The combination of structural optimization with the orientation of the reinforcement paths in plates makes it possible to obtain excellent mechanical properties. Added to this, the exploration of the anisotropy of these materials is an effective tool for designing components produced in composites. This optimization can be performed by using a curve that represents the path of the fibers. In these cases, one of the factors that influences the efficiency of the optimization algorithm is the initial placement of the fibers. In this context, with the aim of investigating the influence of the initial directions on the result of the objective function, the optimization of B-splines was carried out in the work, which represented carbon fibers inserted in epoxy resin matrix plates. Thus, seeking to reduce flexibility, three distinct structures with different boundary conditions were optimized using linear programming. In each of them, rectilinear …
