An equipment case must have a strong shell with a low density. A trial material is made by embedding glass fibres in a polymer.
| Material | Strength in MPa |
|---|---|
| Polymer | 70 |
| Trial material | 1100 |
| Material | Density in g/cm³ |
|---|---|
| Glass fibres | 2.5 |
| Trial material | 1.8 |
Explain how the glass fibres and polymer form a composite and use the data to explain why the trial material is suitable for the equipment case.
