Abstract

In this work a PIMC (Powder InMould Coating) process for continuous fiber-reinforced composite components in automobile exterior applications has been developed. The aim of the coating was to prevent the formation of pinholes and fiber print through. Thus generating a surface ready for class A painting in a pro-cess suitable for mass manufacture. On specimen plates, produced through hot press curing, the influence of the prepreg material as well as the coating and the curing were observed. The ob-tained results were used to derive new powder formulations and develop several coating processes. The achieved Class-A capability was analyzed on different finishes by means of Wavescan measurement and 3D Focus Variation microscopy. During these measurements the climatic aging resistance of the systems was examined On the Way to realize real three-dimensional automotive parts it was necessary to produce at least simple parts as technology carrier. These demonstrated impres-sively that a Class-A surface can be generated in a fully automated process within a short cycle time.
