Aston Martin Crash Structure. The material has been in existence for more than fifty years but their use in the high volume car manufacture is still limited or low. Most of the car parts, including the crash beam, are made from steel; the material, steel, is the favourite choice in the majority of vehicle assembly applications (Li, Chen, and Sun, 2010). Nowadays polymers, for example thermoplastics are commonly utilised in the automotive parts since they avail high production rates through injection moulding. Thermoplastic materials are regularly utilised in the manufacture of high dimensional precision components (ACI, 2011).The structural long fibre reinforced thermoplastic structures are being used in the automotive industry, for example the glass-reinforced polypropylene, are replacing the existing casted aluminium frames.

The material can be bolted easily and is 27% lighter when compared to the aluminium. In addition, its manufacturing or production cycle time is about 4 minutes less than that of aluminium. The structural thermoplastic components are also known to provide enhanced or elevated levels of energy absorption (Eom, 2009).The Aston Martin uses carbon fibre monocoque that is bonded to the extruded aluminium substructure, with rear and front glass reinforced polyester crash structure elements (Materials Today, 2008). As seen in figure 2, the carbon fibre performs exemplary well.Plastics are utilised extensively in rear and front ends of cars, since they have high specific energy absorption. The plastics avail extensive freedom in terms of shaping while maintaining shape, dimensional stability, with the high function integration. Besides the high energy absorption and high stiffness-to-weight ratio, the thermoplastic foams have high noise absorption characteristics. The Aston Martin front crash beam is predominantly made of carbon fibre.The composites require specialists in the materials and process knowledge in terms of functional integration, orthotropic behaviour, light-weighting, and the styling freedom.
