Fabrication And Characterization

Bhimal fibres are quite a newer kind of bio-degradable fibres. They have never been heard before in literatures from the view point of their utility as engineering material. These fibres have been utilized for investigation of their properties. Characterization of this fibre is essential to determine its properties for further use as reinforcing fibre in polymeric, bio-degradable and other kinds of matrix. With this objective, the fabrication method and other mechanical properties of Bhimal-reinforced-PVA biocomposite have been discussed. The stress-strain curves and load-deflection characteristics are obtained. The tensile, compressive, flexure and impact strengths have been calculated. The results are shown in tables and graphs. The results obtained are compared with other existing natural fibre biocomposites. From the observations, it has been concluded that the tensile strength of Bhimal-reinforced-PVA biocomposite is higher than other natural fibre composites. Hence these can be used as reinforcement to produce much lighter weight biocomposites.

Composite Properties

Loose hierarchical flax fibres/polypropylene composites were manufactured in a simple way based on a paper-making process in order to include nanocellulose and allow the hornification of the nanofibres in a controlled manner. The effect of flax fibre content on the flax/polypropylene composites and the influence of nanocellulose on the properties of these composites are discussed. By increasing the flax content a slight decrease of the tensile strength and an increase of the Young´s modulus were observed. On the other hand, no significant effect was noticed when increasing the bacterial cellulose content in the composites.

Fibre Reinforced Composites

Coir fibres, a byproduct of the coconut industry, have high performance qualities but are difficult to process by conventional textile methods. The purpose of the research is to combine the processibility of hemp and flax with the high-performance properties of coir to create a composite product worthy of industrial applications. The evaluation of coir fibre-reinforced composites focuses on the processibility of the coir fibre into a nonwoven, how well it interfaces with polylactic acid and an analysis of how the mechanical properties of the final product change when mixing coir with hemp and flax. The results show that the hybrid samples outperformed most of the researched values for coir composites, despite the reduced properties of control samples as in comparable research. Adding just 10% of either flax or hemp dramatically increased the mechanical properties compared to the pure coir–polylactic acid composite.

The primary purpose of this study is to determine the tensile strength and density) of the Indonesian term teki grass (Cyperus rotundus) in which this teki grass is used as the reinforcement materials for the production of fibre composite. The production process is carried out by using varieties of fiber directions ranging from 0°, 45°, 90°,and random.The methods in use is hand lay-up with 3 repetitions. Teki grass is chosen because it is easily found and has the following significances: biodegradable, harmless to health, available in nature in large quantities, and cost-efficient. Another reason because this plant is also an agricultural weed that is difficult to eradicate, not fully utilized, and often found in open field. While a matrix for fiber binder selected from epoxy resin material. From the test results it can be concluded that the variations in the direction of fibers effect on the tensile strenght of the composite. Average tensile strength of specimens with fibre directions of 0°, 45°, 90°, and random are 15.60 MPa, 18,69MPa, 30.11 MPa, and 22.79 MPa. In contrast, variations of fibre directions do not affect the density.

Purpose The purpose of this study is to develop jute-glass hybrid fibre reinforced polyester-based bio-composites using an indigenously developed pultrusion set-up and to present a detailed discussion on their mechanical characterization. Design/methodology/approach The work was carried out to observe the hybridization effect of natural and synthetic fibres in combination with hybrid fillers loading mainly on strength and other properties. The used hybrid fillers were a combination of 9 Wt.% of carbon black%, 6 Wt.% of eggshell ash powder and 6 Wt.% of coconut coir ash powder. A lab-based developed pultrusion set-up was used to develop these hybrid GJFRP composites of 1,500 mm length. The developed composites were tested for tensile strength, compressive strength and impact strength. Findings The maximum tensile, compressive and impact strength obtained are 88.37 MPa, 56.13 MPa and 731.91 J/m from 9 Wt.%, 9 Wt.% and 0 Wt.% of hybrid fillers loading, respectively. Breaking energy was found maximum as 7.31 J in hybrid glass-jute hybrid fibre reinforced plastic composites with no filler loading and it was observed that filler loading was decreasing the impact strength of developed hybrid composites. Shrinkage and its variations in the diameter of the finally developed cylindrical shape composites were observed after cooling and solidification. Scanning electron microscopy was used to observe the internal cracks, bonding of fibres and resin, voids, etc. Originality/value Development of hybrid filler based novel eco-friendly bio-composites and its experimental investigation on the impact strength, tensile strength and compressive strength has not been attempted yet.
