| Abstract: | Unsymmetric composite structure is a kind of orthotropic material, and has more designabilities than symmetric composite structure. Those abilities can be used to solve such wing's problems in design as twist diversion, redistribution of load and low efficiency of control. Based upon the results of experiment and calculation of several representative unsymmetric composite laminates, the coupling characteristics of unsymmetric laminate was studied. An airplane wing made of unsymmetric composite structures was designed. And good result was got. |

| Keywords: | composite materials coupling loads distribution control efficiency |
