An automotive bumper is disclosed which comprises a shell of injection molded platable grade ABS plastic. The plastic shell is plated with chromium metal and then backfilled by injection of ethylene ionomers. The resultant composite product provides an article which has a metallic appearing external surface and is backfilled with a strong, resilient plastic core. The composite structure has a pleasing appearance, is lightweight and is easy to manufacture. It has substantial structural integrity necessary to serve as impact resistant members on automobiles. The invention also provides a novel process to bond ethylene ionomers to plastic articles of metal-platable grade plastic resin.
