Description

High Strength Epoxy Direct Roving : Industrial Composite Reinforcement For Demanding Applications

​​1. Product Introduction​​

High Strength Epoxy Direct Roving is a specialized composite material engineered for structural reinforcement in high-performance industrial applications. Combining high tensile strength with excellent chemical and thermal resistance, this product features unidirectional epoxy-coated glass fibers arranged in a direct roving configuration. Designed for seamless integration into laminates, it delivers superior mechanical stability, corrosion resistance, and dimensional precision, making it ideal for aerospace, energy, and heavy machinery sectors.

​​2. Manufacturing Process​​

​​Step​​

​​Description​​

​​Fiber Production​​

High-purity E-glass filaments are drawn and coated with epoxy resin using advanced sizing technology.

​​Direct Roving​​

Fibers are aligned axially and bonded into continuous strands without twisting.

​​Curing​​

Controlled thermal curing (120–180°C) activates epoxy cross-linking for rigidity.

​​Quality Assurance​​

Rigorous testing for tensile strength (≥3,000 MPa), adhesion, and thermal stability.

​​3. Usage Precautions​​

  • ​​Storage​​: Keep in dry, ventilated areas (15–30°C) away from humidity and UV exposure.

  • ​​Temperature Limits​​: Operational range: -50°C to 150°C; avoid prolonged exposure to >180°C.

  • ​​Chemical Resistance​​: Compatible with epoxy, polyester, and vinyl ester resins. Avoid contact with strong acids or solvents.

  • ​​Handling​​: Wear PPE (gloves, goggles) to prevent fiber irritation; use sharp tools for cutting.
