Quick explanation
Classification of materials
- This point belongs to Materials and their applications, especially Materials and their applications.
- You need to be able to classification of materials.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Why it matters
This objective helps connect Materials and their applications to exam-style questions, flashcards, and revision notes for Materials and their applications.
Quick student answer
Which of the following is a characteristic of thermoplastics?
Direct answer
Thermoplastics are materials that become soft when heated and can be reshaped multiple times without significant degradation.
Key terms
- Thermoplastic: A type of plastic that becomes soft when heated and hardens upon cooling, allowing for reshaping.
- Composite: A material made from two or more different materials that, when combined, produce a material with enhanced properties.
Common trap
Confusing thermoplastics with thermosetting plastics: Remember that thermoplastics can be reshaped upon heating, while thermosetting plastics cannot be remolded after they have set.

- Students are expected to be able to name specific materials for a wide range of applications.
Materials and their applications
- They must also be able to provide detailed and justified explanations of why specific materials and combinations of materials are suitable for given applications, with reference to: • physical and mechanical properties (working characteristics) • product function • aesthetics • cost • manufacture and disposal.
Materials and their applications
- Understand the appropriate use of materials including polymers, composites, woods and metals based on their physical and working characteristics such as: • malleability • toughness • hardness • resistance to corrosion and degradation • thermal conductivity • electrical conductivity.
Materials and their applications
- Calculation of quantities of materials sizes and costs.
Materials and their applications
- Students should know and understand the classifications of the following materials and be able to name examples that belong to each category: • metals (ferrous, non-ferrous, alloys) • woods (hardwoods, softwoods, manufactured boards) • polymers (thermoplastics, thermoset polymers, elastomers) • papers and boards • composites • smart materials • modern materials.
