What Is Aramid-Carbon Mixed Fabric?
Aramid-carbon mixed fabric is a high-performance composite material combining aramid fibers (known for toughness) with carbon fibers (renowned for stiffness). This hybrid structure delivers exceptional strength-to-weight ratios, making it ideal for aerospace, automotive, and ballistic applications. Unlike pure carbon fiber, the aramid component adds impact resistance, while carbon fibers compensate for aramid's lower compressive strength.

Key Components of the Hybrid Fabric
- Aramid fibers: Heat-resistant organic polymers with high tensile strength
- Carbon fibers: Lightweight crystalline carbon structures with superior stiffness
- Polymer matrix: Typically epoxy or thermoplastic resins binding the fibers
aramid-carbon mixed fabric vs kevlar: A Detailed Comparison
When evaluating aramid-carbon mixed fabric vs kevlar, several performance differences emerge. While Kevlar (a type of aramid) excels in cut resistance, the hybrid fabric offers better dimensional stability and compressive strength.
Mechanical Properties Comparison
Property | Aramid-Carbon Mix | Pure Kevlar |
---|---|---|
Tensile Strength | 3,500-4,500 MPa | 3,000-3,600 MPa |
Compressive Strength | 1,200-1,800 MPa | 500-700 MPa |
Impact Resistance | Excellent | Outstanding |
Weight | 1.45-1.55 g/cm³ | 1.44 g/cm³ |
Application-Specific Advantages
- The hybrid fabric maintains shape better under compression than pure aramid
- Carbon fibers reduce creep deformation compared to all-aramid solutions
- Kevlar remains superior for pure ballistic applications due to fiber elasticity
