High Temperature Prepreg

Our Prepreg is a fabric matrix composite structure for fabricating parts for use in hostile high heat environments. The term "Flexible Ceramic" is used to describe products developed with an inhibited elastic stage and a more fully reactive ceramic stage.  Our Prepreg is a fabric matrix composite structure for fabricating parts for use in hostile high heat environments.  This inorganic material can enter and sustain itself in the “Red Heat Zone” (600°- 1000°C) for extended periods of time.  Our material has passed the ASTM 136-09 Furnace Test rated as "non-combustible".  We have the ability to handle temperatures beyond the limit of organic materials.  A single ply laminate can act as a fire barrier.  When heat is applied, it will produce a protective ceramic skin with a hard rubber backing that has rebound capability to compensate for movement and vibrations.  Laser cutting will produce ceramically sealed edges.

Prepreg Properties and Information:

• Provides fire-proof capability
• For best results, prepreg should be stored @ (18°C/ 0°F),  "B" stage life approximately 1 year.
  
• Outlife - 120 hours @ (21°C/70°F)
  
• Basic Cure cycle  ( 300°F /148°C)     3 hours     185 - 200 PSI
  
• Extended Cure Cycle at higher temperatures will result in higher mechanical properties
  
• Post Cure - allow to return to ambient temperature. 
  
• Note: higher temperature will make material more ceramic.
  
• Operating Temperature:  0 to 2000°F
  
• Bonds well to aluminum, nickel, silica fibers
  
• Co-cure or thermal bond possible.
