Blistering in Carbon-Fiber-Filled Fluorinated Polyimide Academic Article uri icon

abstract

  • AbstractA blistering study was performed on a fluorinated polyimide resin and its carbonfiber composite in an effort to determine the blisterformation temperature and the influence of blisters on composite performance. The fluorinated resin and carbonfiber composite exhibit higher glasstransition (435455C) and decomposition temperatures (above 520C) than similar polyimide resins and their carbonfiber composites currently used. Two techniques were used to determine moistureinduced blister formation. A transverse extensometer with quartz lamps as a heating source measured thickness expansion, as did a thermomechanical analyzer as a function of temperature. Both methods successfully measured the onset of blister formation with varying amounts of absorbed moisture (up to 3 wt%) in the samples. The polyimide resin exhibited blister temperatures ranging from 225 to 362C, with 1.73.0 wt% absorbed moisture, and the polyimide composite had blister temperatures from 246 to 294C with 0.51.5 wt% moisture. The blistering effects of the polyimide composites were found to have little correlation with modulus. POLYM. COMPOS., 2011. 2010 Society of Plastics Engineers
