Moisture Absorption of Epoxy Matrix Composites Immersed in Liquids and in Humid Air.

Abstract

Moisture absorption of graphite-epoxy composites immersed in liquids and in humid air were investigated. The moisture content as a function of time and temperature was measured for three materials: Fiberite T300/1034, Hercules AS/3501-5 and Narmco T300/5208. Tests were performed a) with the materials immersed in No. 2 diesel fuel, in jet A fuel, in aviation oil, in saturated salt water, and in distilled water (in the range 300 to 322 K) and b) with the materials exposed to humid air (in the range 322 to 366 K). The results obtained were compared to available composite and neat resin data. Moisture absorption of a boron-epoxy, graphite-epoxy hybrid composite immersed in humid air and in saturated steam was also measured. (Author)
