Product Description
High Strength Epoxy Direct Roving: Industrial Composite Reinforcement For Demanding Applications
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.
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. |
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.
