High coefficient of friction material
High coefficient of friction material
(OP)
Looking for a material that has a high coefficient of friction ( >.5) and is capable of withstanding very infrequent high energy stops (3ms duration with 1000W/in^2 energy at surface every 2 seconds). Temperature of rotor rises to about 100F from room temp under heavy use.
Currently, we are running vs. a low carbon steel rotor (this could be changed as well) with a number of different rubber compounds. The rubber friction is not staying stable and I'm looking for a new class of material to try. Any ideas?

RE: High coefficient of friction material
There are a lot of racing fans looking at this site maybe one will jump in.
What configuration is your braking system?
Here is list of some of the available brake pad materials.

Also check the NASA site as the have done considerable work on brake materials.
Here is the website for high performance brakes

You might consider larger pads and/or more rotors to try and drop the temperature, although the claim for racing brakes is COF goes up as temperature increases.

What are the overall dimension of your disc, diameter (inner outer diameter) and thickness, is vented o solid?
What type of assembly is used to fit the disc to the shaft?
You use a mechanical or hidraulic caliper?
If is hydraulic what are the maximum pressure in the system?
If is mechanical what is the maximum lenght that you are able to use in the arm load?
What is the max. shaft speed?
Do you know what desceleration you want to hold during the stops?
Variation in torque will be an issue for your application?
Do you know the maximum torque the machine is able to generate?
With this information I will be able to understand better your problem and recomend something to you.
