The size reduction of waste polymers has become an important subject in the field of waste reclamation.
Therefore the investigation carried out on the impact and compressive fracture energy of synthetic resins by using four kinds of unsaturated polyester resins whose rheological properties are different. The specific fracture surface energies were determined by means of flexural impact tests and compressive tests with different rates of loading.
It was found that the values of specific fracture surface energy were greatly influenced by the nature of resins and their viscous flow priperties and that the fracture energy was dependent on the load velocity.
