An Investigation into the Mechanical Properties of an Epoxy-Based Composite Made From Jute Fiber and Reinforced With Sal Tree Gum Powder

Because of their adaptability to the needs of each given technical application, composite materials may be used in various contexts. In order to investigate the influence that bio-fillers influence on epoxy composites, sal tree gum powder has been included in the epoxy resin matrix; the hand-laid procedure is used to make composite specimens using varying volume fractions. Testing was done to ascertain the epoxy composite's mechanical properties, such as its resistance to impact and ability to withstand tensile and flexural stress. Based on the results, it was discovered that the best mechanical qualities were created by a 20% filler volume and a 20% fiber volume. A limit is placed on the material's flexural strength of 87 MPa, tensile strength of 51 MPa, and impact strength of 3950 J/m2. According to the DMA findings, the composite's glass transition temperature ranges from around 95 to 105 °C for frequencies ranging from 1 to 10 Hz. In addition, thermogravimetric analysis was carried out using the powdered sal tree gum used as a particulate filler ingredient in the epoxy matrix. Morphological characteristics were examined by analyzing images obtained from scanning electron microscopy (SEM) of specimens shattered by stress. © 2023, The Institution of Engineers (India).
