Design and Fabrication of Lightweight Automotive Parts with Continuous Fiber Composite Using Topology Optimization and Tailored Fiber Placement
This paper presents a design method for continuous fiber composites in three-dimensional space with locally varying orientation distribution, as well as their fabrication method. The design method is formulated based on topology optimization by augmented tensor field design variables. The fabrication method is based on Tailored Fiber Placement technology, whereby the preform is prepared by a CNC embroidery machine. The fiber path is generated from an optimized orientation distribution field. The preform is formed with vacuum-assisted resin transfer molding. The fabricated prototype weighs 120 g, a 70% weight reduction, achieving 3.5x mass-specific stiffness improvement.
