Distribution of Absorbed Moisture in Graphite/Epoxy Laminates After Real-Time Environmental Cycling

Source

Graphite/epoxy laminate specimens were selected from a previous study which included exposure to temperate and tropical aircraft ground storage environments with weekly supersonic flight temperature profiles. After drying and reexposure with heavy water vapor, nuclear reaction analysis was used to measure the distributions of absorbed moisture in sectioned specimens. The effects of thermal spikes on the distributions and comparisons with a history-dependent diffusion model are described.
