“…From the engineering perspective, the ply drops in tapered composite structures should be avoided or as few as possible to decrease stress concentration and improve structural integrity. A detailed design guidelines are introduced in [15]. The objective function for optimization is formulated as follows: CT10:Ply -drop alternation: Ply drops should be located alternately close and far from the mid plane:…”

“…In recent years, various methods were used by researchers in blending design. One of the outstanding work was presented in [15], a stacking sequence table (SST) based evolutionary algorithm (EA) is developed for the 18-panel blended design [4] with multiple manufacturing constraints. A backtracking method is popular to ensure the blending and manufacturing rules [16][17][18].…”

“…From the above analysis, blending is the main concern of design problem, because a higher blending property/fewer plydrops can decrease stress concentration as well as improve structural integrity. Moreover, the design of composite structures with complicated manufacturing constraints is more difficult [15].…”

Additional Information:• This paper was accepted for publication in the journal Compos- b s t r a c tA novel framework to design tapered composite structures is proposed for buckling analysis with multiple manufacturing constraints, with variables dealt with separately at different levels and manufacturing constraints divided and imposed in each step. The framework is based on two techniques -a sequential permutation table (SPT) method and a global shared-layer blending (GSLB) method; a design concept is extending from an individual panel to the overall structure by improving its blending property. A problem to design an 18-panel tapered composite structure is adopted to study and validate the proposed framework; a detailed design process is executed step by step to demonstrate the improvements of blending property. Multiple manufacturing constraints are analyzed for the obtained optimal solution, which is also compared with previous studies. The high efficiency of the proposed framework implies its potential for design of large-scale composite structures with complex manufacturing constraints.

A multi‐objective integrated optimization framework that considers the manufacturing process in the design of a tapered carbon‐fiber‐reinforced polymer (CFRP) rim structure was established. Firstly, the three‐zone symmetrically stacked CFRP rim structure was proposed and modeled. The bending and radial fatigue and 13° impact of the carbon/aluminum‐assembled wheel composed of CFRP rim and aluminum alloy spoke were analysed. Coupling lay‐up thickness, sequence and angle as design variables, multi‐objective integrated optimization design for the tapered CFRP rim structure was performed through radial basis function neural network surrogate model combined with an elitist non‐dominated sorting genetic algorithm approach. Pareto‐optimal solutions were obtained, and the trade‐off solution was selected through grey relational analysis coupled with entropy weighting method. Finally, the tapered CFRP rim was manufactured through molding and autoclave forming technology. The CFRP rim has a weight saving of 17.2% compared with the previously developed forged magnesium alloy rim of the same size. The bending and radial fatigue and 13° impact performance of the assembled wheel were then validated by corresponding physical test, results of which met GB 36581‐2018 standard.
