Abstract :In this study, it was aimed to recycle waste polystyrene (PS) to obtain PS composite with high screw withdrawal strength that can be used in the core layer of composite wood sandwich panels. For this purpose, waste MDF dust (MF) and glass fiber (GF) were used as fillers in the PS matrix. Waste PS was first dissolved in gasoline and then 50-100-150 % fillers were added and mixed. The solvent in the composite was removed from the composite with two different temperatures. Thickness swelling (TS) and water uptake (WA) amounts of the samples and screw withdrawal strength (SR) were analyzed for mechanical characterization. According to the analysis results, it was determined that as the MF ratio increased, there was no significant change in the TS, but the WA increased. MF filled composites has more TS than GF filled composites. However, it was determined that the WA in GF filled composites was higher than in MF filled composites. The fillers increased the densities except for the addition of 150% GF. SR analysis results showed that the addition of filler increased the SR of composites. As a result, waste PS can be converted into a material with high screw withdrawal strength by adding waste MF and GF and can be used instead of wood material.Keywords : Polistiren, Geri dönüşüm, Atık, Cam elyafı, MDF tozu
