A feature-driven topology optimization method preserving component sequence for the 3D printing of CFRP

This paper presents a topology optimization method that preserves component sequence by preserving component sequence for the 3D printing of CFRP. Component sequence preservation is an intrinsic requirement in typical engineering applications, such as additive manufacturing of continuous fibre-reinforced polymer (AM-CFRP) structures, deployable chain-like structures. In this work, the chain-of-bars design variables setting scheme is developed to realize the sequential component ’ s layout, which sets the current bar ’ s end point as the next bar’s start point. A numerical example is given to demonstrate the validity and merits of the proposed method in designing structures preserving component sequence.
