Glass Fiber Chopped Strand Mat
Standard Description
Through years of technological development and innovation, CMT has collaborated with renowned domestic glass fiber research institutes and enterprises, taking the lead in domestic glass fiber product machinery production lines. Our products are comparable to international standards, designed in line with European equivalents. Key indicators: Binder residue ≤0.25%, Fiber dispersion uniformity error ≤±3%. We support full-process customization from raw material formulation to finished product testing, providing high-performance reinforcing base materials for wind power, construction, transportation, and other fields.
Product Introduction
This chopped strand mat achieves performance breakthroughs through a four-level precision process system:
Precision Chopping System: Driven by a Siemens servo motor (rotary cutter speed 12000rpm) with Yaskawa frequency converter control, fiber cutting length tolerance ≤±0.3mm, efficiency up to 800kg/h.
Negative Pressure Deposition Technology: 30KW suction fan creates a gradient wind pressure field, enabling 360° random fiber distribution with areal density CV value ≤2.8% (industry average ≤5%).
Intelligent Curing System: Italian Riello burner (440,000 kcal/h) paired with 150mm rock wool insulated drying tunnel, temperature control accuracy ±2℃, curing degree ≥98%.
Environmental Configuration: Pulse dust collection (dust collection rate 99.8%), waste heat recovery system saving 300,000 kWh annually, compliant with environmental standards.
Product Features
Production speed: 450g/m² at 10-14m/min, 300g/m² at 13-17m/min, 100g/m² at 18-20m/min.
Effective mat width: 3200mm.
Weight specifications: 100-600g/m² (customizable upon request). Weight deviation: Average ≤±5%/m², Single value ≤±15%/0.1m². Class A product qualification rate ≥95%.
Mesh belt speed: 10-20m/min, mesh belt deviation ≤±15mm (automatic deviation correction in forming, powder/sizing application, and drying sections).
Unique domestic technology for roving dispersion device in the forming section of chopped strand mat equipment.
Composite Molding Scenarios
New Energy Wind Power: Skins and webs of 10MW+ blades, suitable for vacuum infusion processes.
Construction Engineering: GRC components, thermal-insulated decorative panels, tunnel fireproof linings.
Transportation: Lightweight components for high-speed rail cars, composite laminates for automobile hoods.
Pipeline Anti-corrosion: Linings for chemical storage tanks, anti-corrosion layer reinforcement for marine engineering.
Bathroom Ware: Substrates for acrylic bathtubs and shower trays.
