The combination of metals and carbon fiber reinforced polymer (CFRP) composites to fabricate thin-walled tubes has excellent energy absorption potential. Introducing origami patterns filling with polyurethane foam can affect the deformation process composite tube, significantly improving its performance. This study investigates characteristics CFRP/metal filled components under quasi-static axial loads through experiments numerical simulations. First, performance metal is analyzed, effect on their examined. It found that exhibit significant improvement in compared individual or CFRP tubes. Additionally, incorporation enhances stability tube improves characteristics. Subsequently, effects design parameters, such as winding angle ratio (10°) circumferential (90°) angles, dihedral pattern, number pattern layers, are studied detail. results show an increase load fluctuations decrease, stable progressive fracture occurs, When 150° layers 5, optimal.
