Cure Procedure

A. Apply vacuum, 22 in. (74 kPa) Hg, and 85 psi (586 kPa) autoclave pressure at ambient temperature.

B. Hold at 80-100°F (27-38°C) for at least 30 minutes, then vent vacuum.

C. Raise temperature to "option."

I. 350°F at 1-5°F (177°C at 0.6-3°C) per minute and hold for 6 hours.

II. 375°F at 1-5°F (191°C at 0.6-3°C) per minute and hold for 4 hours.

D. Cool and remove from autoclave.

E. Postcure either 8 hours at 450°F (232°C) (recommended) or 4 hours at 475°F (246°C). Raise temperature from ambient to 375°F (191°C) at a rate of 5-10°F (3-6°C) per minute and a rate not to exceed 3.3°F (2°C) per minute above 375°F (191°C).
