The Brake Abrasion Properties in Two Kinds of Platelet Titanate Compound Formulations, and the Swift Brake Property Evaluation by Using the Thrust Test Method 2007-01-3950

There are various requirements, such as NVH performance, wear resistance, stability in friction level, rotor compatibility, etc. for brake pad of friction materials. In our previous report, we reported that platelet titanium compounds stabilize the friction value and change the effectiveness depending on the difference in the chemical formulation.
In this report, we synthesized two kinds of platelet titanate compounds and made the brake pads mixed with both materials in a particular ratio. The brake effectiveness performance tests and the wear performance tests have been conducted in accordance with JASO C-406 and JASO C-427.
As a result, when two kinds of titanate compounds with different rotor attacks were mixed, they indicated the wear characteristics that wouldn't result in separate respective use; only when mixed together.
Presently, the inertia dynamometer is generally used, based on the JASO, when evaluating a brake property, but it takes too long to retrieve data for one sample. We tried, instead, using the thrust wear test machine that can get the data for the effectiveness and wear performance tests for brake pads in a short time and operates easily. The results showed the data between JASO C-427 and the new swift thrust test to be very similar in nature. We found that we can make use of this easier method for brake property evaluation.
