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 degrees C) and the structure must be flow-resistant during the paint process curing (200 degrees C for 30min). 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%26gt;200 degrees C) depends on the phase concentration and compatibilization strategy. It is observed that an annealing process (heating treatment for 1h at 200 degrees C), simulating the painting process, provides a strong benefit for the polymer/steel properties after aging under humidity conditions.
