Effect on the mechanical properties and water absorption of granite powder composites on toughening epoxy with unsaturated polyester and unsaturated polyester with epoxy resin

In this article a study on the tensile, flexural, compression, and impact strength of granite powder-epoxy composites on toughening epoxy with unsaturated polyester and unsaturated polyester with epoxy resin has been assessed. The water absorption studies revealed that an increase in the strength of the composites showed a positive toughening effect. The morphology study has also been carried out in order to study the interfacial region in the composites.
