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.
