Annotation: The dissertation aimed to develop fibre-reinforced polymer composites with high mechanical and multifunctional properties based on matrix modification and nanocoating with electrically conductive MXene nanoparticles. The work analyses the mechanical and electrical properties of MXene nanocomposites and nanocoatings, both experimentally and numerically. The characterisations of MXenes were performed using XPS, AFM and SEM, while wettability properties were obtained by measuring the contact angle of polar and non-polar liquids. Multiscale homogenisation methodology was developed using 2D and 3D finite element models based on inverse modelling techniques. The influence of geometrical parameters, distribution, interface strength and volume fraction on MXene-polymer nanocomposite mechanical properties was investigated numerically, while the influence of surface roughness, temperature, UV radiance and mechanical deformations on MXene nanocoating’s electrical properties was investigated experimentally. MXene coating’s piezo-resistivity was analysed under static tensile and cyclic loadings. Moreover, coating’s Joules heating was performed and tested for de-icing of the composite.
