TOPIC NAME INVESTIGATING THE INFLUENCE OF MATERIALS ON THE DURABILITY OF COMPOSITE PRODUCTS IN THE INJECTION MOLDING TECHNOLOGY This graduation project aims to sample two different types of Polyamide (PA6) plastics, including PA6 with 30% glass fiber and PA6 without glass fiber (PA6 0%) The sampling process will be carried out to obtain plastic samples with specific thickness and shape, in preparation for further testing Once the plastic samples are obtained, they will undergo tensile testing to evaluate their strength The tensile test will apply standard pulling forces to the plastic samples and record parameters such as maximum force, elongation, and stiffness By comparing the test results between the two types of PA6 plastics, we can assess and compare the impact of glass fiber on the strength and mechanical properties of the plastic After completing the tensile testing, the samples will be subjected to Scanning Electron Microscopy (SEM) to study their surface characteristics SEM allows highmagnification imaging of the sample surfaces, providing detailed information about the structure and shape of the plastic By analyzing SEM images, we can observe and evaluate the distribution of glass fibers in the PA6 30% plastic samples and the differences compared to PA6 0% plastic The obtained results will consist of statistical analysis data, charts, and relevant images For example, these will include tensile strength test parameters, stress-strain diagrams, tensile strength test results, and ultimately, the optimization using ANN and GA The tensile strength test parameters will include maximum force, elongation, and stiffness, which are essential indicators of the mechanical properties of the PA6 plastics These parameters will help evaluate the strength and performance of the samples and enable a comparison between PA6 with and without glass fiber The stress-strain diagrams will illustrate the behavior of the materials under applied forces, providing insights into their elasticity, plasticity, and deformation characteristics iv TABLE OF CONTENTS GRADUATION PROJECT TASKS i COMMITMENT ii THANK YOU iii ABSTRACT iv TABLE OF CONTENTS v LIST
