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