Cover Story Machining of CFRP

In the machining lightweight sector prejudices against influence of processing fluids to material properties of FRP have still prevailed. Rhenus Lub, developer and producer of lubricants, has investigated more detailed the interactions between special processing fluids for composites and CFRP in cooperation with the German Aerospace Centre.

In metalworking industry the application of metalworking fluids during machining processes is widely spread. In cooling and lubricating the contact zone between tool and workpiece not only an extension of tool life but also an improvement of surface qualities is possible [1]. For fibre reinforced plastics (FRP) processing fluids are only rarely used. According to a survey of the year 2014 more than 50 % of the users machine dryly and only 16 % use flood cooling [2].

Because of very small and respirable particles encapsulation and extraction are necessary during dry machining [3]. Delamination and protruding fibres are frequent results of dry...
