Research on the mechanical character of calceolate LiOH sorbent in space launching condition

[摘要] This paper researches the mechanical character of calceolate LiOH sorbent used in space station to meet the space launching condition. The performance of calceolate LiOH sorbent in space launching condition is calculated using porous elastic with modified Drucker-Prager model, as there are plenty of micro-voids in the material. And the mechanical experiment is carried out to verify the computed results. Good agreement between the computed results and the experimental observations is obtained, which shows that the mechanical character of calceolate LiOH sorbent can meet the space launching condition.
