Research on the performance of aluminum cement based high temperature resistant 3D printing materials
A type of aluminum salt water-based 3D printed composite material was prepared using aluminum salt cement with excel-lent high temperature resistance.The mechanical properties of the 3D printed aluminum salt water-based composite material at room temperature and the residual mechanical properties after being subjected to 150,350,550,750 and 950℃were quantitatively ana-lyzed.The evolution process of the material's microstructure was studied using thermogravimetric differential scanning calorimetry(TG-DSC),scanning electron microscopy(SEM),and CT scanning techniques.The results showed that with the increase of tempera-ture,the flexural strength and compressive strength of 3D printed alumina salt water-based composite materials continued to decrease,the weight loss rate increased,and the porosity and cracks of the cement stone structure continued to increase.
