90s Roll Hoops

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

The 1998-2002 Arrows F1 cars had a solid carbon roll hoop which was separately rivetted and bonded to the top of the monocoque - I assume this was industry standard at the time.

The 2016 Manor MRT05 had a machined titanium roll hoop bonded/rivetted to the tub. I don't know whether the shift is because of greater static tests for the hoop, or if this is how most of the teams do it nowadays.

It's always going to be a balance of strength versus having weight that high up in the car. And there will be budgetary constraints to consider too.

Maybe at least a description how the roll hoops where made and how they were fitted exactly? Anything for more details?

Honda used carbon roll hoops up to the mid-2000s. Can't tell what car it's from as they used that pentagonal shape roll hoop from 2004 until 2008. That would be bonded to the top of the monocoque.
