Purpose: of this paper is to develop a new generation of polymer composite materials that
would ensure the use of residual and serious environmental problems of polyester-glass
laminate waste.
Design/methodology/approach: The glass reinforced polyester waste was ground and
added to produce new composites. Thermoplastic - high impact polystyrene was selected
for the composite matrix. Composites containing 10, 20, 30% by weight of the filler of
polyester-glass laminate powder were made. The process of extrusion and subsequent
injection was used to prepare the test samples. The influence of the filler on selected
properties of composites was evaluated. The physical properties of the filler as well as the
processing properties of the mixture as well as the mechanical properties - impact strength
and tensile strength of the obtained composites were investigated.
Findings: A decrease in tensile strength and impact strength was observed along with an
increase in the amount of filler.
Research limitations/implications: It would be interesting to carry out further
analyzes, in particular with a higher volume fraction of the filler or with a different composite
structure, e.g. using PVC as a matrix. The developed research topic is a good material for
the preparation of publications of a practical and scientific nature, especially useful in the
research and industrial environment.
Practical implications: The shredded glass-polyester waste can be used as a filler of
polystyrene, however, the resulting composite could be used to produce parts with slightly
less responsible functions such as artificial jewelery or toy elements.
Originality/value: Obtained results are a new solution a global waste management solution
for glass reinforced polyester waste, which may contribute to the sustainable development
of the composite materials industry through the partial utilization of waste composites with
a duroplastic matrix.
