Abstract
A new attempt development of new hybrid composite materials has been studied. Increasing the mechanical and physical properties of composite materials to lower their weight and cost is the most frequent problem in engineering projects. This study's goal is to enhance the mechanical and physical characteristics of composite materials. Also due to this, hybrid composite materials have received recent attention. In this work, hybrid composite materials were created to enhance mechanical and physical characteristics. In this investigation, glass fiber and mica fiber were both employed as synthetic and natural fibers, respectively. The influence of mica as natural fiber with glass fiber as synthetic reinforcement by weight percent (wt%) on the mechanical properties of hybrid composite materials were investigated. Epoxy resin (thermosetting polymer) reinforced by various wt % of glass fiber/mica fiber, such as (0-0, 15-0, 10-5, 7.5-7.5, 5-10, 0-15 %), as well as samples created by hand lay-up method. In addition, glass fiber and mica fiber in long fiber unidirectional form are utilized; mechanical properties such as tensile, flexural and impact strength have been tested. As the results of this study, both glass fiber and mica fiber increased mechanical properties, although glass fiber has a greater effect than mica fiber but also using mica fiber make great improvement between 26% to 67%. Composites reinforced with 15% glass fiber had a better value of mechanical properties compared to others. Additionally, the hybrid composite made of glass fiber and mica fiber performed well in all tests, enhanced mechanical characteristics, which decreased the cost of making composites.
