Fatigue behavior of laminated glass fiber reinforced polyamide

During fatigue tests, an infrared (IR) camera was also used to monitor the temperature rise in [02/902]s and [04/904]s laminates resulting from mechanical cyclic loading, and to capture the temperature profile associated with the failure area in the specimens. The maximum temperature in [04/904]s laminates was comparable to that of [02/902]s laminates and the final temperature in some of the cross-ply specimens reached 50 °C, which was near the glass transition temperature of the polyamide matrix.
