dc.description.abstractTHIS STUDY FOCUSES ON THE DESIGN, BEHAVIOR AND EXPERIMENTAL ANALYSIS OF A NOVEL METAMATERIAL, CONSISTING OF AN ASYMMETRIC AUXETIC THREE-DIMENSIONAL STRUCTURE (AATS) INFUSED WITH POLYESTER RESIN. UTILIZING FDM ADDITIVE PRINTING, SAMPLES WERE CREATED WITH CUSTOMIZABLE RESPONSES TO COMPRESSIVE LOADS THROUGH VARIED DESIGN PARAMETERS. THE OBJECTIVE IS TO SURPASS TRADITIONAL MATERIAL BLENDING BY ENHANCING STIFFNESS AND ENERGY ABSORPTION. STRIKING A DELICATE BALANCE, THE AATS ENERGY ABSORPTION PROPERTIES ARE PRESERVED WHILE LEVERAGING THE STIFFNESS OF THE RESIN. DESPITE ITS COMPACT CUBIC FORM, NOT EXCEEDING 27 MM ON EACH SIDE, THIS METAMATERIAL SHOWCASES AMPLIFIED CHARACTERISTICS, BLENDING THE AATS AND POLYESTER RESIN. THE RESULTS HINT AT PROMISING APPLICATIONS ACROSS MILITARY DEFENSE, AUTOMOTIVE, AEROSPACE SECTORS, AND EVEN POTENTIAL REPLACEMENTS FOR ARTICULATED HUMAN SKELETAL COMPONENTS.
