Mechanical and Flame-Retardant Properties of Exoxy Epikote 240/Epoxidized Linseed Oil Composites Using Fiber-Glass

Abstract

Flammability of polymer composite appears to be one of the greatest threats and hence limits its advanced applications. Polymer composite materials can be designed to obtain wide ranges of properties in comparison with traditional materials. However, almost common polymers include the intrinsic flammability, restricting their applications in spite of their flexibility and performance efficiency. In this study, a material based on epoxy Epikote 240 resin 90 phr and epoxidized linseed oil 10 phr was prepared. In order to improve the material's flame retardancy ability but maintain its mechanical strength, the mixture of flame retardants including 9 phr antimony trioxide and 11 phr chlorinated paraffins along with amin compounds as a curing agent were added into the material. In addition, E-glass woven fabric (E 600g/m2 ) was used to improve mechanical strength of the material. As a result, the material was considered as the flame- retardant material with LOI index to be 30.3%.
