 From experience I can say that many (non-ceramic) RF materials are 
rather soft (most common a mix of PTFE and glass fiber reinforcement) 
and thin.

In the designs that I worked on , we therefore created 4-layer PCBs with 
a core consisting of more rigid material (most times FR4).

Another mix of materials might be PCBs with a solid metal backing used 
for cooling applications (think LED lighting, motor drivers, etc.).

And another application for mixed materials are flex-rigid PCBs.

While the different PCBs types are not explained in detail, the brochure 
from Optiprint has some photos of complex designs:
