What makes fibreglass both strong and flexible?

Glass fibres are strong but brittle, polymer is ductile.

Start playing free

  1. Glass melts into the polymer
  2. The polymer is stronger than the glass
  3. Glass fibres are strong but brittle, polymer is ductile ✔

Why: Strong, stiff but brittle glass fibres combine with a ductile polymer to give balanced properties.

Huh, didn't know that: Strong, stiff but brittle glass fibres combine with a ductile polymer to give balanced properties.
