1 Introduction
With the advancement of global energy structure transformation and sustainable development strategies, the demand for high-performance materials in the energy industry, especially in the renewable energy sector, continues to grow. New energy equipment such as wind, solar, marine, and hydrogen energy systems impose higher requirements on materials in terms of strength, durability, lightweighting, and environmental resistance. Traditional metals, glass fiber reinforced plastics (GFRP), and conventional composite materials have limitations in strength-to-weight ratio, corrosion resistance, and maintenance costs, restricting the performance improvement and long-term economic benefits of new energy equipment.
Against this backdrop,CFRT (Continuous Fiber Reinforced Thermoplastic Composite Sheets)has emerged as a novel composite material, demonstrating unique advantages through the combination of continuous fiber reinforcement structures and thermoplastic resin matrices. Its high specific strength, lightweight properties, corrosion resistance, thermoplastic processability, and recyclability make it an ideal material choice for renewable energy equipment. From wind turbine blades to solar brackets, from hydrogen storage devices to offshore energy platforms, CFRT thermoplastic composite sheets exhibit significant advantages in fatigue resistance, environmental adaptability, and structural lightweighting. This paper will explore the applications of CFRT in the energy and renewable energy industry in detail from multiple dimensions, including material properties, typical applications, technical implementation, economic benefits, environmental impacts, and future development trends.
2 CFRT Material Properties and Applicability in the Energy Sector
Structural components of energy equipment typically face working conditions such as high loads, long-term vibration, strong wind, or wave impacts. The core advantage of CFRT thermoplastic composite sheets lies in their continuous fiber reinforcement structure, which provides excellent strength and stiffness at low density. Compared with thermosetting composites, thermoplastic CFRT can achieve rapid processing of complex structural parts through thermoforming, meeting the production needs of complex components such as wind turbine blades, solar frames, and hydrogen storage tanks.
CFRT materials exhibit high tolerance to ultraviolet (UV) radiation, salt spray, and humid-heat environments. Wind power equipment and offshore energy facilities are exposed to strong winds, high humidity, and salt spray for long periods. Traditional metals are prone to corrosion or fatigue failure, while the fiber-reinforced structure and thermoplastic resin matrix of CFRT can effectively resist environmental degradation and ensure structural stability. The low-density characteristic of the material not only reduces overall weight but also decreases the dynamic inertia of wind turbine blades and solar brackets, thereby improving energy efficiency.
The recyclability of CFRT is another major advantage in the new energy field. At the end of the equipment's life cycle, thermoplastic composite sheets can be recycled or reprocessed through heating to achieve circular utilization, aligning with the concept of green energy and the global sustainable development strategy of the energy industry.
3 CFRT Applications in Wind Energy Equipment
Wind turbine blades are the most representative structural components in wind energy equipment. Their design requires both lightweighting and the ability to withstand strong wind loads and long-term fatigue cycles. CFRT thermoplastic composite sheets offer an ideal solution for blade structures. The continuous fiber structure can withstand torsional and bending stresses while maintaining low weight to reduce rotational inertia. The thermoplastic processing property enables blades to be formed into complex shapes during production, optimizing aerodynamic performance and improving power generation efficiency.
In addition to blades, CFRT can also be used for internal support structures of wind turbine towers and components inside nacelles. High-strength and corrosion-resistant CFRT can reduce internal maintenance requirements and improve the reliability of the overall equipment. Compared with traditional GFRP materials, CFRT thermoplastic composite sheets have higher specific strength and toughness, enabling effective absorption of environmental impacts and fatigue loads.
In offshore wind farm applications, the salt spray resistance of CFRT is particularly important. The high corrosiveness of the seawater environment poses significant challenges to traditional metal materials, while CFRT can maintain stable performance for a long time, significantly extending the service life of blades and structural components and reducing long-term operation and maintenance costs.
4 CFRT Applications in the Solar Energy Industry
Solar photovoltaic (PV) brackets and module frames are exposed to sunlight, wind, rain, and temperature changes in outdoor environments for long periods, requiring high weather resistance of materials. CFRT thermoplastic composite sheets have excellent UV resistance and thermal stability, enabling them to maintain mechanical properties and structural integrity over the long term. Lightweight CFRT sheets can reduce the self-weight of brackets, simplify installation processes, lower transportation costs, and provide cost-effective solutions for large-scale PV power plants.
The thermoplastic processability of CFRT allows it to adapt to complex bracket designs, enabling modularization and rapid assembly. This is particularly important for distributed PV systems, which can optimize layout in limited spaces and improve PV module efficiency. In addition, the recyclability of CFRT allows PV brackets to be reused or reprocessed after retirement, meeting the circular economy needs of the renewable energy industry.
In concentrated solar power (CSP) systems, CFRT thermoplastic composite sheets can also be used for collector support structures and reflector backplanes. Their high rigidity, low weight, and corrosion resistance enable equipment to operate stably in high-temperature and outdoor environments, reducing maintenance frequency and the overall weight of the system.
5 CFRT Applications in Marine Energy and Hydrogen Energy Facilities
Marine energy equipment such as tidal generators, wave energy devices, and offshore platforms have extremely high requirements for materials' corrosion resistance, impact resistance, and fatigue resistance. By combining continuous fiber reinforcement structures with thermoplastic resins, CFRT thermoplastic composite sheets can withstand long-term wave impacts and salt spray erosion. Their lightweight characteristic makes offshore facilities more convenient during transportation and installation, reduces the overall load of floating platforms or support structures, and improves the stability of marine energy equipment.
Hydrogen energy facilities such as hydrogen storage tanks and pipeline systems require materials to have high strength and corrosion resistance to ensure safe operation. CFRT thermoplastic composite sheets can maintain structural integrity under high-pressure environments, and complex components can be manufactured through thermoforming and lamination processes to meet the special geometric shape and strength requirements of hydrogen storage equipment. In addition, the recyclability of the material provides a sustainable solution for the full-life cycle management of hydrogen energy facilities.
6 Technical Implementation and Manufacturing Processes
The application of CFRT thermoplastic composite sheets in the new energy industry relies on advanced manufacturing and processing technologies. Compression molding technology can produce large-scale blades, brackets, and structural sheets while ensuring dimensional accuracy and mechanical properties. Automated fiber placement (AFP) technology controls fiber direction through computers, achieving optimized design for specific loads and ensuring structural stability under wind loads, wave loads, and temperature cycles.
The thermoplastic nature enables CFRT to undergo secondary forming and repair, an advantage that traditional thermosetting composites are difficult to achieve. For large-scale wind turbine blades or PV brackets, slight deformation may occur during transportation or installation, and the structure can be quickly repaired through heating, improving construction and operational flexibility.
The modular design concept is fully applied in energy equipment. CFRT sheets can be made into standardized modules, which are rapidly assembled into large-scale structural components. This not only shortens the construction cycle but also facilitates equipment disassembly, transportation, and maintenance. The combination of modular design and recyclability provides strong support for equipment upgrading and circular economy in the new energy industry.
7 Economic Benefits and Environmental Impacts
New energy equipment adopting CFRT thermoplastic composite sheets offers significant economic and environmental advantages. Lightweight structures reduce transportation and installation costs, reduce the pressure of equipment self-weight on the foundation structure, and thus save civil engineering investment. High strength and corrosion resistance reduce equipment maintenance and replacement frequency, improve overall service life, and lower long-term operation costs.
In terms of environmental benefits, the recyclability of CFRT reduces the waste problem after the retirement of new energy equipment, aligning with the concept of green energy development. Compared with traditional materials, CFRT has a lower carbon footprint during production, use, and disposal stages, helping new energy projects achieve carbon neutrality goals. At the same time, lightweight design improves equipment operating efficiency, indirectly reducing energy consumption and greenhouse gas emissions, achieving dual improvements in economic and environmental benefits.
8 Design Freedom and Innovation Potential
The high strength and thermoplastic processing performance of CFRT thermoplastic composite sheets provide great design freedom in the design of new energy equipment. Wind blades, PV brackets, and marine platform components can adopt complex curved surfaces, lightweight trusses, or honeycomb structures to achieve optimized mechanical properties and improved aerodynamic performance. The collaborative design of materials and structures achieves an optimal balance between equipment load-bearing capacity, durability, and weight.
In addition, CFRT materials can be combined with functional coatings, nano-reinforced materials, and intelligent sensors to achieve structural health monitoring, self-healing, and functional integration. In the future, new energy equipment will not only collect and convert energy more efficiently but also achieve real-time monitoring and intelligent operation and maintenance, improving reliability and economy.
