fibres involves melting basalt ore between 1400 and 1600 degrees Celsius, followed by the formation of continuous filaments using micro-spinnerets. The resultant fibre has high strength, high modulus of elasticity, excellent heat resistance, strong chemical resistance, and high insulating qualities.
In industrial applications, this material is fire-resistant, non-flammable, and has a good adherence to coatings. Additionally, even at temperatures as high as 1800°F (982°C), it retains structural integrity and resists electromagnetic radiation.

Suitable Composite Processing

Using techniques including hand lay-up, prepreg, pultrusion, SMC/BMC, resin transfer moulding, resin film weaving, and vacuum impregnation, twill basalt fabrics can be integrated into structural composites. Applications in automotive, aircraft, marine, and home appliances, as well as roofing and electrical insulation systems, are identified in the information supplied.
Customers choosing twill basalt fabrics should take into account the final structure and processing technique in addition to the fabric's weight, thickness, and weave. The planned usage of the final composite and the method of forming the reinforcement determine the appropriate requirements.
