High-tech materials discusses carbon fiber, graphene, and magnesium alloys. Carbon fiber is strong, light, and resistant to heat and chemicals. It is made from polymers through carbonization and is used in vehicles, aircraft, and sports equipment to reduce weight. Graphene is the thinnest known material, with unprecedented strength and conductivity. It is being researched for applications in electronics, filtration, and composites. Magnesium alloys have high strength to weight ratios and are used in cameras, cars, sports gear, and aircraft to lower component weights. The document concludes that advanced materials have driven major technological advances and can be recycled to reduce resource usage.
