FRP Advantages

• High traction resistance

• Low specific weight

• Resistant to environmental stress

• High lightness

• Quick laying

• Non-invasive interventions

• Mass and geometry do not change after strengthening

The use of composite materials began in the thirties of last century within the industry and in the sixties they began being widely used in many fields, such as (civil and military) aeronautics, the naval-marine sector or mechanical field. Only the field of civil construction began to use composites after several decades; in fact composites became more and more common during the last decade, so that the drawing of instructions by the CNR was necessary in order to regulate their use. This phenomenon is due to the high versatility that composite materials have in the field of structural strengthening; it is also due to their numerous advantages, compared to the building common materials. In fact composite materials have a resistance about ten times greater than that of steel; moreover they are resistant to corrosion and, thanks to their lightness, they make the laying very fast. Therefore, they allow, in a quick and not intrusive way, the strengthening of reinforced concrete, masonry, metal and wooden structures, so they can be used at 360° in problems of structural recovery and monumental restoration.
