Investigation of the Effects of Humidity Exposure on 3501-6/AS Prepreg Material.

摘要

Humid aging studies of AS/3501-6 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 calorimentry (Dsc) studies. Mechanicl properties of composites fabricated from humid aged prepreg were also determined. (MM).
