Evaluation of Impact Resistance and Interlaminar Shear Strength in Hybrid Composites of Kevlar, Hemp, and Carbon Fibers for Structural Applications
Year: 2025
Type: article
Abstract: The hybrid composites made using both synthetic and natural fibers are an ecofriendly alternative to conventional construction materials. This paper investigates the effect of hybridization of Kevlar, hemp and carbon fibers in the matrix of epoxy on impact resistance and interlaminar shear strength (ILSS). The composites were fabricated using the hand layup technique. Then, they were tested and evaluated for interlayer bonding contribution to resist shear stress. The results demonstrate that the impact resistance values (12.5 J and 15.8 J for 3 mm and 5 mm specimens, respectively), and ILSS values (6.8 MPa and 8.4 MPa) are superior on comparing with other materials (asbestos, cement and galvanised iron). The lightweight design and ecological advantages also make the composites well suited for use in roofing, cladding and protective structures.
