Lamborghini: the monocoque of the new V12

Lamborghini continues the preview of the new V12 Aventador, heir to the Murcielago is intended to debut at the Geneva Motor Show, unveiling the new carbon monocoque frame made of fiber-reinforced CFRP. The shell is subjected to a patented process of compression, which increases rigidity and allows you to work as a single component in the event of an accident.

The total weight of the structure is 147.5 kg and it is still aluminum frames which are anchored to the mechanical components. The entire chassis weighs 229.5 kg declares and provides torsional rigidity of 35,000 nautical miles per degree of twist when the Murcielago was no more than 20,000 with a tubular steel structure with carbon fiber parts.

For the work CFRP carbon fibers were used three different techniques, depending on the capabilities of individual elements. The Resin Transfer Moulding (RTM), further developed by the Lamborghini so much to take the name of RTM-Lambo, involves the use of resin and subsequent heating of the mold, with the use of special molds made of carbon fiber.

The prepreg system instead provides for the cooling of the resin-impregnated and then cured in an autoclave, resulting in a better finish. Braiding The system predicts the intertwining of the fibers for the creation of tubular elements and structural fibers arranged diagonally across multiple layers.

The shell also provides members with epoxy foam sound-absorbing function and vibration reduction, while the rolled aluminum inserts are integrated in the front and rear for connection of the subframe. Very strict quality controls, with tolerances of 0.1 mm means the checks that take place both on raw materials components products.
