IISc breakthrough for recycling Carbon Fiber Reinforced Polymers

03-Oct-24

A research group at Indian Institute of Science, Bangalore has made a breakthrough to recycle CFRP composites

Carbon fiber reinforced polymers consist of carbon fibers embedded in a polymer matrix. Epoxy resin, a thermoset, is a very common choice for the polymer matrix. IISc scientist led by Prof. Suryasarathi Bose and Prof Subodh Kumar has developed a bio based aqueous solution that can break down the resin and recalim teh carbon fiber fabric. The recycled epoxy and carbon fiber were found to maintain structural integrity and can be used in new composites or blended with other polymers to create new products
The epoxy can also be put ot use as a hardener to design other materials

This technique will simplify the recycling process and help the composite industry achieve a circular economy
