Zero-Waste Recycling of Shelf-Cured Pre-Impregnated Carbon Fiber Reinforced Epoxy Laminae

The main objective of this study was to investigate a zero-waste restoration and reprocessing method of carbon/epoxy prepreg. We studied a series of chemical and thermal treatments to reshape and re-strengthen pre-impregnated (prepreg) carbon fiber-reinforced polymer (CFRP) composite rolls that were cured over the shelf, never been used, and would otherwise be discarded. The proposed treatment method is of high interest in minimizing solid waste...
