Automotive materials

Surface finish of parts is another important source of economic advantage. Surface roughness depends on the orientation of glass fiber. The process was optimized using data from surface smoothness measurements. A conductive RIM was developed to produce material ready for electrostatic painting without the need for further surface preparation. 

The choice of plastic material for automotive parts is influenced by its potential recyclability. One recent example shows that the use of recycled material gave the added benefit of an approximately 10% reduction in weight. This involved the use of recycled material in the Chrysler Neon rear spoiler. Major considerations in this respect are thermal and UV stabilities of the reprocessable material combined with low weight and mechanical protection performance characteristics.

Below are some commercial examples for automotive material applications  

A floor mat consisting of a PLA fiber was introduced in 2003 by Toyota in the Raum and Prius models. Here, PLA end groups were capped to prevent hydrolysis. 

Mazuda developed a new nucleating agent and a compatibilization agent using a derivative of PLA.

In ground transportation, the push for advanced-performance materials has been less dramatic because cost is the discriminator in the selection of components and systems. However, incremental improvement in automotive materials has been substantial in many areas, particularly in structural steels and plastics. 

In the past decades, polymer materials have been continuously replacing more traditional materials such as paper, metal, glass, stone, wood, natural fibres and natural rubber in the fields of clothing industry, E E components, automotive materials, aeronautics, leisure, food packaging, sports goods, etc. Without the existence of suitable polymer materials progress in many of these areas would have been limited. Polymer materials are appreciated for their chemical, physical and economical qualities including low production cost, safety aspects and low environmental impact (cf. life-cycle analysis). 

The chemical industry contacts supply chains, such as those for construction materials, automotive materials, and food, at multiple points. We can clean, disinfect, and genetically engineer seed. We can provide advanced coatings and packaging materials, as well as systems to detect bacterial contamination and spoilage. Can we make supply chains safer ...

Chemical substances are materials which can be produced or used in chemical processes. Chemical processes include such reactions as combustion. Since the rise of the modem chemical industry in the nineteenth century, numerous chemical substances have been developed and created including acids, bases, fertilizers, ceramics, catalysts, dyestuffs, fabrics, explosives, paints, plastics, petrochemicals, pharmaceuticals, agricultural chemicals, specialty chemicals, automotive materials, and home and commercial electronics components.

Fire test requirements for the acceptability of automotive interior materials should be changed so that materials with improved fire performance are used in future. Since the fire performance of typical car interior materials seems to be poorer than that of conventional plastic materials that can be found commercially in the market place, then improvements in automotive materials lire performance should be easily achievable. This can result fi om either using intrinsically safer plastic materials or from adding flame retardants to existing materials.

Automotive companies develop their own standards if proprietary technology is involved or when suitable standards (ASTM, SAE, NACE, etc.) do not exist. These company standards become more valuable when they become the basis of a standards writing organization standard. Therefore, cooperative efforts to prepare automotive materials related standards at organizations such as ASTM, NACE, and SAE are extremely strong and active.

In the last few years, the question of the disposal and recycling of non-metallic automotive materials has assumed great importance. In essence, the problem centres on the fact that the plastics content of vehicles, hitherto discarded and expended as landfill, has Increased to the extent that it threatens the viability of the whole operation. Designing for recycling is now a very active field of study. In the short term, however, widespread concern about the possibility of new legislation is dampening the enthusiasm for plastic body panels (see Chapter 8).
