摘　　要：This study explores the mechanical properties of a novel composite material,blending polylactic acid(PLA)with sea shells,through a comprehensive tensile test analysis.The tensile test results offer valuable insights into the material’s behavior under axial loading,shedding light on its strength,stiffness,and deformation characteristics.The results suggest that the incorporation of sea shells decrease the tensile strength of 14.55%and increase the modulus of 27.44%for 15 wt%SSP(sea shell powder)into PLA,emphasizing the reinforcing potential of the mineral-rich sea shell particles.However,a potential trade-off between decreased strength and reduced ductility is noted,highlighting the need for a delicate balance in material composition.The study underscores the importance of uniform sea shell particle distribution within the PLA matrix for consistent mechanical performance.These results offer a basis for additional PLA-sea shell blend optimization,directing future efforts to balance strength,flexibility,and other critical attributes for a range of applications,including biomedical devices and sustainable packaging.This investigation opens the door to more sustainable and mechanically strong materials in the field of additive manufacturing by demonstrating the positive synergy between nature-inspired materials and cutting-edge testing techniques.
