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

摘要: Abstract The surface topography of carbon fiber reinforced plastic composites after machining processes like milling or grinding has a complex character due to the inhomogeneous material structure. usual procedure evaluate is given with usage parameters that describe one more specific features surface. In mechanical engineering, for example, roughness Ra, Rz, Rmax and Rt have been established tactile-based measurement devices. However, applicability several not always suitable composites. this work influence positions, distribution measured values behavior these in respect machined structure are analyzed by means optical as well tactile measurements. This results recommendations measurability surfaces plastics using profile methods an assessment derived parameters.
