The article deals with the possibilities of using recyclate, prepared by shredding waste fibre reinforced polymer (FRP), in building materials. As the first step, the influence of disintegration parameters on the properties of the output product of FRP recycling was investigated. The outputs in the form of chips of suitable granulometry and shape parameters were further verified for use in chipboard for structural purposes. The effect of chip size and binder content on the physico mechanical parameters of the chipboard was evaluated. Higher flexural tensile strength was achieved when lower chip lengths were used - the opposite trend was observed regarding the impact toughness. Functionally graded specimens with variable chip lengths were also prepared and the effect of gradation on the mechanical parameters of the chipboard was assessed. The results were compared with commercial particleboard and wood chip-based materials, and the competitiveness of the developed new FRP recyclate-based materials was confirmed.
