Product Data Sheet Revised 09/17/07
Description

L-597 is a modified phenolic prepreg with low heat release properties designed for fast cure cycles in crushed core processing. L-597 is intended to be used as a single ply or multiple ply skin for aramid/phenolic honeycomb in aircraft interior honeycomb sandwich panels.

Advantages of L-597
  • Creates sandwich panels by using the crushed core processing method for high volume applications requiring fast curing times.
  • The L-597 system processes rapidly in most platen presses. With rapid open and close cycles, cure cycles as short as 10 minutes are possible using L-597.
  • L-597 will allow the designer to create complex structure requiring flexible prepreg, capable of conforming to crushed core tooling.
  • Meets stringent FAR burn requirements.
