摘要：Elastic properties of fiber reinforced composite laminates depend on
   fiber volume fraction and lay-up configuration(number of layers,ply
   angles and thicknesses).In this paper,the stiffness of fiber reinforced
   laminates with limited fiber volume fraction used is maximized by
   optimizing the lay-up and fiber distribution.In the formulation of this
   optimization problem,the design variables are the lamination parameters
   which are used to describe the layup of laminates and the
   characterization parameters which describe fiber volume fraction
   distribution in layers,the objective is the minimum compliance of
   laminates.Several design examples are shown for different rules of
   lay-up and fiber volume distribution.
