Expert Lecture Spotlight | Prof. Klaus Friedrich
Advances in the Tribology of Polymer Composites
Polymers and polymer composites have become essential materials in countless friction and wear applications. Yet, innovation in this space continues—pushing performance boundaries and expanding use cases under increasingly extreme operating conditions.
In this lecture, Prof. Klaus Friedrich explores the design of polymer composites engineered for low friction and minimal wear. A key focus is on the strategic use of advanced fillers, including:
Spherical nanoparticles
Classical tribo-fillers like carbon fibers, graphite flakes, and PTFE
The talk delves into how synergistic effects between nano- and micro-fillers can significantly improve the tribological performance of both thermoplastics and thermosets—especially when sliding against metallic counterparts.
Real-world applications include:
- Polymer-metal bushings in diesel fuel injection systems
- Electrically conductive, multifunctional polymer bearings
- Epoxy composites with microcapsules for self-lubrication and self-healing
- Additive manufacturing of tribological components
- High-temperature coatings for engine pistons, bushings, and anti-sticking molds
A compelling blend of fundamental insights and industrial relevance, this talk highlights the future of smart tribo-materials in demanding environments.
