Carbon-fibre-reinforced thermoplastic polyester air extractor bonded in one piece

Sabic Innovative Plastics : 21 November, 2012  (Application Story)
The Camaro ZL1 air extractor is engineered from carbon-fibre composites to achieve the highest stiffness and strength achievable with the lowest mass.

The air extractor on the General Motors 2012 Chevrolet Camaro ZL1 sports car makes extensive use of adhesive bonding to join two components to the one-piece design. Those two components are a polyamide vent screen and the water deflector moulded from a member of Sabic’s high-performance Valox resin family, which are based on polybutylene terephthalate (PBT) and/or polyethylene terephthalate (PET) polymers. The adhesive bonding also isolates the carbon composite panel from the rest of the aluminium bonnet, preventing galvanic corrosion.

This carbon fibre prepreg composite part pulls air through the lower grille and out through the hood, cooling the engine, increasing efficiency and reducing lift in the process.

Valox resin delivers the high heat performance required to ensure the long-term durability of the air extractor’s water deflector. This component, designed to deflect water from entering the engine compartment, must be able to withstand high temperatures coming from the engine. This is particularly critical given the deflector’s location on the under-side of the bonnet and close proximity to the engine. The Valox resin grade selected for this application meets the requirement, delivering up to 216C in heat resistance, while also offering an excellent balance of chemical resistance, dimensional stability and impact performance.

Another key benefit of Valox resin for this application is the material’s high quality feel and surface appearance, giving the deflector part a premium look and aesthetic attractiveness that consumers demand in a high-performance sports car. The part is also moulded-in colour, offering improved aesthetics while reducing costs and emissions associated with the painting process.

“The award winning air extractor, with integrated water deflector, allowed GM to achieve high performance and high temperature resistance, all with the desired styling, which is not possible with a one-piece carbon fibre solution due to design limitations,” said V. Umamaheswaran, Director of Marketing, Automotive, Innovative Plastics.
