讨论极性材料螺旋铺层对层合板刚度的影响，给出了含不对称应力和偶应力的螺旋层合板等效常数与螺旋角的关系，得到螺旋角的适当选择可以显著地提高层合板抗桡刚度的结论。
This paper discusses the effect of spiral laminae of polar materials on the stiffness of laminates and gives out the relation between spiral angle and equivalent elastic constants of the spiral laminates including asymmetric stresses and coupled stresses.It is concluded that the appropriate choice of the spiral angle of laminae can greatly enhance the stiffness of laminates.
