TL;DR: In this paper, the sisal and E-glass fabrics were integrated with the epoxy matrix and silicon carbide filler to enhance the flexural properties of composite laminates.
Abstract: Development of the Polymer based Composites from both natural and synthetic fibers is a sustainable alternative material for some engineering fields like automotive and aerospace. This work is aimed to incorporate the sisal and E-glass fabrics with the epoxy matrix and by adding silicon carbide filler to the sisal fabrics. Five different composite laminates were prepared by hand layup combined with vacuum bagging method as per laminate sequences. The physical and mechanical properties of composite laminates were evaluated according to ASTM. Results show that incorporation of E-glass and silicon carbide filler can reduce the voids and enhance the physical properties. As the amount of E-glass fibers slightly grows, tensile properties of composites grow. Effect of filler can enhance the flexural properties. Failure of composites mainly occurs due to the poor interfacial bonding between fabrics and matrix, fabrics pull out and fracture occurs in fabrics or matrix when load is applied.

Abstract: The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. Natural fibers are sustainable materials which are easily available in nature and have advantages like low-cost, lightweight, renewability, biodegradability and high specific properties. The sustainability of the natural fiber-based composite materials has led to upsurge its applications in various manufacturing sectors. In this paper, we have reviewed the different sources of natural fibers, their properties, modification of natural fibers, the effect of treatments on natural fibers, etc. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials.
