The influence of input parameters on the flexural strength for parts obtained by injection

The polymeric materials known a strong development in all fields. In order to improve the mechanical properties of the polymer, composition is reinforced with different materials. Polyamide 6.6 is a natural polymer with a high level of stiffness, hardness and resistance to shock. In this research studies the influence of the input parameters of the injection process on bending resistance for parts made from materials that have the basic polymer polyamide 6.6, using the glass microspheres reinforcement material at the rate of 30%. Experimental research was based on Taguchi method with six factors and two levels of variation. After the samples were obtained the results are focus on: variation of load deformation during flexural tests, XRD analysis, EDAX analysis and scaning with electron microscope (SEM).
