Abstract Two types of push-out tests were carried out at the Centre of Research and Innovation in Construction, the Technical University of Košice - one at a composite based on steel continuous shear connector and the second one at the same connector, however made of glass-laminate material. For further research, the material characteristics of the material used needed to be found. In this article, the material tests performed as well as their results are presented.

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.

Abstract FeSiB metallic glass laminate is a state-of-the-art structure for improving the magnetic performance of magnetic core. Extreme strength and hardness due to the amorphous matrix challenge its grinding process with severe tool wear and pronounced delamination. An amount of heat generated during grinding process brings a considerable problem in material crystallization, resulting in an increased magnetic deterioration. In this work, grinding data is presented for grind wheel wear, cutting force and surface quality when routing 8 mm thick FeSiB metallic glass laminate using electroplated CBN grinding points. Grinding experiments were carried out with grinding speeds of 0.5 and 1.5 m/s to investigate the formation of delamination. Energy dispersive x-ray spectroscopy (EDS) and electron back scattered diffraction pattern (EBSD) analyses were conducted to inspect the delamination between the metallic foil layers and detailed microstructure of machined surface, respectively. The relation between the cutting force and delamination was discussed associated with the identification of crystallization condition of machined surface. As a result, plastic deformation between the layers is the primary reason for the inter-laminate circuit short. Load-displacement curve from nano indenter indicated the strain hardening level near machined surface increased with cutting speed.
