Multi-Objective Optimization for Energy Absorption of Carbon Fiber-Reinforced Plastic/Aluminum Hybrid Circular Tube under Both Transverse and Axial Loading

Crashworthiness analysis and multi‐objective optimization of Al/CFRP tubes with induced holes

“…[59] Under a certain tension, the winding machine controlled the rotation of the aluminum tube to drive the CFRP fiber bundle soaked in epoxy resin to wrap continuously on the aluminum tube. Then the wrapped hybrid tube was sealed and placed in the oven for curing according to the curing cycle provided by the epoxy resin manufacturer, [27] as shown in Figure 1. Then the intact Al/CFRP tube was cut into specimens with a length (L) of 100 mm and the Al/CFRP specimens with holes were made by the drilling process.…”

“…Similarly, Kim et al [23] found that the specific EA (SEA) of Al/CFRP hybrid square tube can be increased by nearly 30% under bending load, and Ma et al [24] found that the CFRP/steel tube can increase the SEA by 21.4%. Ma et al [25][26][27] studied the crashworthiness of the Al/CFRP tube under different loading conditions, showing that the Al/CFRP tube has a good application prospect in automotive EA devices. Emadi et al [28,29] found that tempered Al/composite tubes have better crashworthiness than annealed Al/composite tubes, and also studied the relationship between the thickness of Al and the thickness of composite materials, which has a good guiding significance for the design of hybrid tubes.…”

“…In order to improve the crashworthiness of carbon fiber-reinforced aluminum alloy thin-walled structure under bending load, Sun et al [22] carried out multi-objective discrete optimization design for hybrid tube. In order to obtain a metal/composite hybrid tube with good EA under both bending and compression conditions, Ma et al [27] carried out optimization design based on response surface surrogate model and artificial neural network surrogate model. Surrogate model optimization technology has been widely used in the crashworthiness optimization of thin-walled structures.…”

Theoretical prediction model of mean crushing force of CFRP‐Al hybrid circular tubes under axial compression

“…Many experimental and numerical studies have been studied the axial crushing behavior of these tubes up to now. [5][6][7][8][9][10][11][12] Furthermore, it is very essential to establish the theoretical model of energy absorption response for analyzing the performance of energy absorption structure.…”

Crashworthiness analysis of perforated metal/composite thin‐walled structures under axial and oblique loading

“…Kim et al [35,36] conducted an experimental study on the crushing performance and damage expansion form of square tubes of aluminum/ carbon fiber hybrid materials with different thickness and different layup modes under axial low-speed impact load. Ma et al [37][38][39][40] conducted experimental research and numerical simulation on the mechanical properties of aluminum/carbon fiber composite circular tubes in axial, radial, and three-point bending based on the forces that may be applied to the energy absorption box in the actual automobile collision, and further analyzed the failure modes and parameter sensitivity effects of the hybrid tubes under three kinds of forces. It should be noted that the above studies mainly focus on the collision characteristics under pure axial compression or pure transverse bending.…”
