Fiber placement technologies allow for manufacturing of complex-shaped composite parts with load-adapted fiber orientation. For design of corresponding structures, topology optimization is well-established. However, anisotropic topology optimization approaches are often limited to unidirectional fiber orientations. In truss-like topology optimized structures, the intersections between the individual trusses are subject to multiaxial stress states. For those, a unidirectional fiber orientation is not appropriate and may not be suitable for manufacturing.

用于具有双轴纤维布局的连续纤维增强聚合物结构的各向异性拓扑优化程序，以改进交叉点设计

纤维铺放技术可以制造具有负载适应纤维方向的复杂形状的复合材料零件。对于相应结构的设计，拓扑优化已经成熟。然而，各向异性拓扑优化方法通常仅限于单向纤维方向。在类桁架拓扑优化结构中，各个桁架之间的交叉点受到多轴应力状态的影响。对于这些，单向纤维取向是不合适的并且可能不适合制造。
