Automotive Shielding (Heat & EMI): Technology Innovation, Key Companies & Market Research

Note: The free primer on Automotive Shielding can be requested from here.

Automotive shielding is the need of the hour as it aids in preventing the transfer of heat in-vehicle components. Automotive heat shields are used to provide protection to the vehicle body against excessive heat generated by the engine and exhaust systems. 

EU set 2020 as the year to limit the average CO2 emission per kilometer per new car sale. Additionally, Germany has inclined the EV subsidies while Italy raised incentives from €60 million in 2019 and €70 million in 2020. The ascending demand for fuel-efficiency standards will drive the market for Automotive Shielding. In 2020, The U.S. auto industry sold approximately 3.4 million cars.

APAC Region will see soaring market growth in the Global Automotive Market due to the accelerated development of intelligent transport systems. The other factor is an exponential increase in connecting mobility in countries such as China and Japan. 

Customers have become more conscious and are opting profoundly the vehicle that has automotive shielding. The materials that are used in automotive heat shield fabrication comprise aluminum, nylon, and ceramic.

It is observed that sometimes these exhaust gases reach temperatures up to 900 degrees. The high temperature can cause extensive damage to the vehicle if shielding is not provided. Automotive shielding has become a necessity to make the vehicle function more effectively. 

To understand the industry challenges relating to the automotive shielding industry, we went through thousands of scientific pieces of literature/ academic publications and patent literature based upon which our team found the following major industrial problem: 

  1. Thermal damage due to low heat dissipation in the engine room.
  2. Sound absorption performance has not been satisfactory by the conventional panel.

Post comprehensive analysis we came across the following viable, innovative, and possibly the finest solutions:

  1. Fibers having different thermal expansion coefficients are arranged in a radial shape. When the temperature becomes higher, the bonding fiber material is deformed. And the plurality of air holes are formed in the fiber layer. Therefore, heat dissipation is promoted through the vent holes, which helps in avoiding heat retention.
  2. The composite panel is used for sound absorption and sound insulation. The composite panel has a perforated panel and an embossed panel. A sound-absorbing and insulating material are inserted between the first perforated panel and the embossed panel. Therefore, perforated holes diversify the frequencies of sound.

The difference in vision about the future can make all the changes. It is always good to stay ahead and have a very clear vision about future technology. The future ofthe automotive shielding industry willfocuson customer convenience, compliance, and guidelinesIt has a very promising future.

Game-Changing Technologies in Automotive Shielding Industry

  1.  Honda Motor – A plurality of bonded fibers obtained by bonding a first fiber and a second fiber having different thermal expansion coefficients from each other are arranged in a radial shape. When the temperature becomes higher, the amount of thermal expansion is different between the first fiber and the second fiber, and the bonding fiber material is deformed, for example, in a curved manner. As a result of making the fiber layer lose, a plurality of air holes are formed in the fiber layer. At high temperatures, heat dissipation is promoted through the vent holes, so so-called heat retention can be avoided, and thermal damage can be effectively prevented.
  2. Hantec Technology – The composite panel may include a first perforated panel and a second embossed panel. A sound-absorbing and insulating material inserted between the first perforated panel and the embossed panel. First perforation groups are formed by collecting a plurality of first perforated holes. Second, embosses are formed by forming the plurality of cells and coupled to the first perforated panel. Perforated holes may be irregular. As a result, the sound absorption performance may be improved by diversifying the frequencies of sound.

 Inspiring Industry Cases of Automotive Shielding Industry

  1. Nissan (JAPAN) – Nissan will demonstrate the new lightweight sound insulation material, known as acoustic meta-material. A combination of a lattice structure and plastic film controls air vibrations to limit the transmission of wide frequency band noise, such as road and engine noise. Weighing one-fourth of conventional sound insulation materials, Nissan’s acoustic meta-material delivers both quietness and efficiency.
  2. NationalUniversityofSingapore (SINGAPORE) -For the first time, recycled car tire fibers (RCTF) shredded from car tire waste are developed successfully into a novel material, a rubber aerogel, using polyvinyl alcohol (PVA) and glutaraldehyde (GA) as crosslinkers through a cost-effective freeze-drying method. The rubber aerogel exhibits excellent heat insulation properties, very good thermal stability up to 500 °C.
  3. Nanoprom (ITALY) – An innovative paint is revolutionizing the world of aeronautics, automotive (especially electric cars), and Formula 1 itself. Thermal Shield is based on silicon and does not contain carbon atoms, on the other hand, makes the performance of this paint exceptional against fire and heat sources. This flame retardant paint, applicable to engines and potentially flammable components.
  4. Technical University of Cluj-Napoca (ROMANIA) – Sheep wool is a sustainable material for acoustic applications. The materials were made from sheep wool by thermo fusion with polyester fibers obtained from recycled polyethylene terephthalate (PET). It was demonstrated that sheep wool with PET fiber was a good sound-absorbing material at medium and high frequencies.
