Purpose: The purpose of this project was to estimate the possibility of using polyester-glass fiber recyclate as a reinforced component of polymer matrix in composites. This kind of mechanical recycling can be use as one of the way of polymer composites utilization. Recyclates prepared from GFP - polyester resin reinforced glass filaments. Design/methodology/approach: Recyclate obtained after grinding was a mixture of cured polyester resin particles and glass fibers. Two different groups of recyclates have been obtaining after separation. First group of recyclate was used to prepare of stratified laminates. Second group of recyclate was used as a filler of polymer matrix. Findings: The results of the investigation have shown that using of polymer composites wastes as a filler, leads to decreasing of the flexural and impact strength. However obtained material had a bending strength comparable with standard material. The results of mechanical properties have been prove that change of properties depends on the size of fraction recyclate. Fraction containing the particles in fibrous shape better influence on that mechanical properties of laminates. The results of the investigation have shown that using of polimer composites wastes as a filler materials (core), leads to decreasing of the properties in bending and impact tests. It has been shown that content of the recyclate has significant influence on studied mechanical properties. Practical implications: The results of the investigation have shown that using of polymer composites wastes as a filler, leads to decreasing of the properties in bending and impact tests. Surface treatment of recyclates has been shown that bending strength between matrix and recyclates improve. Originality/value: The results of the investigations allow to confirm, that the polymer composites waste can be used as a filler polymer matrix in production of new composites, being also one of the way of utilization of composite with thermosetting matrix.
