First comment -

From the looks, that block is just that - a block. It would seem that the primary friction/heat parts of the block will not be replaced, and this is discussed in the article.

It seems like, if we can assume anything from that image, the bearing surfaces and piston sleeves will be part of a secondary "bed plate" that is either fastened/adhered to the plastic block "casing" (if you will).

If I might add another point of discussion to this: What about the availability of self-lubricating plastics? Would they be viable for use in low-speed engine applications (Sub-1000 RPM max) where low heat and power generation are required?

What about applications for air-engines? How about plastic parts for the parts of electric motors that aren't required to be metal by design?

What exactly are the possibilities of manufactured plastic components?
