Injection moulded glass-fiber reinforced polyamide 66 composites and unreinforced polymer samples have been characterised during conditioning up to 900 hours in water, ethylene glycol and water-glycol mixture at 50°C and 70°C. All materials showed significant fluid and temperature dependent weight and volume increase. Glass reinforcement significantly reduced the polymer fluid uptake. The absorption of the antifreeze mixture initially follows a simple rule of mixtures of the absorption of the two individual components. However, after absorption of approximately 5% a significantly higher than predicted level of antifreeze absorption was observed. This coincided with a significant increase in the volumetric swelling coefficient. Dynamic mechanical analysis and unnotched impact testing indicated significant changes in composite mechanical performance dependent on conditioning fluid and temperature.
