Why GRP?

The MAIN characteristics of thermosets (literally 'setting under heat') is that they require curing, when they undergo a molecular cross-linking process which is irreversible and renders them infusible. They thus offer high thermal stability, plus good rigidity and hardness and resistance to creep. It also means that, once cured, the resin and its laminate cannot be reprocessed, except by methods of chemical break-down, which are currently under active development. For practical purposes, therefore, cured thermosetting resins can be recycled most effectively if ground to fine particles, when they can be incorporated into new laminates, as cost-effective fillers.

Thermosetting resins have little use as pure resin, but require addition of other chemicals to render them processable. For reinforced plastics, the compounds usually comprise a resin system (with curing agents, hardeners, inhibitors, plasticisers) and fillers and or reinforcement. The resin system provides the 'binder', to a large extent dictating the cost, dimensional stability, heat, chemical resistance and basic flammability. The reinforcement can influence these (particularly heat-and dimensional-stability), but the man effect is on tensile strength and toughness. High-performance fibres, of course, have a fundamental influence on cost.

Special fillers and additives can influence mechanical properties, especially for improvement in dimensional stability, but they are mainly used to confer specific properties, such as flame retardancy, UV stability or electrical conductivity.

Thermosetting resins are normally used in the liquid state and solidify and harden on curing. With some resins it is possible to part-cure and then hold the resin in what is termed the B-stage, for the cure to be completed at later time.

Fiber Glass Commercial Vessel

NOV Fiberglass Systems glass reinforced epoxy piping is chosen for all commercial vessels including specialized vessels, oil tankers, gas carriers, car carriers, bulk carriers, and container vessels. The latest series of large container carriers are all fitted with Bondstrand™ Series 2000M piping.


Over 900 meters of pipes of sizes from 1.5" to 20" are installed on these 18,000 TEUs Container vessels. The Triple E Vessels: Economies of Scale, Energy Efficient and Environmental Efficient, benefit from weight savings of over 54 tons (vs Schedule 40 Carbon Steel Pipe), the light weight translates into fuel economy advantage or higher load capacity.
