The materials used in this study were 5005-H34 aluminum and a self-reinforced polypropylene (Curv, BP). Microscopic examination of the sidewall edge, prior to taking the strain measurements, confirmed the absence of delamination. The results show that the aluminum-Curv laminate exhibits low strain and is not influenced by a change in tool radii, which makes it efficient to solve the problems associated with stamping of traditional monolithic metals.Keywords: Aluminum; Aluminum compounds; Composite materials; Delamination; Interfaces (materials); Laminates; Materials science; Microscopic examination; Polypropylenes; Sandwich structures; Strain; Surface phenomena; Thickness control; Cold forming; Engineering st200410.1023/B:JMSC.0000041707.68685.722015-12-12
