Las chapas de madera en F1 actualmente tienen una función de control de altura. La FIA las comprueba después de la carrera para que tengan un espesor mínimo, si no serán descalificados. La tabla mide 10mm de espesor, y solo pueden perder 1mm al final de la carrera.
Por supuesto es obligatorio, ningún equipo pondría un trozo de madera en el suelo si le dejaran. En los 80-90 (Hasta la fin del meapilas que hablaba con Dios en el cockpit
) los suelos eran de titanio, que provocaban esas chispas tan brutales que hemos visto tantas veces en aquella época.
According to
Formula One regulations, a rectangular skid block must be fitted beneath the central plane of the car. This skid block may comprise up to three pieces but must:
- extend longitudinally from a point lying 330mm behind the front wheel centre line to the centre line of the rear wheels
- be made from a homogeneous material
- have a width of 300mm with a tolerance of +/- 2mm.
- have a thickness of 10mm with a tolerance of +/- 0.2mm.
- have a uniform thickness when new.
- be fixed symmetrically about the centre line of the car in such a way that no air may pass between it and the surface formed by the parts lying on the reference plane.
The block used to be made of a material called Jabroc. Jabroc is made of
beechwood and built in a
composite process.
Veneers are layered and a high strength resin is used in each layer. It is pressurized and pressed, and brought to a certain and very consistent material density. As a result, each Jabroc skid plank is all but identical in terms of wear rate and material density. This material is still used in other motorsports.
The plank does not in itself restrict airflow under the car. It is used as a
gauge which restricts the minimum ride height attainable by the car. The closer the car is to the ground, the more efficient the front
wing and rear
diffuser. The higher the down force levels, the faster a driver may corner. Cornering loads can push the car down much lower to the road, which can be dangerous and so the skid block was introduced to counteract this. The thickness of the plank is one of the
parc fermé tests. If it is found to be worn beyond the allowed limit, the car is disqualified.
