市場擴張的主要驅動力是高溫工業應用領域(特別是冶金和半導體製造中使用的真空爐)以及快速成長的儲能領域的需求不斷成長。燃料電池和釩液流電池等先進能源系統的普及,也對這一成長起到了重要作用,因為這些系統都以這些氈作為關鍵電極組件。美國複合材料製造商協會 (ACMA) 的報告也印證了其在工業領域的重要性:作為這些氈關鍵前驅物的碳纖維,全球需求量將在 2024 年達到 3 億英鎊。然而,該市場也面臨著許多挑戰,包括高能耗的碳化和石墨化製程帶來的高昂製造成本,這可能會影響盈利,並限制其在價格敏感型產業的應用。
儲能技術,特別是先進電池系統的日益普及,是全球碳氈和石墨氈市場的主要驅動力。釩液流電池因其安全性高、循環壽命長,在電網級儲能領域日益普及,而碳氈和石墨氈則被用作關鍵的電極材料。 ESS News通報稱,中國將於2026年1月運作全球最大的釩液流電池電站之一,並於2025年12月31日全面運作,這正反映了上述趨勢。此電站裝置容量為200兆瓦(MW),儲能容量為1000兆瓦時(MWh)。如此大規模的部署凸顯了人們對長期儲能技術的日益依賴,推動了對特殊石墨氈和碳氈的需求。
市場也受到高溫工業製程和爐窯需求成長的顯著影響。碳氈和石墨氈是半導體製造和冶金行業不可或缺的材料,是惰性氣體保護爐和真空爐的關鍵隔熱材料。 2026年3月,Investing.com指出,SGL Carbon面向半導體產業的石墨解決方案部門的調整後EBITDA從上一年度的1.31億歐元下降至2025年的8,110萬歐元,顯示這一特定細分市場持續低迷。儘管如此,整個產業對惡劣環境下耐用隔熱材料的需求依然強勁。此外,Investing.com在2026年3月報道稱,SGL Carbon 2025年的累計銷售額為8.502億歐元。這反映了先進碳材料的整體市場趨勢,並證實了儘管波動較大,但關鍵工業應用領域對這些特殊氈的需求仍然存在。
全球碳氈和石墨氈市場的擴張受到其固有高昂製造成本的顯著限制。這些材料的生產涉及高能耗的石墨化和碳化工藝,不可避免地推高了整體生產成本。因此,這種經濟負擔擠壓了製造商的利潤空間,並限制了其廣泛應用,尤其是對成本敏感的行業。
2025年5月發表於《ACS永續化學與工程》期刊的報告佐證了這一觀點。報告指出,用於電池的合成石墨(另一種高能耗材料)的生產每公斤大約需要消耗11.0千瓦時的電力,僅石墨化過程就需要8.3千瓦時。如此巨大的能源需求導致高昂的營運成本,最終產品昂貴,阻礙了其進一步的市場滲透。儘管石墨和碳氈的性能已被廣泛認可,但這些經濟障礙使得它們難以與更便宜的替代品競爭。持續的營運成本和高昂的初始投資都限制了其在現有和新興應用領域的成長。
產業發展的關鍵趨勢之一是透過改進先進材料來提升性能,製造商致力於開發具有先進功能特性的碳氈和石墨氈,以滿足特定應用的需求。這個過程涉及改善表面性能和結構組成,以滿足新興技術的嚴格要求。例如,SGL Carbon 於 2025 年 6 月推出了 SIGRACELL® GFX4.8 EA,這是一款專為液流電池設計的新型電池氈。該產品融合了 PANOX 和人造絲基碳纖維,從而降低了電阻,增大了表面積,並提高了循環穩定性。這些技術進步使氈成為先進能源儲存系統和超高純度工業流程中不可或缺的組件,最終拓展了其價值和應用範圍。
此外,大型企業大幅擴張產能是另一個關鍵的市場趨勢。這些企業正投資維修現有工廠並新建工廠,以滿足預期需求並擴大市場佔有率。這些投資旨在加強供應鏈網路並最佳化營運績效,尤其是在技術整合和產業快速發展的地區。例如,東海碳素公司於2025年10月宣布了一項企業計劃,擬在2024年前投資超過1.5億美元,在印度和越南等新興市場建設新的生產基地。該計劃預計將使總產能提高25%。這種策略性成長對於滿足先進電池和半導體產業激增的需求至關重要。
The Global Carbon Felt and Graphite Felt Market is anticipated to expand from USD 480.23 million in 2025 to USD 726.37 million by 2031, reflecting a compound annual growth rate (CAGR) of 7.14%. Derived from carbon fibers like rayon or polyacrylonitrile, these non-woven refractory materials are manufactured through carbonization, with graphite felt requiring an additional graphitization step at extreme temperatures. They are highly sought after for challenging industrial applications due to their outstanding electrical and thermal conductivity, minimal thermal expansion, and chemical inertness in non-oxidizing settings.

Market expansion is largely fueled by rising requirements in high-temperature industrial applications, notably vacuum furnaces used in metallurgy and semiconductor production, as well as the growing energy storage sector. The widespread integration of advanced energy systems, including fuel cells and vanadium redox flow batteries that utilize these felts as essential electrode components, plays a major role in this growth. Highlighting this industrial significance, the American Composites Manufacturers Association reported that global demand for carbon fiber-the main precursor for these felts-hit 300 million pounds in 2024. Conversely, the market faces a notable hurdle in the form of substantial manufacturing expenses stemming from energy-demanding carbonization and graphitization procedures, which can hinder profitability and restrict usage in price-sensitive industries.
Market Driver
The growing use of energy storage technologies, especially advanced battery systems, acts as a major catalyst for the global carbon and graphite felt market. Because of their safety and extended cycle life, vanadium redox flow batteries are becoming increasingly popular for grid-scale energy storage, utilizing these felts as vital electrode parts. Demonstrating this trend, ESS News reported that China launched the world's largest vanadium redox flow battery plant in January 2026, which achieved full operation on December 31, 2025, boasting a 200 megawatt (MW) power rating and a 1,000 megawatt-hour (MWh) storage capacity. Such large-scale implementations highlight the rising reliance on long-duration storage technologies, thereby boosting the need for specialized graphite and carbon felts.
The market is also heavily influenced by the escalating need for high-temperature industrial processing and furnaces. As vital insulation materials in inert gas and vacuum furnaces, carbon and graphite felts are indispensable for semiconductor manufacturing and metallurgy. In March 2026, Investing.com noted that SGL Carbon's Graphite Solutions division, catering to the semiconductor sector, experienced a drop in adjusted EBITDA from €131.0 million the prior year to €81.1 million in 2025, indicating ongoing softness in that particular niche. Nevertheless, the overarching industrial demand for resilient insulation in severe environments remains strong. Investing.com further reported in March 2026 that SGL Carbon posted consolidated sales of €850.2 million for fiscal year 2025, illustrating the broader market activity for advanced carbon materials and confirming the sustained, if fluctuating, requirement for these specialized felts in major industrial uses.
Market Challenge
The expansion of the global carbon felt and graphite felt market is notably hindered by inherently steep manufacturing expenses. Producing these materials involves highly energy-intensive graphitization and carbonization phases, which inevitably drive up overall production costs. Consequently, this financial strain compromises the profit margins of manufacturers and limits widespread utilization, especially within sectors that are highly sensitive to material costs.
Illustrating this point, a May 2025 report from ACS Sustainable Chemistry & Engineering highlighted that manufacturing battery-grade synthetic graphite-a material subjected to comparable energy-heavy treatments-uses roughly 11.0 kilowatt-hours of electricity per kilogram, with the graphitization stage alone demanding 8.3 kilowatt-hours. These massive energy needs lead to high operational overhead, resulting in an expensive end product that struggles to achieve deeper market penetration. Such financial hurdles make it difficult for graphite and carbon felts to rival more affordable substitutes, despite their well-recognized superior performance, as both continuous operational costs and substantial upfront investments restrict growth in current and emerging applications.
Market Trends
A major trend in the industry is the sophisticated modification of materials to boost performance, with producers focusing on engineering carbon and graphite felts that possess advanced functional traits for specific uses. This process entails improving surface features and structural compositions to satisfy the rigorous requirements of emerging technologies. Illustrating this, SGL Carbon launched SIGRACELL(R) GFX4.8 EA in June 2025, a novel battery felt tailored for redox flow batteries that merges PANOX- and Rayon-based carbon fibers to deliver reduced electrical resistance, expanded surface area, and enhanced cycle stability. These breakthroughs allow the felts to act as essential elements in advanced energy storage configurations and ultra-pure industrial operations, ultimately broadening their value and range of applications.
Additionally, significant capacity expansions by leading manufacturers constitute another critical market trend, as companies invest in upgrading current sites and building new plants to meet projected demand and capture market share. The goal of these financial commitments is to strengthen supply networks and optimize operational performance, especially in areas undergoing swift technological integration and industrial growth. Demonstrating this strategy, Tokai Carbon revealed a corporate plan in October 2025 detailing an investment of more than $150 million during 2024 to construct fresh production centers in developing markets including India and Vietnam, an initiative expected to boost total manufacturing capacity by 25%. Such strategic growth is vital to accommodate the surging demands of the advanced battery and semiconductor sectors.
