Friction + or - due applied

04/15/2007 1:05 PM

I am looking for a constant for an increase or decrease in friction due an increase in heat.

Applied heat to surface A and surface B with both surfaces in contact with N force applied surface A directed up to surface B and W force applied surface B directed down onto surface A.

It will depend on the surface material and temperature range. For example the tires we are currently using in a race circuit I am involved in reach their maximum grip (friction) at around 260° F while the tires we were using a couple of years ago peaked at around 230° F.

Dears, It is obvious in fluid medias. The resistence is directly proportional to the density which is inversly proportional to the temperature of the media.
