The recent attention that the electrostatic charge (ESC) has gotten for this decade leads to several studies and investigations for polymeric reinforced composites mechanical applications beside the ESC observation. Polymethyl methacrylate (PMMA) and High-density polyethylene (HDPE) have a proposing demand due to their own engineering applications. There are several engineering applications that lead to more interest in this type of blended materials. In the present research, the behavior of ESC generated from sliding of the composites (HDPE-PMMA) on different fabrics made of polyester (PET) and cotton is investigated. In addition, the coefficient of friction has been studied. The relation between the coefficient of friction and the electrostatic charge is stated. The results show a remarkable dependence on electrostatic charge (ESC).
