Recent Trend in Joining of Metal to Polymer- A Review

The metal-polymer hybrid system is widely used in automobile and aviation sector due to its lightweight characteristics. Besides, it has many advantages such as noise reduction damping. Inclusion of these improve the fuel economy, which eventually results dramatic carbon footprint. One important sandwich panels. These are structural members by transportation industries. Joining polymers metals always a challenge because their large property difference. Traditional joining methods not recommended practice sheet joining. Till now, attempts made join metals. This paper highlights various difficulties defects polymer Moreover, effect process variables also discussed detail. main objective this review find out an efficient for composite establish systematic approach improving quality joints sheets. Key Words: Metal-polymer hybrids, Sandwich sheets, Joining, Welding.
