Abstract The pressurized cabin Co-curing technique of carbon fiber/epoxy prepreg for light high-end business jet
AG300 was introduced and studied in this work common background.According to the characteristics of overall molding
pressure cabin for curing furnace, with the aid of DSC to T700G-12K carbon fiber/epoxy presoak curing temperature and
curing degree has carried on the research and analysis, optimization of curing process parameters validated through the
nondestructive testing(NDT) C scan and mechanical testing.The results of the test indicate, The prepreg curing progress of
the pressurized cabin using the gel point temperature of 80℃ for 240min under pressure, then cured at 105℃ for 120min,
finally at 130℃ for 120min. It was the optimal scheme of the experimental group, fewer product defects.
