Plasticisation Effect on Thermal, Dynamic Mechanical and Tensile Properties of Injection-Moulded Glass-Fibre/Polyamide 6,6

摘要: Polymer composites of polyamide 6,6 reinforced with short glass fibre were prepared by injection moulding, conditioned under dry, 50% relative humidity and wet. Investigations TGA, DSC, DMA tensile tests conducted. TGA results revealed that loading in PA improve the thermal stability composites. DSC analysis incorporation moisture into matrix resulted a remarkable decrease degree crystallinity. transition temperatures are sensitive to absorption their values move lower temperature upon exposure moisture. Incorporation gives rise significant improvement modulus strength, while strain is reduced. Exposure different environments from dry wet conditions strength modulus, strains decrease.
