3D-Modeling and Simulation of Mechanics Properties Analysis for 3D-Braided Composites CNGV

Through analysis of buckling and stress for a composite cylindrical shell, such technique targets as critical load, strength and stress distribution of 3D-braided composite cylindrical shells are calculated numerically. These results indicate that the effect of buckling to the 3D-braided composite CNGV is indubitable. Based on the 4-step 3-D circular braiding procedure and the theoretical analysis mentioned above, a mathematic model about the structural optimum design of 3D-braided CNGV is proposed. According to this model, the calculated example shows better effects.
