Side Panel

Subteam: AerodynamicsSubsystem: Body Work and NoseAssembly: BodyCars: CR22, CR25, CR26I

Purpose

Closes out the sides of the cockpit, keeps the driver separated from moving and hot components, and continues the external surface between the nose and the engine cover.

Function

Thin CFRP panels fastened to frame tabs. They are part of the aerodynamic outer surface and part of the driver's shielding requirement at the same time.

Design Process

Surface from the CFD geometry. Schedule chosen for handling stiffness and surface quality at minimum weight; these are among the thinnest laminates on the car.

Design Constraints

Must not create snag points inside the cockpit. Must be removable without tools for access to the systems behind them. Must maintain the shielding requirement between the driver and the steering rack and other mechanical components.

Manufacturing Process

Layup on a milled tooling board mold or a 3D printed mold for smaller panels, trimmed and drilled to jigs.

Full Material List

CFRP, typically a thin 0-90 and +/-45 stack. CR22 sidepod schedule from the composites knowledge base: +/-45 Textreme (80 gsm), 0-90 Textreme (80 gsm), Innegra plain weave (200 gsm), 0-90 Textreme (80 gsm), +/-45 Textreme (80 gsm).
