Lexus and Lamborghini have both created supercars that have a carbon-fiber main frame/tub: Lamborghini Aventador and Lexus LFA.
Do you guys have an idea of what type of mechanical joining they use to put together that CFRP frame/tub ? In pictures I've seen, the frame looks very smooth, and therefore I was wondering if everything was bonded with glue/adhesives.
Sub-question: if there is also bolting involved, do you know if the bolts/rivets are there only for assembly purposes, or if they play a fundamental role in ensuring tensile strength of the joints?
Thanks a lot,
