Basalt technical fabrics are woven from continuous basalt fiber yarnor roving with good permeability and tapability. Their monofilament diametergenerally ranges from 5.5 μ m to 9 μ m, suitable for area of high temperatureresistance and corrosion resistance, and combine quite well with resin,rubber and other organic materials.
