“…The epoxy composites reinforced with Bismarck palm fibre and Cashew friction dust particles were fabricated using the conventional hand layup method. The tensile strength of the fabricated composites was determined, and composite fabrication parameters such as fibre length, fibre volume fraction, and particle size were optimized using the Response Surface Methodology (13) . From the current state of the art, it is obvious that natural cellulose fibres and natural particles have a significant impact on polymer matrix composites.…”

Objective: In recent years, researchers have paid more attention to using natural fibres rather than synthetic glass fibres when manufacturing polymer matrix composites. Therefore, the current study focuses on fabricating and optimizing the parameters for maximizing the Flexural Strength (FS) of an epoxy composite reinforced with Bismarck Palm Fibre (BPF) and Cashew Friction Dust (CFD) particles. Methods: The water retting technique was used to extract the BPF from leaf stalk of Bismarck palm tree. The composites were fabricated by hand lay-up method. The process parameters for the research were Fibre Length (FL), Volume Fraction (VF), and CFD particle size (CFD). The experiments were developed using the Central Composite Design (CCD) method. The significance of process parameters on output response of the FS was examined using the response surface methodology (RSM). Using a scanning electron microscope (SEM), the fractured surface of the flexural specimen was examined. Findings: The results demonstrated that the optimal parameter conditions for flexural strength were a fibre length of 22 mm, a fibre volume fraction of 24%, and CFD particle sizes of 300 µm. The optimal flexural strength of the produced composite is 46.60 MPa. The most important fabrication parameters that affects the flexural strength of epoxy composites reinforced with BPF and CFD particles is known as the fibre volume fraction. The SEM images showed the various failure mechanisms such as fibre breakage, fibre tear, fibre pull out, fibre/matrix bonding, and matrix breakage. Novelty: This research is evidence that BPF and CFD reinforced epoxy composites have higher flexural strength compared to other natural fibres reinforced composites such as date palm fibres, sugar palm fibres, and date palm sheath fibres reinforced composites. The optimal parameter conditions obtained for fabricating epoxy composites reinforced with BPF and CFD particles could be used for further research.
