support, sea yachts.
An improved effective technology of production of a three-layer monolithic sheathing whose
carrying layers are made of a polyether fiber glass reinforced plastic, produced
layer-by-layer molding or of a preproduced semi-finished products.
The polyether fiber glass-reinforced plastic is environmentally safe, ensures habitability
conditions, is hard to inflame, with low speed of the flame propagation along the surface
(calorimetryc coefficient,Kmax is 0.6; a flame propagation index along the surface, I, is
12.
Strength and elastic characteristics of the three-layer glass reinforced plastic with
density of 0.91 g/cm^ meet the requirements to structural materials of ships and vessels
sheathing.
Can operate in an atmosphere and in aqueous media at temperatures from ~^C to +60^C.
Application of valuable types of wood and expensive production power consuming low
magnetic steel and aluminium-magnesium alloys are excluded.
High efficient technology of hull structure with a low number of hull set beams providing
a simplification of the construction technology while keeping a high level of strength and
service reliability.
Increased transversal strength and impact strength as compared to the three-layer fiber
glass plastic with central layer of PHV. High strength and stiffness are combined with low
density.
