Brake pad material

[f1.redbaron]

Hello all,

I'm working on a project that revolves around the design of the brakes. I'm looking to do an analysis in ANSYS but I'm stuck on material properties. Basically, I don't know what material to research. I know that, for the most part, breaks are semi-metallic, but that doesn't really mean anything ti me because I need to be able to import the material properties in ANSYS. Does anybody have any idea where can I find the properties, i.e. what kind of steel is used and what are the material properties (I know that this is a trade secret, but a basic idea would be helpful).

Thanks

not sure if it´s helpful, but perhaps a start:

The typical composition of a Volvo 850 brake pad material was given as follows:
Function Material Amount (wt%) Comments
Matrix binder material 8
other 11
Fillers clay and iron oxide 8
Fibers steel, aramid, glass 30
Friction modifiers brass/bronze 15
graphite 15
metal sulphides 8
Abrasives quartz 5

Just to be sure, what do you want to research?
Brake pad material for general automotive applications or specificly for Formula 1?

Thanks for the reply.

This particular project is for an standard automotive brake. The problem that I'm having is trying to do ANSYS analysis on brake pad because in order for me to obtain meaningful results, I'd have to use proper material. Unfortunately, I haven't been able to find it in ANSYS material properties table. That is why I asked.

I saw that in some of the links you have provided, there is a composition by volume so that is extremely helpful. I will go through them in detail...thanks for the help!

you are welcome - hope it works out for you,
good luck with your project

Do you need anything more than a temp vs CoF curve?
