The objective of this paper is to demonstrate the superiority in terms of soft skin effect of CF/PP. First, we defined soft skin effect as an ability to reduce stresses or forces, its rates, and vibration applied to human body by light impact. Next, drop weight impact test and FEM analysis were performed and following conclusions can be obtained. (1) In the case that human body collides with CF/PP products directly, the developed CF/PP shows high ability to reduce human’s pain and discomfort because of its surface softness and low inertia. (2) In the case that human body is protected by the CF/PP from impact loads of the colliding object, the new CF/PP shows high ability to reduce back face force and its speed because of its excellent damping property. Therefore, the soft skin effect of the developed CF/PP is superior to that of steel and aluminum. Such human friendly features of the CF/PP are useful to expand its applications.
