PET does not create a direct hazard to the environment, but due to its substantial fraction by volume in the waste stream and its high resistance to the atmospheric and biological agents, it is seen as a noxious material. Unsaturated polyester (UP) resin based on recycling PET is widely used for the matrix of composites such as fiber reinforced plastic (FRP) and polymer concrete (PC). Consequently, inexpensive and high performance resins are important for the future of polymer composites. One recent method for enhancing the performance of polymer composites are the manufacture of MMT...
