3-10 daysBasalt Biaxial Braided Sleeving is a tubular composite reinforcement sleeve manufactured from continuous basalt fiber yarns arranged in a biaxial braided structure. The fibers are oriented in opposing directions, typically at ±45°, providing balanced mechanical performance, torsional strength, and improved shear resistance in composite structures.
This basalt braided sleeving is designed for structural reinforcement applications where high temperature resistance, dimensional stability, and corrosion resistance are required.
The sleeve is produced using a controlled braiding process that interlaces basalt fiber yarns in two opposing directions.
