The fabrication process of thermoplastic composites using hybrid fabrics composed of yarns made of glass and PA6 fibres as prepregs is presented. The influence of the structure of hybrid yams produced using commingled, texturising, twisting and friction spinning technology on the mechanical properties of composites is discussed. The results of the investigation indicate that the best tensile and bending properties of composites were achieved using fabrics made from texturing yarns produced under optimal conditions. These optimal conditions should ensure the minimum destruction of filaments during the blending process.
