Abstract:

Humid aging studies of AS3501-6 prepreg and 3501-6 neat resin at 250C at humidity levels of 0, 31, 51, and 93 RH for time periods of 12, 24, 48, 72, 168 and 336 hrs were carried out. The chemical changes of the resin were followed by infrared spectroscopy IR, high pressure liquid chromatography HPLc, and differential scanning calorimetry Dsc studies. Mechanical properties of composites fabricated from humid aged prepreg were also determined. MM
