CYCOM 919 is a modified epoxy resin supplied on graphite glass and aramid reinforced fiber. This resin system offers controlled flow and high elongation permitting direct lamination to honeycomb without the use of additional adhesive.

These properties make lightweight sandwich structures possible where impact resistance or a thinner-skin are important design considerations. Examples include radomes subject to rain erosion and aircraft interiors subject to physical abuse. Other applications are secondary aircraft structures and recreation products.

These advanced composites are serviceable over a temperature range of -67°F/-55°C to 200°F/93°C, and can be fully cured at 235°F/112°C to 260°F/127°C in 60 minutes.
