3M™ Nextel™ 720 Woven Fabrics EF-11
Ultra High Temperature Mullite Ceramic Fiber Fabric
3M™ Nextel™ 720 Woven Fabrics EF-11 are advanced high-temperature ceramic fiber textiles designed for extreme thermal environments requiring exceptional strength, oxidation resistance, and long-term stability at elevated temperatures.
Produced under the Nextel ceramic fiber product line, EF-11 woven fabrics are widely used in aerospace thermal protection systems, gas turbine insulation, ceramic matrix composites (CMC), and high-temperature industrial applications.
These fabrics are woven using Nextel 720 continuous filament yarn, composed primarily of mullite ceramic fibers (approximately 85% Al2O3 and 15% SiO2).
This mullite-based composition provides excellent thermal stability, superior creep resistance, and improved performance in long-term high-temperature environments, making EF-11 fabrics ideal for aerospace heat shields, structural composites, and high-temperature insulation systems.
With continuous operating capability up to 1200–1400°C, these fabrics are engineered for critical aerospace, defense, and industrial environments where traditional materials cannot withstand extreme heat and mechanical stress.
Product Overview
Nextel 720 EF-11 woven fabrics provide outstanding thermal durability and structural stability in extreme heat conditions. The woven ceramic textile structure ensures excellent dimensional stability, durability, and compatibility with ceramic matrix composite manufacturing processes.
Compared with Nextel 312 and Nextel 440 fabrics, Nextel 720 offers improved creep resistance and long-term thermal stability, making it ideal for high-temperature structural applications and aerospace composite reinforcement.
