Trend strength (stronger than spider yarn) and high conductivity. These nano-objects are the basis for nanocomposite parts for the automotive sector. Several car manufacturers or their suppliers have been testing these new materials for automotive applications. More information Yole Développement is a market research and strategy consulting company which specializes in micro- and nanotechnologies. Part of the information presented in this article was extracted from the NanoSEE (Nanomaterials Industry Status and Expected Evolution) report, published by Yole Développement in 2006. Fig. 1: Nano-objects : nanoparticles and carbon nanotubes. Examples of nanoclay and nanotube nanocomposites for automotive Nanoclays are the nano-objects most widely used in automotive parts. Natural nanoclays are nanosized, platelet-shaped particles agglomerated together. Depending on the dispersion of nanoclays in the polymer matrix, their effects are different. To get an exfoliated nanocomposite (i.e. where nanoclay platelets are separated from each other and dispersed throughout the whole polymer matrix), functionalization of the nanoclays is required. General Motors showed the first commercial use of nanoclays in cars in 2002, with the Chevrolet Astro and GMC Safari vans. The step-assist was made of thermoplastic olefin filled with 3% nanoclays. It was much lighter, stiffer, and less brittle at cold temperatures than those made with the conventional talc filler. Although this application drew large media coverage, it has since been terminated. In 2004-2005, GM released the Chevrolet Impala with a body side trim made of nanoclays. A weight savings of 3 to 25% was achieved on the redesigned parts, but their performance is questioned. In 2005, GM’s Hummer H2 SUT cargo bed trim contained 3 kg of nanoclays per car. Other car manufacturers commercialising nanoclay-filled parts include Maserati, Daimler Chrysler and Audi. Maserati engine bay covers are made of Ube nylon-6 nanocomposites, containing 2% nanoclays by weight. The results are reduced weight, increased mechanical performance, and an improved surface appearance (versus glass-reinforced nylon). Daimler Chrysler made the inner door handle of the Smart Forfour in Polykemi AB‘s polypropylene with nanofillers and conventional fillers. Audi and Putsch GmbH developed the heater vent of the A3 in PP/PS, filled with nanoclays to replace painted ABS. Nanoclays help to compatibilize 60-80% PP with 20-40% PS. The results are improved scratch resistance and a luxurious surface feel. In automotive applications, carbon nanotubes are also eliciting strong interest as a mechanical reinforcement, or for their conductive properties. Renault used to reinforce PP/PPE alloys with nanotubes for Scenic fenders. Carbon nanotubes replaced carbon black in fenders for electrostatic painting. However, this has recently been halted for cost reasons. Fuel-delivery lines are also an application for carbon-nanotube nanocomposites. Similarly to nanoclays, functionalization of the nanotubes is also required to obtain a good dispersion and distribution of the filler into the matrix. This competence in functionalization and compatibilization with the matrix is a very specific skill mastered by only a few players. Outlook Today, only a limited number of nanotech products are integrated into automotive applications. North America was the starting point of this business. The performance-to-cost ratio is a major hurdle for broader market acceptance, since nano-objects are still expensive and their added value is not always sufficient to balance their cost. The evolution of these fillers is linked to nano-object prices, which will certainly decrease as production capabilities develop. Generally speaking, nanofiller prices are much higher than those of standard fillers. This increase in rawmaterial costs can be balanced by a reduction of the filler content and the reduced final weight of parts, combined with improved properties. Thus, the addition of nanofillers often requires rethinking the part (design changes) and the processing technologies (new moulds, modified rheological behaviour, etc.), which also needs to be considered in the part’s cost calculations. Nanocomposites are developing in the automotive market, but proof of the competitive advantage of nano-objects remains to be confirmed, taking into account cost and performance. Significant further development and modification of current processing may yet be required (rethinking of the global system, including part design). Moreover, nanotoxicity and recycling are important subjects that must be taken into account while using these new materials.
