Aramid Chopped Fiber: High-Modulus Reinforcement for High-Load Applications

A composite part is only as reliable as its internal reinforcement. Under heavy loads, constant vibration, or extreme temperatures, inferior fibers can lead to warping, cracking, and premature failure. SureTex Aramid Chopped Fiber provides the structural integrity needed to push the limits of your formulations.

Engineered from 100% para-aramid, our chopped strands are precision-cut for uniform dispersion in resin, rubber, and concrete matrices. They integrate seamlessly into existing mixing processes, allowing you to raise a product's mechanical performance without a complete redesign.

Technical Performance Highlights:

High Strength & Modulus: With a tensile strength of ~2900 MPa, it ensures dimensional stability under both sustained and cyclic loading.

Optimal Strength-to-Weight Ratio: The low density (1.44 g/cm³) is critical for weight-saving programs in the aerospace and automotive sectors.

Thermal & Chemical Stability: Retains performance at working temperatures up to 180°C and resists degradation from oils, fuels, and organic solvents.

Minimal Shrinkage: High dimensional stability keeps fibers locked and aligned within the matrix for predictable behavior.

Key Applications:

Resin Systems: Structural reinforcement for mechanical components and high-performance composites.

Rubber Compounds: Enhanced durability and dimensional control for belts, tires, and industrial seals.

Concrete & Mortar: Improved crack control, impact resistance, and energy absorption in specialized construction.

Customization & Specifications: We provide a variety of fiber geometries to match your specific production requirements. While 3mm is our most frequently requested grade, we offer a range of lengths from 3mm to 12mm to optimize dispersion and reinforcement efficiency.

The Result: Integrating SureTex Aramid Chopped Fiber produces stronger, lighter, and longer-lasting composites with minimal changes to your existing formulation.
