naval use of composites 9 3. future trends 3.1. recycling of frps although grp provides designers, engineers and producers a product with moderate quality and long life span, its poor recyclability of this thermoset plastic has been always a problematic area mainly due to its inherent heterogeneous structure 12 .
composites uk has launched its next sector showcase event, this time on the topic of fibre reinforced polymer composites in the marine industry. fibre-reinforced polymer composites frps have been used successfully in marine appli ions for several decades in areas such as radomes and mass structures, super yachts, work boats and leisure craft.
the early use of composites in maritime crafts was driven by the need for lightweight, strong, corrosion-resistant, and durable components on naval boats. early appli ions were designed to overcome corrosion problems experienced with steel, aluminum, and wood.

the recent appli ions of fibre-reinforced polymer composites to naval ships and submarines are reviewed. since the mid-1980s the use of composites has increased considerably as the military strive to reduce the acquisition and maintenance costs and improve the structural and operational performance of naval craft.
another reason for using composite was to reduce weight, particularly the topside weight of ships. the high acoustic transparency of composites also resulted in their use in rodomes on ships and sonar domes on submarines. 3.2 early naval application of frp composites: 1. mine sweeper 15.5 meter 2. landing craft 15.2 meter 3.
