please help a poor lamb (combination with monocoque body and frame)

[tigerk]

hello

i am a student from korea

i wonder that how to make a combination monocoque body and frame

(carbon monocoque + 1 inch round frame)


please reply that my question

thanks for your kind

Somehow like that:

Or you could be a little more specific...

There's seriously millions of ways to approach this....have you actually TRIED doing anything yet and are stuck on a point?

As vague a question as this isn't going to be received well

Go take a look at model aircraft or boats to see how they manufacture foam-and-fiberglass structures. It doesn't look that complicated, but there's a reason that FSAE requires a fairly decent analysis of the structure before you build anything but a steel tube-frame.

FWIW, our tube-frames have weighed-in at around 73 lbs the past few years with all brackets, tabs, fabric, floor closeouts, and paint.

Steel, resin, and kerbin?

[tigerk]

What I wanted to say, but of course, there are many ways

but you've used one specific way ,aren't you?

in conclusion

Aluminum monocoque and 1 inch of this material thickness of steel(rear frame)

Let's discuss how to combine these

[Kirk Feldkamp]

You're going to need to make your question more clear if you want to get responses that answer your questions.

If I understand what you're asking, the most common way to attach a tubular subframe to a carbon tub is with bolts and plates. The metal subframe will have tabs welded onto it that have through holes for fasteners. The fasteners will also extend through holes in the tub, and have washers (or other load-spreading plates) and locking nuts. The tub will usually have some crush-proof inserts that are bonded into the tub during the layup process (assuming composite construction). If you're doing an aluminum monocoque construction, the method of attachment won't necessarily change much. With that said, the geometries you use to spread the load to the surrounding structure(s) will probably change.
