Used as a high-performance reinforcing agent in composite materials, especially in friction products like brake pads and clutch facings, where it enhances mechanical strength and heat resistance. Its fibrous structure improves wear resistance and provides dimensional stability under high temperatures. Also utilized in coatings and plastics to increase tensile strength, stiffness, and thermal conductivity without adding significant weight. Common in aerospace, automotive, and industrial applications requiring durable, lightweight, and thermally stable materials.
