Abstract

Optimization specifically for fiber reinforced plastics (FRP) is
becoming more and more important for creating high-quality composite
structures. Yet, in spite of the increasing use of topology optimization
(TO) within product development, specific TO methods for transversely
isotropic materials like FRP are scarce in research and even more scarce
in practical application. This is amongst other reasons caused by the
challenge of simultaneous optimization of mutually dependent material
distribution and fiber orientations, which poses an obstacle to
established gradient-based optimization routines in terms of iterations
(run time) and gradient formulation. Thus, based on bionic methods, an
efficient, empirical optimization method is proposed to enable fast and
FRP-suitable geometry propositions. Case studies show efficiency and
effectiveness: the new approach offers very fast convergence; plus
perceptible stiffness gains compared to established topology
optimization for isotropic materials.
