Question

Assume you are making a compisite material airplane, which has ligter weight and more fuel effciency. Describe how your airplane will put pressure on a culture outside of America (Choose a specific country). How your airplane will affect their society, culture, economic, and envornment, etc?  

Answer 1

Composite materials is used because:-

To improve environmental performance and cost efficiency, the transport industry is moving away from materials based on metal and towards lightweight composites, such as reinforced polymers. Less weight results in lower fuel consumption – and greenhouse gas emissions.

Carbon-fibre-reinforced polymers are now the preferred composite materials as they provide low weight and high strength with cost savings – a particularly attractive combination for the airline industry.

The key problem is that carbon fibre cannot simply be melted down and reformed like aluminium. Carbon fibre composites get their strength from long, precisely aligned carbon fibres, fixed within a glue-like polymer that is cured at high temperatures and pressures. Once cured, most of these tough polymers will not melt and have to be burned off or chemically dissolved to reclaim the valuable fibres.

First, the total global warming impact of each flight is thought to be around twice as high as the CO2 emissions alone (see 'What's an aviation multiplier?', below). Second, the figures are skewed in favour of British travellers. The standard way to account for the emissions for an international flight is to allocate half to the country of departure and half to the country of arrival. But UK residents take up two-thirds of the seats on the average plane landing at or taking off from a British airport. This means the official statistics are effectively offloading the emissions of British holidaymakers and businesspeople on to the countries they're visiting. Third, the aviation industry causes emissions over and above those of the planes themselves. The processing and transportation of the aviation fuel, and the manufacture and maintenance of planes, airports and support vehicles all create extra carbon dioxide.
