陶瓷、聚合物与复合材料
Ceramics, Polymers & Composites
描述陶瓷（坚硬、易碎、耐热）、聚合物（柔韧、轻质、性能多样）和复合材料（结合组成材料的性能）的性质和用途，并给出每种材料的实际例子。
Describe the properties and uses of ceramics (hard, brittle, heat-resistant), polymers (flexible, lightweight, variable), and composites (combine properties of constituent materials), giving real-world examples of each
学习证据 / Evidence
- 能给出陶瓷、聚合物和复合材料的关键性质，并分别举例说明。
- 能解释在特定应用中为何使用复合材料而不是单一材料（例如自行车中的碳纤维增强塑料）。
- 能识别天然聚合物和合成聚合物。
- 能解释为何聚合物的性能可以在制造过程中进行调控。
- Gives the key properties of ceramics, polymers, and composites with examples of each
- Explains why a composite material is used rather than a single material in a given application (e.g. carbon-fibre reinforced plastic in bikes)
- Identifies natural and synthetic polymers
- Explains why polymer properties can be tailored during manufacturing
评估问题 / Assessment
如果{{name}}正在看一辆由碳纤维制成的赛车，他们能解释为什么单独使用碳或塑料效果都不够好，以及这种组合形成的复合材料为何比其中任何一种材料单独使用都更好吗？
If {{name}} was looking at a racing bicycle made of carbon fibre, could they explain why neither carbon nor plastic alone would work as well — and what makes the combination a composite better than either material on its own?
