Abstract [en]

The aim of this research was to analyze the mechanical and thermal properties of composites and hybrid composites prepared with four types of jute fibers and two different resins; biobased thermoset resins acrylated epoxidized soybean oil (AESO) and mathacrylated anhydride modified soybean oil (MMSO). The processing technique used was vacuum injection molding (VIM). Tensile and, flexural testings and dynamic mechanical and thermal analysis (DMTA) were used to characterize the composites’ properties. The results showed that the AESO composites have better tensile and flexural properties. This may be due to the fact that the curing conditions were quite the same for both AESO and MMSO composites but MMSO composites showed different behavior during curing step. They were completely cured in a shorter time compared to AESO composites. Having equal curing time for both resins’ composites can damage the structure of MMSO composites and hybrids. Tan delta peak for the MMSO reinforced composites occurs at higher temperatures, compared to AESO reinforced composites, which means better thermal properties for MMSO reinforced composites.
