Core Viewpoint - Hunan Zerui New Materials Co., Ltd. has launched two revolutionary high-temperature resistant fibers, Zeralon3A and Zelramic300, at the 2025 China International Advanced Composite Materials Exhibition, marking a significant breakthrough in the domestic silicon carbide fiber industry [1][14]. Company Overview - Hunan Zerui New Materials Co., Ltd. is the only national high-tech enterprise in China that develops and industrializes silicon carbide fibers through doping routes [4]. - The company aims to establish itself as the center of the silicon carbide fiber industry in China and is recognized as a "little giant" enterprise in Hunan Province [4]. - It possesses independent intellectual property rights and a fully controllable production process for silicon carbide fibers, offering the most comprehensive range of doping series silicon carbide fibers in the country [4][6]. Product Launch - The newly launched fibers, Zeralon3A and Zelramic300, are the first high-crystallinity third-generation silicon carbide fibers in China, capable of withstanding temperatures exceeding 1800℃ [1][14]. - These fibers are designed to compete with the Sylramic series from the US COI company and the Tyranno SA series from Japan's Ube Industries [8]. Technical Advancements - The fibers exhibit excellent long-term high-temperature stability, maintaining over 80% strength retention at 1800℃, and are suitable for various composite material preparation processes [8][12]. - The company has established a production line with a capacity of 20 tons per year, significantly increasing production efficiency by 40 times compared to the previous 500 kg/year intermittent capacity [8]. Strategic Importance - The introduction of these fibers is expected to have significant strategic value for China's aerospace, nuclear power, and other industries that require high-temperature, high-strength, lightweight, and cost-effective composite materials [14]. - The company has already collaborated with composite material research units to develop and validate samples for critical components such as turbine outer rings and nuclear fuel cladding tubes [12][14].
