To enhance the mechanical characteristics for engineering applications, this work aims to produce a unique bio composite that incorporates natural fiber. At 0, 10, 20, and 30% weight fractions, kenaf fiber (KF) is used to strengthen biopolymer poly-butylene succinate (PBS). An injection molding machine was used to create the polymer composite by adding chopped KFs to the molten PBS. A comparison is made between the prepared composite and plain PBS in terms of their machining characteristics, namely drilling. A control group consisting of unreinforced PBS and an experimental group consisting of PBS with KFs added. There were four groups given consideration. Using the G-Power calculator, three samples were analyzed for each group, each with a probability of 0.05 and a 95% confidence interval. Along with increasing their stiffness and hardness, chopped KFs added to PBS also increase their mechanical strength. Measurements are made of the amount of fiber delamination when a solid carbide tool is drilled in a vertical machining centre. A substantial difference between the groups under consideration is found in the analysis, with a significance level of 0.000 (p<0.05). This indicates that the degree of delamination rises when more KFs are included. Though its mechanical strength is greater, adding KFs to the PBS matrix, under the parameters of this investigation, results in increased delamination because the fibers pull out of the matrix during drilling.

Natural Fibre Reinforced Plastic Composite material that the Kenaf Fibre are used to reinforce to the polymer matrix to improve its mechanical properties. It is environmentally friendly and low cost as compare to non-biodegradable material. It is also widely used in Aerospace, Automotive and Furniture industry. Drilling process plays an important role in fabrication in these industries. However, some defects often occur on the Natural Fibre Reinforced Plastic Composite during drilling process. The major damage is delamination that are found on the surface of the composite in drilling process. This damage reduces the mechanical properties of the composite. Therefore, the objective of this study is to investigate and minimize the delamination by using Response Surface Methodology (RSM). Cutting speed and feed rate are found significant to delamination in this study. The higher the previous researchers investigate the cutting speed with low feed rate, the lower the delamination. Therefore, the conclusion of this study is high cutting speed with low feed rate improve the mechanical quality of composite. [ABSTRACT FROM AUTHOR]

Due to Environmental ill effects and rising synthetic fibre costs natural fibres have found a prominent use as reinforcement in polymer composite. To significantly improve the required mechanical properties, hybridization of adequate proportions of natural fibre and synthetic fibre has proved useful. Hybridized composite retains the parent properties of its constituent particles. The newness in the constituent particles of the composite is the need of the world. This article focuses on development technique of kenaf and glass fibre epoxy composite. Hand layup technique is used for making samples in the mould. The impact on mechanical properties like bending and impact is also discussed. Varying volume fraction and treatment with alkaline solution of constituent particles has shown changes in impact and bending properties. Sample with 30% fibre with treatment of alkaline shows highest bending strength and impact strength of untreated sample with 15% kenaf fibre shows maximum impact strength. [ABSTRACT FROM AUTHOR]
