The Influence of Two Extra Carbon Fiber Layers over the Damping Properties for Sandwich Bars with Polypropylene Honeycomb Core

Abstract:

In this paper we will build some new and original composite sandwich bars reinforced with two and four layers of carbon fiber (in the upper and lower sides), with the core made of polypropylene honeycomb. Starting from the dynamic response of these bars that are in free vibration, we will establish a procedure to determine their damping factor per unit mass and per unit length. The bars will have the polypropylene honeycomb core with 10 and 15 mm and the width of 45 mm. The bars will be clamped at one end and free at the other. We will consider several free lengths of: 200, 230, 260, 290, 320 and 350 mm. We will highlight how the damping factor will increase if two extra carbon fiber layers are added in the upper and lower sides of the sandwich bars.
