Depends on several factors. Phenolics can be sensitive to oxidizing acids (e.g. sulfuric) or to alkalis (e.g sodium hydroxide). A great way to remove phenolic is to use plasma etching, but that destroys all organic materials, so it is most useful in removing phenolic coatings from metallic substrates.
Thanks for your response. I am looking at FRP with a phenolic matrix in prepress form. Just wanted to know for experiemental purposes if there was a way to breakdown the cured resin leaving the reinforcement material behind and intack.
Thanks guys. Both interesting. In terms of the muffle furnace, what sort of temperatures would the resin burn off at and what would then need to be done to the remaining glass fibre to reuse it?
Would the plasma etching system create the same outcome as the above?
If some, in terms of energy consumption, what would be more efficient and environmentally friendly?
I was wondering if you could point me in the right direction? I am looking for some information on plasma etching in regards to phenolic materials and I can't seem to find anything. Is this process similar to the basic plasma etching tanks that are common? Also, do you know anything about the chemistry involved in the process and what the optimum RF to complete this process would be?
I am very interested in this type of technology so any kind of help would be brilliant.
