Product Data Sheet

Revised: 10/2/08

Description

L-956 is an excellent high temperature modified epoxy prepreg which exhibits outstanding performance at temperatures up to 400°F (204°C). L-956 is ideally suited for applications on light weight advanced aircraft for fairings, inlet ducting, leading edges, control surfaces, pylons, and radomes. L-956 is moisture resistance and has excellent compatibility with other graphite/epoxy systems.

Advantages of L-956

L-956 has an excellent balance between toughness, high temperature strength and weatherability. L-956 may be co-cured with many of today’s epoxy adhesives systems to form load transfer interfaces. L-956 is also supplied on light weight fiberglass fabric for use as a surfacing ply for graphite/epoxy laminates and facesheets to improve their damage tolerance.
