This method uses the sulfuric acid digestion method to determine the resin content of carbon fiber reinforced plastics. The principle is to use heated sulfuric acid to completely decompose the resin matrix. It is suitable for carbon fiber reinforced plastics that sulfuric acid can completely decompose the resin matrix without excessively corroding the fibers under certain conditions.
