Monocoque

A monocoque is a fully enclosed structural chassis where the loads are supported by the skin. This could be done by either folding a sheet material (such as aluminum sandwich or sheet metal) or manufacturing components with molding a material (such as CFRP or GFRP).

Generally this design is seen as more challenging compared to a tube frame, but can have considerable performance benefits if done properly.

Design

Approach for designing a monocoque should be in increments. A general practice is to start with a tube frame design which meets FSAE rules and design requirements of the team.

Please stop yelling

Sorry. I just have a really triggering experience of people wanting to make a monocoque, but designing for aesthetics rather then manufacturbility.

Longitudinal Torsion

Consider the monocoque as a cylinder with with cutouts.
