Product Data Sheet Revised 12/21/06
Description

L-926 is a 275°F (135°C) curing phenolic prepreg with excellent fire, smoke, and toxicity properties. L-926 is available on 3K70P carbon fabric or other fabric styles as requested. L-926 is intended to be used as a laminate for high temperature ducts, engine nacelle applications, or in honeycomb sandwich panels.

Advantages of L-926
  • When used with L-310 phenolic adhesive film, L-926 prepreg facings create sandwich panels with high peel strength and high toughness.
  • Processing of L-926 can be easily adapted to most heated presses, autoclaves, or ovens.
  • L-926 is an excellent laminating prepreg when heat resistance to 500°F (260°C) is a requirement.
  • When tested per FAA required OSU test or vertical burns, L-926 will allow the designer to create structure which will meet or exceed these stringent requirements.
