This paper presents a multi-material design for a lightweight swing arm of a McPherson suspension. Starting from a stamped steel lower control arm (LCA) of a C-segment vehicle a hybrid arm made of a metal core and two Carbon Fiber Reinforced Plastics covers has been hand sketched, Computer Aided Design designed, and Finite Element Method tested. To fully exploit hybridization potential, it has developed a specific methodology which combines the topological optimization of the metal core, and the 3-phase optimization of the composite covers. Also, an innovative viscoelastic material has been included in the laminates to enhance the damping properties of the arm and a Frequency Response Function analysis has been performed. The results in terms of mass, stiffness and stress distribution have been compared with the original stamped steel LCA and with another hybrid LCA design. The final comparison has shown that with the redesign approach it has been possible to reduce the mass to a greater extent without affecting stiffness performance and stress distribution.

“…Polypropylene (PP) is second most commonly used polymer in industrial applications such as vehicles, marine industries, bicycles, civil necessities, electronic products, and medical instru-ments in form of chemical tanks, pipes, and sheets (Elsheikh et al, 2019a;Pasquini and Addeo, 2005;Rathod et al, 2017;Showaib and Elsheikh, 2020). PP suffers from low mechanical properties which limit its usage (Lin et al, 2015;Yimit et al, 2018). Therefore, it was recommended to add different reinforcement materials to PP to form enhanced composite materials (Abdellah et al, 2018;Dewidar et al, 2010).…”

“…Therefore, it was recommended to add different reinforcement materials to PP to form enhanced composite materials (Abdellah et al, 2018;Dewidar et al, 2010). It is well known that composite materials are a combination of two materials with different physical and chemical properties, which have been extensively investigated in the literature (Elsheikh et al, 2020c;Essa et al, 2021;Fadl et al, 2019;Liu et al, 2020;Wang and Fu, 2019;Xu et al, 2017). The glass-fiber-reinforced PP has been considered as a lightweight and cost-effective composite used in automotive and marine industries (Luo et al, 2018;Rahman et al, A. M. Elhousari et al: The effect of rubber powder additives on mechanical properties 2013; Xu et al, 2019).…”

Abstract. Reinforced thermoplastic composites offer considerable advantages in structural and industrial applications in terms of high specific strength, excellent corrosion resistance, high impact toughness, high specific stiffness, recyclability, cost effectiveness, and design flexibility. Glass fibers (GFs) are the reinforcement material used in polypropylene (PP) composites to enhance PP properties with reasonable cost. To obtain better mechanical properties and decrease the overall cost, recycled rubber powder was used as a low-cost additive to PP/GF composites. The PP and GF, with different weight fractions, were mixed mechanically; then, the mixture was fed into injection molding machine. The PP/GF composites with the highest mechanical properties were selected for further improvements using rubber powder. The obtained samples were tested using tension, impact, and wear tests. The results show that tensile strength of PP/GF composite was improved by 17.8 % by adding 15 wt % GF, and there was a huge drop in impact strength by 80 % for the same GF weight fraction (15 wt %) compared to that of pure PP because of existence of GF. Wear properties and impact strength were improved by adding rubber powder to the composite, with a low weight fraction of 5 wt %, due to the shock-absorbing properties of rubber powder. Micrographs of the fractured sample surfaces revealed the good adhesion between the GF, PP, and the rubber particles.

This paper describes the design procedure to enhance the damping properties of a multimaterial lightweight suspension arm for a C-segment vehicle. An innovative viscoelastic material has been used to join carbon fiber with steel that has a function of passive constrained layer damper and adhesive simultaneously. Therefore, the hybrid technology applied has been focused on reducing the LCA mass, diminishing the steel thickness, and adding a CFRP tailored cover without compromising the global mechanical performance. Particular attention has been paid to the investigation of the dynamic response in terms of vibration reduction, especially in the range of structure-borne frequencies of 0–600 Hz. Two different viscoelastic materials have been evaluated in such a way to compare their stiffness, damping, and dynamic properties. The experimental test results have been virtually correlated with a commercial FEM code to create the respective material card and predict the real behavior of the LCAs (original and hybrid). The experimental modal analysis has been performed and compared on both the arms highlighting a very good correlation between virtual and experimental results. In particular, the hybrid LCA allows an interesting improvement of damping ratio, about 3,5 times higher for each eigenmode than in the original solution.
