Funfact:
Plasteel was not invented by Wh40k. The term was first used in Dune and in the 1970s a Brazilian car company (Gurgel) patented a composite of fiberglass and steel under that name.
Just because it's one of those terms I often see people talk dismissively about as one of the most silly "technobabbles" WH40k came up with. It didn't.
