Lamborghini Aventador: innovative monocoque

Debut at the Geneva Motor Show 2011 The new Lamborghini Aventador, the new heir to the V 12 Murcielago, Lamborghini meanwhile gives us some information in the preview, revealing the new monocoque carbon fiber reinforced CRFP obtained. The body has been subject of a new work performed in compression, this in order to obtain a higher stiffness in the event of an accident, this body weighs only 147.5 kg host the anchorages for the aluminum chassis and mechanical components.

The whole chassis weighs 229.5 kg with a torsional rigidity of 35,000 nautical miles, that of the Murcielago, steel tube as carbon fiber, did not exceed 20,000 NM. Three different techniques were used to work the carbon fiber of the new Lamborghini CRFP Aventador, or Resin Transfer Moulding (RTM) that uses a resin to the mold then heated using special molds for carbon fiber, this process has been perfected by Lamborghini so much to take the name of RTM-Lambo.

The other processing technique has been used instead Prepareg, a technique that involves cooling of the resin impregnated cured in an autoclave then, that to get a better finish. The third technique of working the body was instead Braiding, which provides for woven carbon fiber (and diagonally arranged on several layers) to create tubular elements.

The shell also has elements Lamborghini epoxy foam to reduce vibration and ensure sound-proofing, quality controls were very strict checking both raw materials and components of final products.
