Basalt Biaxial Braided Sleeving is a tubular composite reinforcement sleeve manufactured from continuous basalt fiber yarns arranged in a biaxial braided structure, typically oriented at ±45°. It is designed to provide balanced torsional strength, shear resistance, and high-temperature stability in structural composite applications. Made from natural volcanic basalt fibers, this sleeving offers excellent thermal resistance, corrosion resistance, and mechanical durability. It is widely used in automotive, industrial, marine, and high-performance composite structures requiring lightweight and heat-resistant reinforcement.
