IMPROVEMENT OF THE DAMPING PROPERTIES OF CARBON-FIBRE-REINFORCED LAMINATED PLASTICS USING DAMPING LAYERS

摘要

A suitable hybrid composite consisting of carbon-fibre-reinforced plastic and damping layers was investigated in terms of damping and natural frequencies using experiments and numerical simulations. The frequency response and the transient response of cantilever beams were analysed. The damping layers made from rubber or from a cork-rubber composite material were used in the investigated hybrid structure. A laser-measurement device and an accelerometer were used for the measurement of the responses. Pareto optimization was performed using three-dimensional numerical simulations with the aim to maximize the fundamental natural frequency and the damping ratio.
