LFT Direct Roving : Lightweight Composite Solutions For Automotive And Aerospace
LFT Direct Roving is an advanced long-fiber reinforced thermoplastic (LFT) material engineered for structural applications requiring exceptional strength-to-weight ratios. Combining continuous glass fibers (5–25 mm) with high-performance thermoplastics like polypropylene (PP) or nylon (PA), this product delivers superior mechanical stability, impact resistance, and thermal durability. Designed for direct molding via LFT-D (Direct Long Fiber Thermoplastic) processes, it eliminates intermediate steps, ensuring consistent fiber alignment and maximizing performance in automotive, aerospace, and industrial components.
| Step | Description |
|---|---|
| Fiber Preparation | Continuous glass rovings are drawn and pre-treated with sizing agents for optimal resin bonding. |
| In-Line Impregnation | Fibers pass through a dual-extruder system where molten thermoplastic resin uniformly coats and saturates the fibers. |
| Fiber Cutoff | Pre-impregnated fibers are cut into controlled lengths (12–50 mm) for precise integration into molds. |
| Compression Molding | Fiber-resin strands are placed into molds and cured under heat/pressure to form final components. |
| Post-Processing | Surface treatments (e.g., painting, coating) enhance adhesion and aesthetic finishes. |
Storage: Store in dry, ventilated areas (15–30°C) away from humidity and UV exposure to prevent fiber degradation.
Temperature Limits: Operational range: -40°C to 130°C; avoid prolonged exposure to >150°C unless specified for high-temperature grades.
Chemical Resistance: Compatible with PP, PA, and PBT resins. Avoid contact with strong acids, solvents, or aromatic hydrocarbons.
Handling: Wear PPE (gloves, goggles) to prevent fiber irritation; use sharp tools for cutting to minimize fraying.
| Parameter | Value/Range |
