Characterization of the Surface Roughness of Milled Carbon Fiber Reinforced Plastic Structures

In this work the influence of the measurement positions, the distribution of the measured values and the behavior of these values in respect to the machined surface structure are analyzed by means of optical as well as tactile surface measurements. This work results in recommendations for the measurability of machined surfaces of carbon fiber reinforced plastics by using tactile profile methods and an assessment of the derived roughness parameters.
