Solvay CYCOM® 919 Epoxy Prepreg with Graphite Unitape
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Property data for specimen with Graphite; Weave style: Unitape; Number of piles: 8.16; Average ply thickness: 0.006 in (0.152 mm); Cure pressure: Autoclave-40 psi (0.27 MPa); Cure temperature: 250°F (121°C); Cure time (cool under pressure): 1 hr; Cure rate per minute: 3.5°F (1.9°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. Features & Benefits: Excellent structural properties in solid laminates of moderate thickness Exceptional toughness Controlled flow and high elongation Flame retardant; fire-resistant under FAA-453 Serviceable to 200°F (93°C) No post cure required Curing pressures range from 12 psi (0.084 MPa) vacuum to 100 psi (0.70 MPa) positive pressure 20 day out time at room temperature Information provided by Cytec, subsequently acquired by Solvay.
