The building blocks of FRP construction are thermosetting and thermoplastic resins, fibre reinforcements (most often glass), and frequently structural core materials.
Two Families of Resin
Thermoplastic Resins
Materials such as ABS, polyethylene, polystyrene, and polycarbonate. Characterised by their capability to be melted and formed, then reheated once again to the plastic state.
Thermoset Resins
Most commonly employed in architectural FRP products. Convert from liquid to solid through polymerisation and crosslinking. Once cured with a catalyst, they cannot be converted back. Unlike thermoplastics, thermoset resins do not melt.
Among the thermosetting resins used for large building components, polyester resin is by far the dominant material. Vinyl ester resins are similar but feature enhanced corrosion resistance and toughness. Epoxy resins are used where superior chemical resistance is required. Phenolic and modified acrylic resins are employed for superior fire retardancy and low smoke generation.
