Glass Woven Roving | Structural Composite Reinforcement , Automotive / Aerospace Solutions
 
 1. Product Introduction
 Glass Woven Roving is a specialized composite reinforcement material made from continuous glass fibers arranged in a non-woven, parallel structure. Engineered for exceptional strength, durability, and versatility, it is widely used in industries requiring lightweight yet robust solutions. Key features include:
  - High Tensile Strength: Tensile strength ranges from 3,000 -5,000 MPa, outperforming traditional materials like steel in weight-sensitive applications.
  - Chemical Resistance: Resists acids, alkalis, and solvents, making it ideal for harsh environments.
  - Thermal Stability: Operates effectively in temperatures up to 400 °C without significant degradation.
  - Electrical Insulation: Non-conductive properties ensure safety in electrical and electronic applications.
  - Lightweight: Density as low as 1.5 -2.0 g/cm³, critical for aerospace and automotive industries.
  
 
 2. Manufacturing Process
  - Raw Material Preparation: 
 - High-purity silica sand, limestone, and alumina are melted at 1,500 -1,600°C to form molten glass.
  
   - Fiber Formation: 
 - Molten glass is extruded through platinum bushings into 10 -25 µm diameter filaments, which are then cooled and solidified.
  
   - Woven Structure: 
 - Filaments are bundled into roving strands and woven into a parallel-laid non-woven mat using specialized looms.
  
   - Surface Treatment: 
 - Coated with vinyl ester or silane-based sizings to enhance resin compatibility and adhesion.
  
   - Quality Control: 
 - ISO 9001-certified testing for tensile strength, thickness uniformity, and chemical resistance.
  
   
 
 3. Usage Precautions
  - Handling: 
 - Wear PPE (gloves, goggles) to avoid fiber irritation; use sharp tools cautiously to prevent breakage.
  
   - Resin Compatibility: 
 - Ensure compatibility with epoxy, polyester, or vinyl ester resins for optimal bonding.
  
   - Curing Conditions: 
 - Maintain 120 -150°C and 0.5 -1.0 MPa pressure during curing to eliminate voids.
  
   - Storage: 
 - Store in dry, ventilated areas; avoid humidity to prevent delamination.
