+++ PRESSRELEASE +++ 09/14/2020 +++ LIQFRIC® CHIP-IN-PAD Projekt

First vehicle equipped with LIQFRIC® chip-in-pad concept.

LF GmbH & Co. KG with its brand LIQFRIC® has invited guests to a first meeting at the airport of Griesheim to present the results of their joint research work with Fraunhofer LBF on August 27th, 2020.

“We are proud to announce that we were able to invite a very limited number of guests to present the results of our piezo-sensor integration into our liquid friction materials during the molding process. We were able to test the cured and sensorized pads on a test dyno which was provided by Tribotecc GmbH. The data collected during a typical sequence of the AK-Master test series allowed our partner Fraunhofer LBF to analyze the performance of the sensors during brake actuation. These results and further details were presented to the audience during our meeting”, said Roman Milczarek, Director of R&D.

To complete the sensor experience, a vehicle provided by a well-known premium OEM was equipped with sensor pads on the front axle of the vehicle and hard wired into the back of the car to a multichannel reader/display system. Via this set-up, the participants of the presentation were allowed to see, probably for the first time, the real pressure conditions applied to a friction material during braking on the air field’s landing strip.

As one visitor said, the content and the combination of the results presentation, followed by an open discussion on the future potentials of this technology and the final real performance on a serial vehicle made the difference to most of the technical discussions he was part of before.

The ultimate goal of the company is to prepare the friction pad to become a player in the IoT in the future. The initial task may be to provide insights into the current operational work of friction brakes via calibrated measuring friction pads and allow for better understanding of braking activities while ultimately providing piezo-sensor pads for serial automotive applications.

“All of the above would not have been possible without the generous support and involvement we received. Therefore, I would like to thank:

• Mittelstand 4.0 Kompetenzzentrum Darmstadt der IHK Darmstadt sponsored by BMWI for the grant provided for the project,
• Fraunhofer LBF Darmstadt for the project support during the whole project phase,
• Tribotecc GmbH for providing valuable testing time on their dyno-equipment,
• BMW AG for providing the vehicle testing platform prior and during presentation,
• CriBaTec GmbH for conducting the driving and braking experience,
• Mr. V. Peddoju for conducting all the measurements and data assembly during his master's thesis,
• FZD TU Darmstadt for discussions about joining the sensor pad project and providing the location for the meeting”,

added Roman Milczarek proudly.

LF GmbH & Co. KG was founded in Leverkusen in March 2016 and follows the strategic idea of producing friction materials based on a liquid friction compound that can be hardened at room temperature to make high-temperature stable friction lining materials for automotive, rail, and clutch- as well as industrial applications.

The company has entered development projects and collaborations with some key players in the brake- and clutch industry in Europe and especially in Germany.
