Monocoque and spaceframe joining

[Cosmin09]

Hello Guys,

I am designing a formula student type car. My problem is that I don't know exactly how to join the rear part of the car, which is space frame and the front part which is a monocoque ( not sure if it is going to be aluminium or composite. I would depend on the budget, but I hope it is going to be carbon fiber ). What is the best way to direct the forces in the frame and put the least stress on the joints? What kind of joint do you recommend ? Any other tips are very welcome.

Thank you,
Cosmin

Loads have to be fed into corners and into panels parallel to the force.

I suggest you review some of the information available from other Formula SAE programs that have used composite frame designs:
