Core Viewpoint - The rapid development of China's wind power industry is driving significant growth in the demand for wind turbine blades and their core materials, particularly in the wind blade core material sector, which is expected to see its market size increase from 7.35 billion yuan in 2021 to 14.05 billion yuan in 2025, reflecting an 18.1% year-on-year growth [1][6]. Wind Blade Core Material Industry Overview - Wind blades are the core components of wind turbines, responsible for converting wind energy into mechanical energy, which is then transformed into electrical energy [2]. - The manufacturing materials for wind blades include various components such as reinforcement materials, core materials, matrix materials, surface coatings, and structural adhesives [2]. Key Materials in Wind Blade Structure - Core materials, which are crucial for enhancing the structural integrity of wind blades, are typically used in the skin and web of the blades to improve stiffness and reduce weight [3][4]. - Common core materials include balsa wood, PVC foam, and PET foam, with balsa wood being the primary material due to its favorable compressive and shear strength [3][4]. Industry Chain of Wind Blade Core Materials - The upstream of the wind blade core material industry consists of raw materials like balsa wood, PVC, and PET, with a high dependency on imports for balsa wood [4]. - The midstream involves the production and manufacturing of core materials, while the downstream pertains to the application in wind blade manufacturing [4]. Market Size and Growth - The market size for the wind blade industry in China is projected to grow from 29.4 billion yuan in 2021 to 56.2 billion yuan in 2025, driven by increasing installed capacity [5][6]. - The wind blade core material market is expected to expand from 7.35 billion yuan in 2021 to 11.9 billion yuan in 2024, with a forecasted growth to 14.05 billion yuan in 2025 [1][6]. Competitive Landscape - Key players in the wind blade core material industry include both wind blade manufacturers and specialized core material producers, such as Tian Sheng New Materials and Jiangsu Changyou Environmental Technology [8][9]. - Companies are focusing on vertical integration to reduce costs and enhance competitiveness in the market [8]. Development Trends in the Industry - The trend towards larger and lighter wind blades is driving demand for improved core materials, which must meet higher performance and cost-efficiency standards [12]. - PET foam is anticipated to become the mainstream material in the future due to its mechanical strength, lower cost, and recyclability compared to balsa wood and PVC foam [13]. - The demand for wind blade core materials is expected to rise in line with the increasing global demand for clean energy and the growth of wind power installations in China [14].
