Fibre glass is a composite material of_________________?
Correct answer: C. Glass fibre in a polymer matrix
- A. Polymer fibre in a glassy matrix
- B. Glass fibre in a metallic matrix
- C. Glass fibre in a polymer matrix
- D. Both 'b' & 'c'
Explanation
Fibreglass consists of strong glass fibres embedded in a polymer resin matrix, which binds the fibres and transfers stress. A metallic matrix would describe a metal-matrix composite, not ordinary fibreglass.
