The Applications and New Areas for Ceramics in the Automotive Industry

The use of technical and thermal ceramic materials has expanded within the automotive industry. The physical, chemical and performance properties specific to these modern ceramics is creating an increasing number of applications.

Piezoceramic transducer-based ultrasonic parking and level sensors have been in use for the past two decades, while ceramic brake discs are widely used at the luxury end of the market.

The latest generation of ceramic materials are ideally suited to meet the new challenges posed by the introduction of hybrid vehicles and innovations in manufacturing methods. Furthermore, some form of thermal ceramic material comes into contact with virtually all components found on modern vehicles during manufacturing.

This article discusses some of the automotive applications where ceramic materials are becoming increasingly attractive.

Advanced Hybrid Vehicles

The recent advancements in battery technology are placing new demands on thermal management systems. Precision engineered ceramic shafts and bearings supplied by Morgan Technical Ceramics are used in the water cooling pumps of next generation hybrid vehicles for cooling critical engine electronics and lithium-ion batteries.

In addition to their longevity due to their excellent chemical resistance to the glycol coolant, ceramic products are lightweight which contributes to improved fuel efficiency and low noise running.

Windscreen Manufacture

Modern windscreens are produced by heating up flat glass panels, followed by pressing or bending them into shape. Considering the high value and tight production deadlines of windscreens, it is crucial to eliminate the possibility of breakage during the forming process.

This risk can be avoided by placing papers made of low biopersistence high temperature fibers on either side of the glass. This method means the windscreen can be protected from physical damage induced by the extreme heat involved in the forming process without affecting the heat transfer required for the bending process.

Exhaust Manifolds

Protecting the electronic engine management system of a vehicle from high temperatures surrounding the engine is a major challenge for design engineers. The use of a variety of heat shield systems can handle the extreme heat from the exhaust manifold. There are many different metal encased insulation options available, including heat resistant blankets, thin papers and felts. Besides providing heat protection, these systems can also mitigate engine noise.

Diesel Particulate Filters

The segments of a diesel particulate filter (DPF) are bonded together using a ceramic paste composed of specially engineered low biopersistent fibers. The application properties of the paste are controlled by these fibers during production. In addition, these fibers deliver the thermal shock performance essential for the high temperature regeneration cycle used for filter cleaning during driving the vehicle.
