Pros of using Fibreglass in the Automotive Industry

Fibreglass moulded parts for motorcycle

Fibreglass is a prominent material for building vehicles. It’s well-tested, durable and a popular option for race cars due to it’s unique combination of light weight and strength.

Fibreglass is also popular for kit cars and bespoke car adaptations as it can be moulded into complex designs.

Here are the Pro’s of Fibreglass

Strong and long-lasting:

  • Stronger than sheet metal.
  • High resistance to corrosion, it will not rust.
  • Fire-retardant resins can protect the vehicle against fire

Design Freedom:

  • There are very few restrictions with fibreglass moulding technology.
  • Capable of holding detailed designs while remaining structurally strong and durable.
  • Can combine multiple parts into just one.


  • Improved aesthetics.
  • Achieve a variety of finishes
  • Fibreglass has a high tech appearance.

Cost Effectiveness:

  • Stable prices
  • Lower costs for maintenance and warranty work.
  • A lighter product means lower shipping and storage costs.

Special Characteristics:

  • Fibreglass has the least expansion and contraction with heat, cold and/or stress compared to metal, plastic, and wood

Main Cons of Fibreglass

  1. Fibreglass cracks and breaks in an impact –  metals deform and absorb energy in a crash – so a fibreglass car body would still need an internal crash structure to protect the occupants, negating the advantage of being lightweight.
  2. Fibreglass is not as durable as metal.
  3. Can deform with heat.
