GRP Stands for ‘Glassfibre Reinforced Plastics’, also referred to as ‘Fibreglass’, ‘Composite Plastics’, and in the USA, ‘FRP’. It is an amazingly versatile material, and one that is little understood in industry, but which has truly immense potential across a wide spectrum of applications.
Its vast range of properties can be confusing to the uninitiated. It is a ‘Plastic’ but it displays few of the disadvantages of conventional ‘thermoplastics’ in everyday use.
For instance, it will not melt, but will burn in a similar way to wood, but can be easily and cheaply made fire retardant. It is very strong - seven times the flexural strength of steel – yet very lightweight with the tremendous energy absorption properties which have made it a common material for racing cars, boats, baths & even aero planes.
