Question

You are a historian who is compiling information on the changing materials used in a product in one of the categories listed below. Choose a product that uses a variety of materials that have been discussed in this lesson (for example, a car or a tennis racket). Using online or library resources, research past materials used to create the product. Be sure to discuss the materials currently being used for the design and include information on the sustainability of these resources. Your research must also explain why the materials changes were made (for example, safety, cost, or weight). Keep track of your references so that you can document all of the resources used for your report.

Answer 1

The automotive industry has evolved from using materials like wood and steel to lighter options like aluminum and carbon fiber, striving for improved fuel efficiency and reduced environmental impact. Long-chained molecule materials and electrically conductive materials are also key in the pursuit of performance and sustainability in car manufacturing.

Step-by-step explanation:

Evolution of Materials Used in Automobile Manufacturing

The development of cars is a fascinating study in the application of different materials for design and efficiency, reflecting broader changes in technology and societal values, including sustainability. Initially, cars were built using materials like wood and steel, but there have been significant shifts towards lighter and more sustainable materials such as aluminum and carbon fiber to improve fuel efficiency and reduce emissions. Innovations in flexible but durable materials, many of which use long-chained molecules, have also led to the creation of high-performance plastics that replace heavier traditional materials. Similarly, the transition to electric vehicles has prompted a need for electrically conductive materials that are effective for battery technology, leading to the exploration of various metals and alloys. The automotive industry is continually seeking environmentally friendly alternatives to reduce the impact of manufacturing and operation on the planet.

Not only do material choices affect the car's performance and lifespan, but they also have implications for recycling and sustainability. As such, the industry is constantly balancing factors such as cost, weight, safety, and environmental concerns. The ongoing quest for sustainability spurs on the innovation of biodegradable materials and the implementation of recycling programs.
