3M™ Nextel™ Structural Fabric EF-20 is woven from 3M™ Nextel™ 720 Grade continuous filament ceramic oxide fiber roving that is designed to maintain strength and flexibility under a variety of extremely high temperature conditions. Our Nextel structural fabric EF-20 outperforms the useful limits of other high temperature textiles for improved performance in demanding applications.

3M™ Nextel™ Structural Fabric EF-20
Medium weight, electrically insulating and flexible
3M™ Nextel™ Structural Fabric EF-20 is a semi-unidirectional fabric from 3M™ Nextel™ 720 high temperature continuous filament ceramic oxide fiber. Due to the properties of Nextel 720 fiber, this product outperforms the useful limits of many other high temperature textiles. It is medium weight, electrically insulating and flexible. Nextel structural fabric EF-20 is often used in combination with ceramic, metal, or polymer matrix materials to form ceramic fiber reinforced composites. These composites have exceptional strength and stiffness and high temperature capability.

3M™ Nextel™ Style EF Woven Ceramic Fabrics are designed to meet the toughest thermal, mechanical and electrical performance requirements. They are heat, flame and oxidation resistant; and chemically resistant, lightweight, electrically insulating and flexible.

Applications
  • Reinforcement for high temperature structural composites
  • Polymer matrix
  • Metal matrix
  • Ceramic matrix
