Newport 307 Description: Newport 307 is a 250 F (121 C) to 300 F (149 C) cure, highly toughened, controlled flow epoxy resin system. Versatile processing, excellent mechanical properties, and long out time make Newport 307 suitable for a variety of applications. Application: The low exotherm properties of Newport 307 make it an ideal product for UAV spars, marine masts, wind blade spar-caps, and other applications where very thick parts are required. It is well suited for low pressure, vacuum bag molding techniques. Newport 307 can be supplied with most commercially available fibers in both woven form (designated as NB) as well as unidirectional tape (designated as NCT), including: Carbon Quartz Aramid S-glass E-glass Other specialty fibers and fabrics Woven fabrics are available in standard commercial widths up to 60 inches (1.5 M). Unitape widths up to 39 inches (1M) are available in standard fiber weights ranging from 125 to 300 gsm. Benefits/Features: Low exotherm, scorch-resistant High toughness Excellent mechanical properties Controlled flow 30 days out time at 70 F (21 C) Available on a wide range of unidirectional fibers and fabrics Recommended Processing Conditions: Newport 307 can be cured at temperatures from 250 F (121 C) to 300 F (149 C), depending on part size and complexity. Low, medium, and high pressure molding techniques may be used to cure Newport 307. Recommended cure cycle is 50 psi (345 kpa), 3 F (1.7 C)/min ramp to 275 F (135 C), hold for 90-120 minutes, cool to <140 F (60 C).
