Product Description
LFT Direct Roving: Lightweight Composite Solutions For Automotive And Aerospace
Product Introduction

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.

 
Manufacturing Process
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.
 
Usage Precautions
  • 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.
