| Property data for specimen with Kevlar 49 fiber; Weave style: 285; Number of plies: 12; Cure pressure: 35 psi (0.25 MPa); Cure temperature: 250°F (121°C); Bleeder: None; Cure time (cool under pressure): 1 hr; Cure rate per minute: 6°F (3°C) CYCOM® 919 is a modified epoxy resin. 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 is an important design consideration. Examples include radomes subject to rain erosion and aircraft interiors subject to physical abuse. Other applications are secondary aircraft structure and recreation products. CYCOM 919 composites are serviceable over a temperature range of -67°f to 200°F (-55°C to 93°C) and can be fully cured at 235°F to 260°F (113°C to 127°C) in 60 minutes.
