The present works aims to develop multi‐materials such as steel/polymer/steel hybrid system for weight savings in automotive industries. This laminate must be compatible with processing on the industrial line (steel/polymer lamination under 200 °C) and the structure must be flow‐resistant during the paint process curing (200 °C for 30 min). Consequently, a yield stress polymer system based on compatibilized PA11/copolymer of ethylene and octene blends has been developed. The yield stress property (for T > 200 °C) depends on the phase concentration and compatibilization strategy. It is observed that an annealing process (heating treatment for 1 h at 200 °C), simulating the painting process, provides a strong benefit for the polymer/steel properties after aging under humidity conditions.
