| Abstract: | On the basis of the formula of buckling load of C/ E composite trellis wound structure under the axial force combined with external pressure,this paper calculates the load carrying capacity for the carbon epoxy composite trellis wound structure. Through choosing non hole structure as objective function,we can obtain an optimum strengthe ning design result. The result gives a good strengthening method to the typical area of the skin with the hole and solves the engineer problem. |
| Keywords: | C/ E composite trellis wound structure Strengthening the load carrying capacity with a hole |
