DuPont(US:DD) 3 6 Ke·2025-08-23 04:16Core Viewpoint - The article discusses the significance of aramid paper, a high-performance material that has been historically monopolized by Western countries, particularly the United States, and highlights China's advancements in developing its own aramid paper technology, breaking the technological barriers imposed by foreign entities [3][17][28]. Group 1: Aramid Paper Overview - Aramid paper is a high polymer composite material, recognized as one of the three major high-performance fiber materials globally, known as "polyaramid fiber paper" [4]. - The production of aramid paper involves creating aramid fibers, primarily two types: para-aramid (PPTA) and meta-aramid (PMTA), which differ in structure and application [6]. - Aramid paper is characterized by its exceptional strength, being five to six times stronger than steel, and its lightweight nature, making it a valuable material in various applications [9]. Group 2: Historical Context and Development - The United States developed aramid paper during the Cold War for military applications, with DuPont's Nomex and Kevlar becoming prominent materials for insulation and protective gear [9][11]. - China faced significant challenges due to U.S. restrictions on aramid paper technology, which limited its development in multiple sectors, including aerospace and military [18][20]. - Since the 1970s, China has invested in aramid fiber technology, but progress was slow due to a lack of skilled personnel and core technology [22][24]. Group 3: Breakthroughs in China - Professor Zhang Meiyun and her team made significant contributions to the development of aramid paper in China, leading to the introduction of domestically produced aramid paper in 2007 [24][28]. - Professor Hu Jian's team at South China University of Technology achieved advancements in the next generation of aramid paper technology, resulting in products that surpass earlier versions from DuPont [26][28]. - China has now become the fifth country capable of independently researching and producing aramid paper, with applications in various high-profile projects like the Tiangong II space station and the C919 aircraft [28][29]. Group 4: Market Position and Future Prospects - Chinese companies have rapidly gained market share in the global aramid paper industry, with four out of the top five manufacturers being Chinese, collectively holding about 13% of the global market [29]. - The domestic production of aramid materials has led to a significant presence in the global market, particularly in sectors like ballistic protection, where Chinese products dominate [31]. - The advancements in aramid paper technology are expected to drive growth in other high-tech industries, indicating a promising future for the material in various applications [31].
