301 can be supplied with most commercially available fibers (carbon, quartz, aramid,
S-glass, E-glass, etc.) in both woven form (designated as NB) as well as unidirectional
tape (designated as NCT).
Woven fabrics are available in standard commercial widths up to 60 inches (1.5 m).
Unitape widths up to 39 inches (1 m) are available in standard fiber weights ranging from
70 – 300 gsm (0.014 – 0.060 psf).
Recommended processing conditions
301 is typically cured at 250°F - 300°F (121°C - 149°C) depending on part size and
complexity. With extended cure times, larger scale structures can be cured as low as
195°F-220°F (90°C-104°C). Low, medium and high pressure molding techniques may be
used for curing. Recommended cure cycle is 50 psi (345 kPa); 3°F (1.7°C)/min ramp to
275°F (135°C); hold for 60 minutes, cool to <140°F (60°C).
