I am looking for a word that means "made of artificial materials in the shape of the original material." By this, I mean I'm seeking the name of the process of creating replacement products in cheaper material while keeping the appearance of the original. One example is molding a fireplace out of plastic but retaining the shape and texture of bricks. Another example is making seat covers out of synthetic material like naugahyde but forming it to resemble leather. I am sure I read this word somewhere once, and I appreciate any help you can provide. Thank you for your help.
