Product Data Sheet Revised 12/20/06
Description

L-752 is an excellent high temperature modified epoxy prepreg which exhibits outstanding performance at temperatures up to 400°F (204°C). L-752 is ideally suited for applications on light weight advanced aircraft for fairings, inlet ducting, leading edges, control surfaces, pylons, and radomes.

Advantages of L-752
  • L-752 has an excellent balance between toughness, high temperature strength and weatherability.
  • L-752 may be co-cured with many of today’s graphite/epoxy prepreg systems to form load transfer interfaces.
  • L-752 is also supplied on light weight aramid fabric for use as a surfacing ply for graphite/epoxy laminates and facesheets to improve their damage tolerance.
