光固化制备极小曲面Al2O3/Al复合结构力学性能研究
Study on mechanical properties of minimal surface Al2O3/Al composite structures prepared by photocuring
摘要
Abstract
In this paper,the minimal surface Gyroid structure ceramic skeleton with volume fraction of 30％was prepared by stereo lithography apparatus(SLA)additive manufacturing,and the interpenetrating Al2O3/Al composite was prepared by metal infiltration.The compressive properties of the Gyroid surface Al2O3/Al interpene-trating composites were compared with those of the honeycomb Al2O3/Al interpenetrating composites.The fracture cross sections of the composites were observed by scanning electron microscopy(SEM),and the compressive failure mechanism of the composites was analyzed.The experimental results show that the compressive failure of the two structural composites mainly occurs at the joint position of the ceramic skeleton and the ceramic-metal interface,and the overall shear angle is 45°.The Gyroid curved structural composite has higher strength and ductility than the honeycomb structural composite due to its smooth and regular topological structure resulting in lower local stress con-centration.The ultimate compressive strength of the Gyroid curved structural composite is 236 MPa,which is 3.4 times that of the honeycomb structure.关键词
