Abstract
The semi-crystalline microstructure of nylon 6/6 is directly related to the shear and thermal history of the material. Injection molding freezes in a set microstructure distribution through the thickness of a quenched sample. The relationship between the amorphous and crystalline domains in nylon 6/6 injection molded samples was explored using DMA, Flash DSC and FTIR analysis. The rate of injection during molding was shown to have the most significant effect on final microstructure distribution through the part thickness. Areas within the test geometries were analyzed to determine if the microstrucfure had formed at conditions above or below the Brill transition temperature, providing insight to the condition of localized polymer melt just prior to quenching.
