New Energy

1. Lithium Batteries and Energy Storage Systems

• Flame-retardant partitions/thermal runaway protection layers for battery packs
• High-temperature-resistant insulating sheaths for battery wiring harnesses
• Fireproof and thermal insulation linings for energy storage containers

• Thermal Runaway Suppression: As a battery separator, the fabric’s flame-retardant properties delay heat diffusion (thermal conductivity <0.05W/(m·K)). Combined with aerogel composites, it reduces heat transfer between adjacent batteries by over 90%, meeting UL 94 V-0 flame-retardant standards.
• Enhanced Electrical Conductivity: Carbon fiber conductive yarns in wiring harness shielding layers improve signal transmission stability (impedance <5Ω) while resisting electrolyte corrosion (strength retention rate >95% in pH 1-14 environments).
• Lightweight Design: Energy storage container linings using carbon fiber felt are 60% lighter than traditional ceramic fiber boards, reducing transportation energy consumption and improving installation efficiency (e.g., a 100kWh energy storage module loses over 300kg in weight).

2. Photovoltaics and Concentrated Solar Power (CSP)

• High-temperature-resistant backsheets for photovoltaic modules
• Protective coatings for CSP absorber tubes
• Lightweight structural materials for solar-powered drones

• Weather Resistance Improvement: Photovoltaic backsheets using carbon fiber composite films can withstand 5,000 hours of UV radiation (equivalent to 25 years of outdoor exposure) with a yellowing index <5, outperforming traditional PET backsheets (yellowing index >15).
• Efficient Thermal Management: CSP absorber tubes coated with carbon fiber thermal conductive coatings (thermal conductivity >100W/(m·K)) increase heat absorption efficiency by 15%-20% while withstanding temperatures above 400°C (e.g., in molten salt environments).
• Aviation-Grade Weight Reduction: Solar drone fuselages using carbon fiber weaving have a strength-to-weight ratio of 200MPa·m/kg, 45% lighter than aluminum alloy frames, extending flight endurance (e.g., from 12 to over 24 hours).

3. Hydrogen Energy and Fuel Cells

• Flame-retardant and anti-static coatings for hydrogen pipelines
• Insulating partitions for fuel cell stacks
• Cryogenic thermal insulation layers for liquid hydrogen storage tanks

• Hydrogen Safety Protection: The fabric’s conductive fibers dissipate static electricity from friction during hydrogen leaks (surface resistance <10⁶Ω), while flame retardancy meets ISO 19880-1 hydrogen safety standards to suppress hydrogen fire spread.
• Wide Temperature Range Adaptability: Maintains dimensional stability with an error <0.1% in the range from -253°C (liquid hydrogen) to +200°C (fuel cell operating temperature), outperforming traditional rubber materials (error >3%).
• High-Efficiency Thermal Insulation: Liquid hydrogen tanks using carbon fiber vacuum insulation panels have a thermal conductivity <0.001W/(m·K), reducing the boil-off rate (BOR) from 3% to below 0.5%, improving hydrogen storage and transportation efficiency.

4. Wind Power and Turbine Equipment

• Flame-retardant layers for wind turbine blades (leading edge lightning protection)
• High-temperature-resistant seals for gearboxes
• Corrosion-resistant mooring ropes for offshore wind farms

• Lightning Strike Resistance: Carbon fiber conductive networks embedded in blade leading edges enhance lightning current dissipation efficiency to over 95% (vs. ~70% for traditional aluminum foil), reducing blade cracking risks (e.g., an 80% drop in lightning damage rates for 3MW blades).
• Long-Life Sealing: Gearbox seals using carbon fiber-reinforced PTFE composites resist lubricant corrosion for 100,000 hours—5 times longer than ordinary rubber seals—reducing downtime maintenance costs (annual savings of ~¥200,000 per unit).
• Marine Environment Protection: Offshore wind mooring ropes made of carbon fiber have a tensile strength of 3,500MPa and resist salt spray corrosion (strength retention rate >98% after 5,000 hours of testing), suitable for deep-sea wind farms.

5. New Energy Vehicles and Charging Piles

• Fire blankets for power battery packs
• Shielding materials for high-voltage wiring harnesses
• High-temperature-resistant insulation layers for charging piles

• Battery Safety Enhancement: Carbon fiber fire blankets (1-3mm thick) can withstand 1,000°C flames for over 30 minutes, preventing thermal runaway spread in battery packs (passing GB/T 38031-2023 needle penetration tests).
• Electromagnetic Compatibility Optimization: High-voltage wiring harnesses with carbon fiber braided shielding layers reduce EMI radiation by over 40dB (compliant with CISPR 25 Class 5 standards), avoiding interference with in-vehicle electronics.
• Fast Charging Adaptation: Charging pile internal insulation using carbon fiber paper (temperature resistance 220°C) supports 1,000V high-voltage fast charging (traditional PET insulation only withstands 130°C), increasing charging power density (up to 500kW+).

Future Development Directions

1. Multi-Field Coupling Design (Thermal-Electrical-Mechanical)：Develop intelligent carbon fiber-based materials integrated with temperature sensing (accuracy ±1°C) and stress monitoring to provide real-time fault warnings for new energy equipment (e.g., battery swelling, blade cracks).
2. Bio-Based Circular Economy：Produce carbon fiber from waste biomass (e.g., bamboo fiber) to create a closed loop of "plants→fibers→new energy materials→recycling," reducing carbon emissions by ~2 tons per ton of carbon fiber produced.
3. Extreme Environment Applications：Develop carbon fiber composites resistant to vacuum ultraviolet (VUV) radiation for space thermal control systems in lunar/Martian missions (e.g., thermal insulation layers for Chang'e-7 during lunar nights).
