Fiber reinforced polyamide (PA) plays a dominant role in lightweight automotive allocation. The interactions between vibration loading and the simultaneously effect of liquid media are not clear until now. Hence a study was carried out on flat specimens made of short glass fibre reinforced polyamide to determine the damage mechanism by effect of fatigue loading, temperature and automatic transmission fluid exposure. For the estimation different analytic methods such as infrared and polarized light microscopy, DMA in submersible configuration and sorption experiments were used to study the modification of the material by chemical or physical mechanisms. The findings were related to experimental results from fatigue tests.
