Explain the advantages of using titanium in manufacturing.
Titanium is strong, lightweight, and highly resistant to corrosion. It is used in aerospace, medical implants, and sports equipment due to its durability and non-reactivity.
What is the purpose of coated metals in design and technology?
Coated metals are used to improve the material's properties, such as corrosion resistance, wear resistance, or aesthetic appearance. Common coatings include galvanising or powder coating.
How does a smart material differ from a traditional material?
A smart material can respond to changes in its environment, such as temperature, light, or pressure. It changes its properties in a controlled way, whereas traditional materials do not react to environmental factors.
Give an example of a composite material and explain its use.
A common composite material is reinforced concrete, which is made by embedding steel bars or mesh into concrete. It increases strength and prevents cracking, making it ideal for construction.
What are technical textiles, and where are they used?
Technical textiles are fabrics designed for specific functions, such as durability, resistance to heat, or water resistance. They are used in applications like medical textiles, military uniforms, and automotive seat covers.
Describe one advantage of using nanomaterials in manufacturing.
Nanomaterials can have enhanced properties, such as increased strength, conductivity, or resistance to wear, even though they are lighter or thinner than traditional materials. This makes them ideal for use in electronics, medical devices, and coatings.
How are metal foams made, and what is their primary advantage?
Metal foams are created by injecting gas into molten metal, causing it to form a foam-like structure with a network of pores. Their primary advantage is their light weight while still maintaining strength, which is useful in aerospace and automotive industries.
What is a characteristic of thermochromic smart materials?
Thermochromic materials change colour in response to temperature changes. These are used in applications such as temperature-sensitive packaging or clothing that changes colour in heat.
How do Liquid Crystal Displays (LCDs) work?
LCDs work by using liquid crystals that align in different ways when exposed to electric fields, controlling the passage of light. This allows for the creation of images and text on screens, such as in televisions, monitors, and smartphones.
Why are composite materials often used in the aerospace industry?
Composite materials, such as carbon fibre, are used in aerospace because they are lightweight, strong, and resistant to corrosion, which improves fuel efficiency and the overall performance of aircraft.
