Wear resistance of underfloor skid planks was insufficient
Solution
Development of skid planks to suit

 

Formula 1 underfloor skid plank

The question 
Within DRIE-D the idea originated that with the new, ultra wear-resistant D-glide FC material, it should be possible to make more wear resistant skid planks for Formula 1 racing cars than with the previously used materials. There was no customer question, so after DRIE-D approached McLaren with the idea to use D-glide FC as plank material, McLaren immediately was interested.

The situation
For aerodynamic reasons the Formula 1 racing teams want to have as little distance between the floor of the car and the circuit as possible. Underneath the cars a mandatory skid plank is used. These planks have a strict 1 millimetre wear allowance. This prevent the teams from setting up their cars too low to the tarmac, which can lead to dangerous behaviour in corners and around curb stones, behaviour that may have played a role in some fatal accidents.

The practice
Up to 2002 McLaren produced their own dedicated composite material for this application. Other teams used simpler materials such as laminated wooden planks.

The solution
Wear planks produced by DRIE-D. Up to 2002 McLaren produced their own dedicated composite material for this application.

The result
Because D-glide FC is much more wear resistant than the dedicated McLaren plank material, the cars could now be set up lower to the tarmac. The ‘plank’ touched the circuit more often but thanks to the excellent wear resistance of D-glide FC, the total wear during a race remained under the 1 millimetre limit. Because a lower set up car is faster, the McLaren cars became even more competitive.
