Purpose: In this paper the possibilities of application of polyester-glass fiber recyclates in composite’s materials were estimated. Different materials with addition of recyclates were made: laminates stratified laminates and polymer concrete. Design/methodology/approach: Recyclate obtained after grinding was a mixture of cured polyester resin particles and glass fibers. Two different groups of recyclate shave been obtaining after separation. Recyclate with grain size of 0,063-2,0 mm was used to prepare of stratified laminates. Recyclate size below <0,063 mm was used as filler of polymer matrix in laminates. In first group of composites recyclate was used as core in lamitates reinforced wowen or mat fabric. The value of using recyclates obtained 25, 35, 45 and 55% wt. Findings: The results of the investigation have shown that using of polymer composites wastes as a filler, leads to decreasing of the tensile, bending and impact strength. However obtained material had bending strength comparable with standard material. The best properties were achieved for the laminates with two layers of glass mat as a surface layer. It has been shown that the content of the recyclate has small influence on the studied mechanical properties. The values of bending strength, impact strength for the laminates were evaluated and compared with analogical properties appointed for standard sample. The results of the investigation have shown that using of polymer composites wastes as a filler materials (core), leads to decreasing of the measured properties in bending and impact tests. It has been shown that content of the recyclate has significant influence on studied mechanical properties. In the case of second group of recyclate (size below 0,063 mm) was used as a filler in polymer matrix. In case the stratified laminates with addition of 4wt., 10%wt., and 20%wt. of recyclate were made. Practical implications: The results of the investigation have shown that using of polymer composites wastes as a filler, leads to decreasing of the measured properties in bending and impact tests. It has been shown that content of the recyclate has significant influence on studied mechanical properties. Originality/value: The results of the investigations allow to affirm, that the polymer composites waste of small granulation can be used as a filler polymer matrix in production of new composites, being also one of the way utilization of composite with thermosetting matrix.
