This study included the study of surface hardness Shore-D and the wear rate of the Hybrid Systems  of polymer Matrix  composite that were prepared in this study. The results showed the role of Quercus wood  by raising the characteristics of the other wood added to it. Both hardness and wear resistance values ​​were observed in conjunction with the hybridization process which improved the properties of the plastic composites ER -
