Details
Highlights
- Woven 3M™ Nextel™ 720 continuous ceramic oxide fiber
- Can be converted into semi-unidirectional pre-preg
- Very good mechanical properties at high temperatures
- Electrically insulating with good electromagnetic transparency
- Ideal as a ceramic fiber reinforcement for composites
- Non-hygroscopic and non-oxidizing
- Very low shrinkage after thermal cycling
3M™ Nextel™ Fabric EF-20, woven from 720 Grade continuous filament ceramic 3000 denier roving, is designed to withstand continuous temperatures up to 2200oF (1204oC).
3M™ Nextel™ Fabric EF-20 is woven from 3M™ Nextel™ 720 high temperature continuous ceramic oxide roving.Nextel 720 fiber outperforms the useful limits of many other high temperature textiles by being light weight and electrically insulating – and having good thermo-mechanical properties. Nextel structural fabric EF-20 is often used to reinforce ceramic matrix composites (CMC), metal matrix composites (MMC), or polymer matrix composites (PMC). These composites have exceptional strength and stiffness as well as high temperature capabilities. 3M™ Nextel™ Style EF Woven Ceramic Fabrics are designed to meet the toughest thermal, mechanical and electrically non-conductive performance requirements. Applications: Reinforcement for high temperature structural composites Polymer matrix composites (PMC) Metal matrix composites (MMC) Ceramic matrix composites (CMC) High temperature gasket and sealing High temperature fuel cell components
