The application of carbon fiber composite material in underwater pressure cabin
In order to realize the functional application and lightweight of underwater pressure cabin,the structure and materials of pressure cabin were studied.Carbon fiber composite material and titanium alloy material are used to design and prepare underwater double-layer cylindrical watertight structure pressure cabin.The carbon fiber layer is selected as the lay-up scheme of[90°/90°/0°]s,and the weight of the ballast tank made of pure titanium alloy can be reduced by 23％.Based on the Abaqus finite element analysis software,the strength and stiffness analysis of the ballast tank under the actual working conditions are carried out.The results show that the cylinder meets the strength requirements,and the critical load of the bal-last tank failure is 22.15 MPa by buckling analysis.The physical object was processed,and the material is subjected to pres-sure experiment.The experimental results meet the requirements of strength,stiffness and tightness.The analysis shows that carbon fiber composite material is an important way to make underwater pressure cabin.
