“…The surface roughness measuring lengths of WPC’s were generally rather short: 4 mm 27 or 12.5 mm. 2,3,5 However, in this research, the specimens (four replicates for each WPC combination) were scanned on tracing lengths of 50 mm, because longer tracing length gave more accurate results.…”

This study extensively investigated the surface roughness of injection molded wood plastic composites (WPCs) produced from different amounts of wood flour, polymer matrix, mineral filler, and other additives. A larger range of roughness parameters that used in the previous literature were obtained from nine different WPC compositions by using a robust filtering method (robust Gaussian regression filter) to have a better understanding of the overlaying quality of the WPC samples. Three melt flow index (MFI) of the polymer were tested (MFI 3.6, 12, and 25). It was found that WPCs produced with the polypropylene having a MFI value of 25 were the smoothest. It was noticed that not only the wood flour percentage matters but the combination of wood flour–mineral filler was also important. The WPC compositions with lower polymer amount in favor of more wood flour and mineral filler led to rougher surfaces. A decrease of wood flour in favor of increasing the mineral filler participation percentage had a surface smoothing effect. At the same wood flour content, a decrease in polymer combined with an increase in mineral filler led to rougher WPC surface. Among the tested WPC compositions, the smoothest surface was obtained in the specimens produced from 50% wood flour, 0% mineral filler, and around 40% polymer by weight. The results should be helpful to anticipate the effect on surface roughness of the percentage participation for each amount of the wood or mineral filler, polymer matrix, and additives in further development of WPC combinations.

“…[1], [3]The main reasons for such a large and continuous expansion of the use of plastic materials are:  the plastics is a substance of low density, yet reduces the overall weight of the product,  the plastics exhibit low thermal and electrical conductivity, therefore, are often used as insulating materials,  plastics are easily molded -plastics are usually highly resistant to corrosion, and are characterized by low degradability (aging). [5] Plastics waste produced in the manufacture, treatment or use in industry and in the social and individual consumption as a municipal waste.…”

Plastic waste as a separate component (fraction) of waste management can be defined as waste from production and consumption. Waste from the production and is also characterized as industrial waste and waste from manufacturing processes. It formed directly in the production and finalization of the semi product. It is basically the best quality plastic waste. Its advantage is the fact that it is almost always a waste of single-well-defined and well-known material from which it is largely possible to do full recycling products. Recycling of this material type in Slovak republic is relatively well settled. Waste from consumption i.e. mainly waste from used products and packaging may occur on two levels and a waste eg. from supermarket chains, warehouse, industry (industrial packaging), waste from municipal sector.etc..

“…Even in cutting, the amount of wooden reinforcement in wood-plastic composites affects the shape of the formed chips. 19 In Treviso et al, 20 it was stated that although not widely exploited yet, fibrereinforced polymers have the potential to be tailored for damping by acting on constituents, geometry, and boundary conditions.…”

The present work contributes to the research on the damping properties of fibre composites through an experimental approach by using the free damped vibration measurement based on impulse-force system response, the developed measurement stand and laser Doppler vibrometry. Moreover, the influence of the material configuration on the damping properties was investigated and was compared with conventional homogeneous isotropic materials. The measurement was based on the analysis of flexural vibrations generated by the Dirac impulse force, as well as on the free decayingvibrations response; the time-and frequency-domain modal identification was employed. The fibre composites were represented as layered bidirectional long carbon-and glass-fibre composites (laminates) with different material configurations and as short carbon-fibre composites.
