High Strength Carbon Kevlar Fabric
High Strength Carbon Kevlar Fabric is a premium hybrid reinforcement engineered for maximum structural performance. This fabric utilizes high-strength carbon fiber (≥ 4200 MPa tensile strength) paired with high-tenacity Kevlar fiber (≥ 3100 MPa) in a balanced 2×2 twill weave. The result is a fabric that delivers exceptional tensile strength, stiffness, impact resistance, and damage tolerance — all in one material. Available in 3k, 6k, and 12k carbon tow configurations with 1000d, 1500d Kevlar. Areal weights range from 300 to 800 g/m². This fabric is designed for primary and secondary structural applications in aerospace, automotive, defense, and industrial sectors where the highest levels of performance are required.

Frequently Asked Questions
High-strength Carbon Kevlar uses premium carbon fiber with tensile strength ≥ 4200 MPa (vs. 3500–3800 MPa standard) and high-tenacity Kevlar ≥ 3100 MPa. This provides approximately 15%–20% higher tensile performance, making it suitable for primary structural applications.
High-performance structural epoxy systems (Tg ≥ 180°C) are recommended to fully utilize the fiber's tensile capability. The resin should have strain-to-failure exceeding 2% to avoid premature matrix cracking. Toughened epoxy systems enhance impact resistance.
Yes. The fabric is fully autoclave compatible. Recommended pressure: 5–7 bar; temperature: up to 180°C. The high-strength fibers maintain their properties under elevated temperature processing.
With vacuum bagging: 55% – 58%. With autoclave or compression molding: 58% – 62%. The fabric's weave structure allows high compaction without significant fiber distortion.
