[姑且一看]刹车片摩擦系数

radonradon

好像就这家列出了刹车片的摩擦系数https://directautospares.com.au/

对于喜欢物理的我就是喜欢这样的讨论，

对于喜欢辩论的我就是喜欢提不同的意见，

这摩擦系数估计也仅仅是参考，

和不同的地方发生摩擦，系数或许也不一样，

所以想知道这个系数的参照物，

估计是刹车盘，某种

The National Bureau of Standards (NBS) started testing of brake material in the US in 1920. The testing setup was then shared with manufacturers who wanted them so that they could begin to test their own products.[16] Over time the NBS continued to develop new instruments and procedures for testing pads and lining, and these standards eventually became the standards for the American Engineering Standards Committee's Safety Code for Brakes and Brake Testing.[16]

SAE J661 testing is used to determine the friction of different brake pad materials by testing a 1 inch (25 mm) square liner with a brake drum. This testing yields values both a hot and cold coefficient of friction, which is then paired with a letter designation.[8] The table below outlines what letter goes with each range for the coefficient of friction. An example of the designation would be "GD", where "G" is the normal coefficient, while the "D" represents heated.[8]

Letter Designation for Friction Coefficients
C        <0.15
D        0.15 to 0.25
E        0.25 to 0.35
F        0.35 to 0.45
G        0.45 to 0.55
H        >0.50
Z        unclassified

没屁用，我只关心一副刹车能用多久
