**Abstract**
 In this paper, we study the mechanical behaviours of variable-stiffness composite laminates by setting curvilinear fibre paths. We assume that the fibre orientation angles vary linearly with the reference axis. Based on the different fibre paths, we vary the fibre placement formats and the curvilinear fibre orientation angles of the composite laminates, and then make the simulation for the buckling loads of the three kinds of laminates: the straight fibre placement, the curvilinear fibre placement and the mixed fibre placement. By comparing and analysing, we give the best fibre placement format and the curvilinear fibre orientation angle. The study provides references to the design of variable-stiffness composite laminates. 15 Refs.
