Surface finish

The surface finish on a component when taken from the mould will never be better than the surface of the mould tool from which it has been taken.  Further, it is possible that resin shrinkage during the cure of thermosetting matrix composites will reveal the topology of the reinforcement fabric - this is known as "print-through". The automotive industry dedicates considerable effort to producing vehicles which have a high gloss, consistent colour finish with minimal defects where the surface reflects a grid under controlled lighting conditions without significant distortion. This is generally referred to as "Class A" finish, but there is no rigorous definition for this parameter and hence each potential customer may have different specifications.  Wood [1] has recently considered these requirements.  Key parameters are bond-line read-through, distinctness of image (DOI), fibre print-through, orange peel, pinholes and texture.  A variety of instruments are available to "measure" the finish including the Ashland Laser Surface Analyzer (ALSA, which superseded the Laser Optical Reflected Image Analyzer (LORIA)) and the BYG-Gardner Wavescan DOI, ISRA Vision CPV (Car Paint Vision), Micro-Epsilon reflectControl and Visuol Ondulo deflectometry technology.  Further, the use of fractal dimension [2] or wavelet texture analysis [3] have been considered.
