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.
Highlights
In recent years, the increasing pressure of environmental volunteers, the protection of natural sources, and the harshness of the laws enacted by the state lead to the discovery and improvement of natural materials
The mechanical characteristics of composite samples produced with jute fabric, 49 gr/m2 glass fiber fabric, 100 gr/m2 glass fiber fabric, and epoxy resin was determined at three different post-curing temperatures (60, 80, and 100 °C)
The temperature rising from 60 °C to 100 °C in JG100 samples caused a 28.67% decrease in tensile strength
Summary
The increasing pressure of environmental volunteers, the protection of natural sources, and the harshness of the laws enacted by the state lead to the discovery and improvement of natural materials. Natural fiber composites have advantages such as less dependence on non-renewable energy sources as environmentally friendly materials, increased energy recovery, lower pollutant emissions and greenhouse gas emissions, and biodegradability of components at the end of their life cycle [1]–[3]. Hybridization with more than one type of fiber in the same matrix material diversifies the properties of fiber reinforced composite materials [5]. A material can be created that has the combined advantages of the individual components and reduces their fewer desirable qualities. Hybrid composites can increase the impact and fatigue resistance, the toughness of the material compared to individual reinforced material, and can provide the material with better strength, high stiffness, and reduce the material weight and total cost [6], [7]. Composites that fiber reinforced are increasingly made use of in automotive and marine applications, coating industry, aviation applications, aircraft, and safety equipment due to their extraordinary properties [8]–[10]
