We point out a plasmachemical nanotechnology that is worthwhile for preparation of thin and ultrathin films of controlled mechanical properties. Organosilicon thin films have been deposited on planar substrates and analysed employing nanoindentation measurements with respect to the Youngs modulus of films and adhesion bonding at the film/glass interface. The modulus of plasma-polymerised film can be controlled simply by the effective power fed into the capacitive-coupled low-pressure plasma. The homogeneous film was tested as an interlayer for GF/polyester composites. Glass fibre (GF) bundles were surface modified by plasma polymer in a unique technological system enabling continuous processing of the bundle. GF/polyester composites in a form of short beams have been fabricated using the coated fibres and tested according to the standard test method. By increasing the effective power (interlayer modulus), the short-beam strength has enhanced up to 112% in a comparison with untreated glass fibres and that enhancement has been supported by an improvement of interfacial bonding as well.
