TriboLab HD
The TriboLab HD high-torque friction materials tester enables more precise and repeatable brake friction, wear, and particle emissions studies than previously possible in a laboratory setting.
This system features the most advanced technology and offers the widest range of test capabilities, the most control over test parameters and conditions, and the most force torque in a research testing system, as well as support for brake particle analysis. With the ability to simulate the SAE J2522 protocols and other standards in the lab, TriboLab HD provides the data needed to make critical decisions earlier in the brake material development process, bridging the gap between the drawing board and dynamometer testing of brake pad and rotor materials.
TriboLab HD uniquely enables engineers and manufacturers to reduce development time and comply with emerging standards and consumer demands, while reducing costs and staying ahead of their competitors.
Bridging the Gap Between Drawing Board and Dynamometer Testing
Traditionally, dynamometer testing is the only method used to evaluate novel brake pad formulations under simulated driving conditions before actual on-road vehicle testing.
TriboLab HD provides the notable advantage of comprehensive materials testing under the various driving conditions required for regulatory compliance or certification earlier in the development cycle. This allows researchers to fine-tune materials formulations to a greater extent before expensive dynamometer testing.
Dynamometer Testing:
- Adds considerable expense if brake material formulations cannot initially meet standards;
- Occurs at a later stage in the development cycle;
- Requires test runs to be completed over several days;
- Provides little insight into the mechanisms underlying test failures; and
- Limits the ability to fully study brake particle emissions.
TriboLab HD:
- Reduces material costs and shortens time-to-market;
- Tests critical components earlier in the development cycle;
- Simplifies test design, setup, and completion – can begin testing on day one;
- Enables easy monitoring and comparison of test runs; and
- Supports brake particle collection and analysis.
Accelerating the Development Cycle
As engine types evolve and environmental concerns become more critical, new brake materials must meet increasingly stringent performance, comfort, cost, and safety requirements. The standard development cycle for these materials may take up to five years to bring these materials to market.
Specifically designed to help increase agility and reduce development time, the TriboLab HD high-torque friction material tester allows more rapid development of new materials at the cutting edge of the industry. Developers can achieve superior results by concentrating on only the best formulations — an extreme advantage in such a competitive market.
TriboLab HD offers significant improvements over currently available in-lab testing:
- Measure COF accurately at high loads and speeds with up to 50 Nm torque;
- Reduce material testing costs with coupons;
- Simulate SAE J2522 test scenarios for all-purpose roads;
- Maintain temperature during fade testing with direct heating up to 550°C; and
- Integrate seamlessly with third-party particle analyzers.
Providing Exceptional Performance and Ease of Use
TriboLab HD makes it easy to get meaningful test results. Its combination of advanced hardware and intuitive software is designed specifically for automotive friction materials testing and includes:
- Heavy-duty motor to provide 8.5 MPa pressure, applied at 120 km/hr;
- High-precision, low-noise, all-in-one load/torque sensor;
- In-situ heating to maintain temperature in between snubs and externally heat the rotor;
- Robust hardware to withstand the harsh demands of friction material testing and simulate real-world conditions; and
- Pre-programmed and easily modified scripts expedite testing and analysis.

Enabling Particle Emissions Studies
The health and safety implications of airborne particles created by brake wear are gaining international attention. As regional environmental standards develop, brake component approval regulations and consumer expectations will become increasingly strict. Developers will need to change the physical properties of new formulations or modify existing formulations to reduce particle emissions.
The TriboLab HD particle collection chamber seamlessly integrates with third-party particle analyzers to make it easy for manufacturers to study the entire wear process.
Critical functions for precise and repeatable in-lab wear studies include:
- The collection of particles from conventional and newly developed materials;
- Reliable, representative, and repeatable sampling and characterization of brake wear particles;
- The measurement of particle mass, number, and concentration in variable, highly dynamic conditions; and
- Particle size measurement over a large size range (<10 nm – 10 µm).
TriboLab HD addresses these functions with:
- Easy integration of commercial particle analyzers;
- Optimum control of parameters and simulation of different driving conditions and regulatory standards;
- Simulation of abrasion processes leading to direct emissions of particulates with high accuracy/authenticity; and
- Easily cleanable surfaces to reduce contamination and increase the reliability of environmental particle screening.
To exhibit how TriboLab HD could be employed to study particle emissions, Bruker integrated a third party 3-filter impactor with vacuum pump to collect PM of 1, 2.5, and 10µm.
The filters were then analyzed externally using SEM to provide chemical composition of the particles collected.
The particle collection chamber can be easily cleaned to reduce cross-contamination between runs.
