Abstract
  • A hybrid coating is described, for reinforced composite polymer materials to be used for structural mechanical applications in which a high geometric stability is required. The composite materials has lightweight and stiffness properties, but are subjected to geometric distortions due to the humidity absorption being present in the atmosphere or following the accidental contact with fluids in the working environment in which the composite itself is used. Purpose of this coating is conferring to a composite material properties that improve its dimensional stability and that therefore prevent alteration of the dimensions of structures made of the affected material. Such coating is obtained by means of a Plasma Enhanced Chemical Vapour Deposition (PECVD) process. Preferred embodiments of such coating are realised by using, as precursors, organosilane monomers (for example hexamethyldisiloxane or HDMSO) combined with oxygen (O2), and possibly argon (Ar).The coating is composed of two layers. The most internal layer is humidity-proof, and therefore operates as protecting barrier for the composite material on which it is applied. The layer more on the surface has water-repellence characteristics and is composed of the same chemical elements present in the more internal layer but with different percentages and with a different stiochiometry. Among the composite materials on which it is possible to lay this coating, there are, for example, materials reinforced with aramide (ex. Kelvar), carbon (CFRP) or glass (GFRP) fibres. Among the structural applications of said composite materials in which a high geometric stability is required, there is, for example, the field of operating machines. (literal)
