  • the film is made of more than one layers, Fig.1/5, Layers 1.1.1 , 1.1.2, 1.1.3, 1.1.4, 1.1.5, bonded together monolithically. They are 2 layers of high performance cement matrix, layers 1.1.1 and 1.1.2 incorporating the Glass Fiber layer 1.1.5 and two glue interfaces 1.1.3 and 1.1.4 penetrating the Glass fiber layer and glueing it to cement matrixes.
  • the laminates are composed of fibers of different types and materials (glass - carbon - polymers - metals) in (a) polymer or (b) metallic matrix.
  • inorganic laminates of inorganic fibers mostly Glass Fibers
  • inorganic matrices used mainly in repairing concrete or stonewall elements made by projection or patching of the matrix into the element to repair with thickness several times higher than that of the present invention and lower strength.
  • the drawbacks of (a) laminates are low strength and high deformability at elevated temperatures and high cost.
  • the drawback of (b) laminates is the high cost, whereas laminates (c) are thick and with low strength as a result on the one hand of the low strength of the cement mortars projected or cast in contact with the elements under repair and on the other due to inability of the mortar to penetrate the glass fiber bundles (usually involving 100 - 200 individual fibers), thus the bonding surface between fibers and matrix is the outer surface of the bundle instead of the sum of the outer surfaces of all the fibers of the bundle which would be many times larger.
  • the multilayer film is made up of the following layers, ref. to Fig.1/5: a.
  • the interfaces one ( 1.1.3), on top of the lower matrix and the other (1.1.4), beneath the upper matrix.
  • the Glass fiber layer (1.1.5) in form of mats or meshes with 300 - 450gr/m 2 and strength as illustrated in Table 3. This layer is penetrated by the polymer grout and is the main load bearing component of the multilayer film.
  • the grouts benetrate the fibers resulting m this way m high bond between the fibers and the top and bottom matrixes.
  • the polymers of the interfacial grout are also constitutive materials of the matrixes. In this way continuance of the film is achieved (i.e. monolithical structure made up of the penetrated Glass Fiber Layer, the interfaces and the top and bottom matrixes).
  • Sandwich components made up of individual multilayer film bonded on the top and bottom of lightweight core by means of the polymer grout.
  • the aforementioned structure of the multilayer film is composed of :
  • the mix design of the two matrixes is illustrated in Table 1 , those of the interfaces bottom (1.1.3) and top (1.1.4) in Table 2.

  • the individual multilayer films of 1 ,00m x 2,00 m weighs l ,3-2,6kg/m 2 for thicknesses 1 ,0mm - 2.0mm respectively. In this way the handling of such a film or the manufacture of any other product made of it are very easy without need of any lifting equipment.
  • the composite laminated films are made by bonding individual films together with the mix of Table 4 under pressure.
  • the number of the constitutive individual films is determined by the respective structural design, in order to satisfy the requirements on strength and stiffness.
  • the closed composite Elements, Fig.4/5, are made of individual multilayer films which are bonded on the external surface of lightweight core (2), of expanded Polystyrene or lightweight pumice or perlite, or cellular concrete, with mix design as in Table 5.
  • Fig.4.1 illustrates the plan, Fig 4.2 the long- section and Fig 4.3 the cross section of this element.
  • the Sandwich Elements, Fig 5/5, are made of individual multilayer film bonded on top and bottom sides of lightweight core of lightweight pumice, or perlite, or cellular concrete as with mix design illustrated in Table 5 and thickness depended on the loads to be applied.
  • the non-slip bond between film and core is achieved by combined action of mechanical interlocking in groves (3) and glueing along the interface (4) as illustrated in Fig.5.5.
  • Fig.5.5 involves Figures 5.1, 5.2 and 5.3.
  • the Fig. 5.1. illustrates the plan, Fig 5.2 the long section and Fig. 5.3 the cross section of the element.
  • the individual multilayer films are produced as follows:
  • a levelled working table larger than the film to be produced at least 300mm in each direction is the basis.
  • a heating film (l-2mm thick with electrical resistances) controlled by thermostat is placed. This film provides uniform heating of 45-50 which is the optimum Temperature for the process.
  • On top of this 0,80mm Aluminum film larger than the film to be produced by 50mm in each direction is placed.
