What does fibre injection moulding involve?

• A. Glass fibers filled with polymer to increase fibre roving, which can then be electroplated like ABS and metals.
• B. Mixing fibers into ceramic slurry for injection.
• C. Using carbon fiber cloth rolled into composites.
• D. Metal fiber injection.

Answer: (A)

Fibre injection moulding is about reinforcing a polymer with fibres to make a stronger, stiffer plastic. In this process, short reinforcing fibres, typically glass fibers, are mixed into molten thermoplastic so the fibres are carried into the mould with the plastic. The result is a fibre-reinforced plastic that combines the toughness of the polymer with the strength of the fibres, improving properties like stiffness and dimensional stability compared with the unreinforced polymer. The mention of electroplating is a separate finishing step that can be applied to plastics after moulding, but it isn’t the core of the injection-moulding process itself. The other options describe different manufacturing routes (ceramic injection, carbon-fibre lay-up, or metal-fibre concepts) that don’t correspond to fibre injection moulding of polymers.
