摘要: 为了解决机翼的扭转发散、载荷重新分布及操纵反效和操纵效率等问题,基于非对称复合材料的各向异性及相对于普通复合材料更好的可设计性,以几种典型非对称复合材料层板的试验及计算为基础研究了非对称层合板的各种耦合特性,并进行了非对称复合材料机翼的设计,得到了满意的结果．验证了非对称复合材料结构在机翼设计中应用的可行性．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.
