Reinforced plastics are a flexible material (low modulus of elasticity) yet, mechanically very strong. Subjected to a tensile stress, deforms proportionally, o sea, complying with Hooke's law, with the particularity that the rupture occurs without presenting prior creep.
Its specific gravity (1,8 Kg/dm3) is much smaller than the traditional materials, making the P.R.F.V. possesses a high specific strength.
