Braided Carbon Fiber Biaxial Sleeve is a tubular composite reinforcement sleeve manufactured from carbon fiber yarns arranged in a biaxial braided structure, typically oriented at ±45°. This configuration provides balanced torsional strength, shear resistance, and uniform load distribution in lightweight composite components. Designed for structural reinforcement rather than cosmetic covering, the sleeve conforms easily to round, tapered, or complex shapes and is compatible with resin infusion, vacuum bagging, and other composite manufacturing processes.
