Long Glass Fibre

Long Glass Fibre Thermoplastic (LGFC) materials are typically used where high strength is required in combination with toughness and impact performance.

Long Glass Fibre Thermoplastic (LGFC) materials are constructed from a thermoplastic resin base in combination with a long glass fibre reinforcement. The Glass fibre reinforcement type can vary from a continuous random matrix to unidirectional and woven glass mat arrangements. Combinations of reinforcements can be used within the same mould to tailor the design to suit the localised needs of the part.

Polypropylene is most the common resin base for the LGFC, but others, such as PET or PBT can be used to impart various properties to the part. We can help you select the most advantageous thermoplastic for your application.

Long Glass Fibre Thermoplastic (LGFC) composites are compression moulded by CME in cycle time’s equivalent to or less than those for equivalent injection moulded parts.

The mechanical properties of LGFC are typically much higher than those of injection moulded glass reinforced materials. This is because of the long glass fibre length achievable in a compression moulding process.

LGFC technology is commonly used where a lightweight alternative to steel is required. LGFC components are typically 30% lighter than steel equivalents.

Typical applications

  • Automotive applications – underbody panels, structural panels, seating structures, instrument panel structures, spare wheel wells
  • Logistics – shipping pallets, tote boxes
  • Civil Products – drainage pits and trenches, concrete slab forms, enclosures
  • Miscellaneous – structural bases, sporting goods, signage
