Conditioning effects on thermal and dynamic mechanical properties of injection moulded glass fibre reinforced polyamide 6,6 composites

Polymer composites of polyamide 6,6 reinforced with short glass fiber were prepared by injection molding, conditioned under dry, 50% relative humidity (RH) and wet. Molded specimens were analyzed by thermogravimetric analyzer (TGA), differential scanning calorimetry (DSC) and dynamic mechanical anal...
