In the context of the given options, the composite material is Carbonfibre reinforced plastic (CRP).
Here's why:
1. **Composite Material Definition**: Composite materials are made up of two or more constituent materials with significantly different physical or chemical properties. In this case, Carbonfibre reinforced plastic (CRP) consists of carbon fibers embedded in a plastic resin matrix.
2. **Carbonfibre reinforced plastic (CRP) Example**: CRP is a type of composite material widely used in various industries due to its high strength-to-weight ratio, stiffness, and durability. It is commonly used in aerospace, automotive, and sports equipment manufacturing.
3. **Other Options**:
- **Graphene**: Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice. It is not a composite material but a pure form of carbon.
- **High impact polystyrene (HIPS)**: HIPS is a type of plastic that is not a composite material. It is known for its impact resistance and is often used in packaging and consumer goods.
- **Titanium**: Titanium is a metal known for its high strength, low density, and corrosion resistance. It is not a composite material but a pure metal.
By understanding the definition of composite materials and applying it to the given options, we can identify Carbonfibre reinforced plastic (CRP) as the composite material in this scenario.
