Abstract
In this study, the effect of different curing temperatures (60°C,80°C, and 100°C) on the mechanical characteristics of Jute and Glass fiber-based hybrid composites were analyzed mechanically, physically, and morphologically. Jute fiber fabric and glass fiber fabrics (49 gr/m² and 100 gr/m²) were used as reinforcement elements, while epoxy was utilized as ma-trix materials. A vacuum assisted resin transfer molding method (VARTM) was used as the production method. The mechanical test results were achieved by the Tensile test and Vick-ers hardness test, while morphologic images were obtained by Scanning Electron Microsco-py (SEM). Physical data was also obtained by the ignition loss test. The effects of tempera-ture and hybridization on mechanical properties of hybrid composite samples formed with jute fabric and glass fiber material with different weights per square meter at different cur-ing temperatures are given in the results. Results show that increasing post cure temperature 60°C to 80°C 3.18%-3.41% rate augment in tensile strength. It was discovered that there was a decreasement in tensile strength with an increase in temperature from 80 °C to 100 °C after curing. In the hardness test results, increasing post curing temperature had an increas-ing effect on the hardness values. SEM analysis results also supported the tensile test re-sults.
