Application of Infrared Spectroscopic and Gas Chromatographic Techniques to Brake Lining Development

Infrared and gas chromatographic techniques are capable of yielding compositional data on the organic constituents of brake linings. Examples will be given relating such compositional data to the state of cure of the resin binder, to the presence or absence of specific organic friction modifiers, and to determining whether or not the proper resin binder system was used.

The success of the above techniques in the solution of specific brake lining problems does not necessarily recommend them as quality control tools.
