  Abstract

The stacking sequences of fiber-reinforced composites for optimization of turbine blades with the best performance have become a focus of attention. However, the optimization and design principles of its flexural performance are not yet mature. Referring to the problems in previous work, a 3D finite element flexural model of carbon fiber reinforced composites was established based on the Abaqus/Explicit VUMAT subroutine through the Tsai-Wu failure criterion. The influencing laws and optimization mechanisms of different stacking patterns (e.g., different orientations, number of orientation plies, combination of multiple orientation plies, and symmetry/asymmetry structures) on the flexural properties of the composites were systematically investigated, and corresponding design references for the optimization of stacking patterns were given. The results show that the smaller the value of |罐-45 째| (罐 represents the angle of the orientation ply), the more obvious the stress reduction of the orientation ply, and the orientation ply located in the outer layer is more conducive to the improvement of flexural performance. As the number of orientation plies increases, the flexural strength and displacement increase, but the stability decreases, in which the laminate with 50 % 0 째 orientation plies has the best overall performance. In addition, the stability ranking of the laminate stacking sequences for the same 0 째 orientation ply proportion is: multi-orientation asymmetric > multi-orientation symmetric > single-orientation symmetric. In particular, the [75/02/60/ 30/02/15] laminate has the best overall performance with the flexural strength of 974 MPa and the Y-axis offset of 0.057 mm, and its stability is 66 % higher than that of the [15/02/75]S laminate. Under the same tensile/compressive stresses, the actual stress of the warp/weft in the orientation ply is less than the maximum ideal stress and the stress of Y-axis direction SY 0, which delays the fracture of the orientation ply and causes displacement offset, and the increase of the number of orientation plies will aggravate this effect. The obtained highlighted results can provide valuable references for the design and optimization of stacking patterns of plain fabric-reinforced laminates with high flexural properties.
