Effect Of Water

Incorporating natural fibre as reinforcement in the polymer matrix has shown a negative effect since the natural fibre is hydrophilic. The natural fibre easily absorbs water which causes an effect on the mechanical properties of the composites. The objective of this paper is to investigate the water absorption behaviour of hybrid jute-roselle woven fibre reinforced unsaturated polyester composite and the effect of water absorption in terms of tensile strength and tensile modulus. The effect of hybrid composite on the thickness swelling will be tested. The fabrication method used in this study is the hand lay-up technique to fabricate 2-layer and 3-layer composites with layering sequences of woven jute (J)/roselle (Ro) fibre. The results of the study showed that pure roselle fibres for 2 and 3-layer composites have the highest water absorption behaviour 3.86% and 5.51%, respectively, in 28 days) as well as thickness swelling effect, whereas hybrid J-Ro and J-J-Ro composites showed the least water absorption (2.65% and 3.76%, respectively) in 28 days) in both the tests. The hybridisation between jute and roselle fibres reduced water absorption behaviour and improved the fibres dimensional stability. The entire composites showed a decreasing trend for both tensile strength and tensile modulus strength after five weeks of water immersion. Jute fibre composite hybridised with roselle fibre can be used to reduce the total reduction of both tensile strength and tensile modulus throughout the whole immersion period. Moreover, the tensile testing showed that jute fibre composite hybridised with roselle fibre have produced the strongest composite with the highest tensile and modulus strength compared to other types of composites. The hybridisation of diverse fibre reinforcements aids in minimising the composite water absorption and thickness swelling, hence reducing the effect of tensile characteristics.

The natural fibre composite materials are nowadays playing a vital role in replacing the conventional and synthetic materials for industrial applications. This paper proposes a natural fiber composite made of Abaca fibre as reinforcing agent with Epoxy resin as the matrix, manufactured using Hand Lay-up method. Glass Fiber Reinforced Plastics (woven rovings) are used to improve the surface finish and impart more strength and stiffness to natural fibers. In this work, the fibers are arranged in alternative layers of abaca in horizontal and vertical orientation. The mechanical properties of the composite are determined by testing the samples for tensile and flexural strength. It is observed that the tensile strength of the composite material is dependent on the strength of the natural fiber and also on the interfacial adhesion between the reinforcement and the matrix. The composite is developed for automobile dashboard/mudguard application. It may also be extended to biomedical, electronics and sports goods manufacturing. It can also be used in marine products due to excellent resistance of abaca to salt water damage since the tensile strength when it is wet.

Kenaf fibres have acquired enormous attention in recent years, owing to their economic viability and environmental acceptability. Kenaf (natural) fibres have been started to replace the glass fibre (synthetic) in mechanical, electrical applications and have been utilized in several applications of industrial engineering. The current study deals with water absorption of kenaf/glass fibre reinforced unsaturated polyester composite materials used in high voltage polymeric insulator rods. The kenaf/glass hybrid composites were based on 20%, 30% and 40%(by volume) of kenaf fibers replacement glass fibres with modified 60 vol.% unsaturated polyester resins. The composites were immersedin distilled water at room temperature, and composites resistance to water absorption in terms of the rate of water absorption was determined.A considerable difference in the properties of water absorption of the hybrid composite was found demonstrating that the water absorption effect on the characteristics of insulator rods depends on the arrangement and volume fraction of kenaf fibre of the composite used. Based on the results obtained, a slight effect of water absorption on pure glass fibre composite (control) was observed. The addition of kenaf fibre on glass fibre composite rod increased the water absorption of the composite. It was shown that glass fibres surrounding kena ffibre reduced water absorption. Despite the fact that 40 vol.% of kenaf fibre composite had the highest natural fibre content, it showed the lowest water absorption because of its arrangement on all composite diameters, and also because of being surrounded by glass fibres. All of the materials reached equilibrium and ceased to absorb water after 300 hours

Composite materials are a class of materials used in many diverse applications. Very recently the attention has shifted to the development of green composites that are easily recycleable and in this case the use of biodegradable matrices and fibres appear to be highly attractive. In the present study a class of biodegradable polyesters are used as matrices to produce fully biodegradable composites, reinforced with lignocellulosic natural fibres. This new class of composites is fully biodegradable, but the key aspect that governs the behaviour of the composites remains the interface. Surface treatments, although having a negative impact on economics, may improve the compatibility and strengthen the interface in natural fibre composite materials. In the present study the effect of two surface treatments, namely acetylation and propionylation, upon the interface of natural fibre composites is assessed by means of fragmentation tests. It has been found that both treatments led to an improvement of the stress transfer efficiency at the interface, and both applied treatments were optimised, accordingly.

Nowadays, natural fibre-thermoplastics composites (NFPC) are replacing the conventional wood and timber due to its lower cost, avoid deforestation, higher strength-to-weight ratio and resistant to termites. These composites can be utilized for non-structural components of a building system such as decking, wall cladding, floor tiles and window frame. A natural fiber/plastic composite was produced by extrusion molding process to create a wall cladding profile. The raw materials used for the composites are 40% kenaf fibre and 60% polypropylene (PP). These materials were compounded through a twin-screw extruder and then cut into pellets. The moisture content found in the kenaf/PP composites (KPC) pellets was 2.89%. Therefore, the pellets required to be oven dried every time right before entering the hopper of the extruder. The temperature along the barrel was set to 180°C and the die head temperature is set to 165°C. At the end of the extrusion molding process, pressurized air was used for cooling the profile. Then, samples of the wall cladding were taken back to the laboratory for product quality assurance. Measurements of the samples show that the product experiences 3% of shrinkage in term of width and 1% of shrinkage in term of thickness. Water absorption test indicates an increase of 13.6% of weight after 24 hours immersion of water. Impact strength test was also conducted on the wall cladding samples and the mean result was 2.55 kJ/m². Tensile test on the extruded KPC product indicates a low tensile strength at 4.51 MPa and tensile modulus of 205.01 MPa. The sample also proven to be light weight as the density of the material was found to be 0.618g/cm³.

The amount of rubber seed waste in Indonesia is highly yielded as a side product from a large amount of rubber trees plantation. The rubber seed was not processed become the usefull application yet, thus it becomes a high volume of waste in each year. An initiative should be done to turn it as a practical material. The rubber seed is potential for natural composite along with the increasing attention toward natural composite application.This work aims to produce natural fibre composite based on rubber seed and characterize it's mechanical properties. In this work, the rubber seed natural composite produced by using the hand lay-up method. Polyester resin YUCALAC BQTN-157 was used as the matrix with the addition of 1% MEKP (Methyl-Ethyl-Ketone- Peroxide) as the catalyst. Mechanical properties of the composite were examined by using a tensile and bending test. Additionally, the water absorption test was performed according to the ASTM D 570. The result showed that the tensile and bending strength decrease with increasing the filler composition, which is added in the composite. The composite, which has the filler composition of 40% was generate the highest tensile strength. In contrast, the lowest tensile strength appeared at the composite with a filler of 60%. The bending strength trend also behaves similarly with the tensile strength as the filler composition increased. Water absorption ability of composites displays the acceptable value as it shows within the range of 2.22-2.96%.

Natural fibre composite materials have been highlighted in recent years as they have the potential to mitigate the pollution and global warming. Kenaf is a high yield and fast growing plant. Kenaf does not require a lot of energy in production. Furthermore, the kenaf plant can absorb carbon dioxide when breathing. The objective of this paper is to relate the effect of different environment to the mechanical properties of kenaf and kenaf hybrid (fiberglass) polyester composites for 60 days period. Kenaf composite (containing 20 wt% of Kenaf fibres) and kenaf hybrid (containing 20 wt% kenaf fibre and 16 wt% fiberglass) were produced in cold press hand lay-up technique and then cured for 24 hours. The specimens were cut as required in EN ISO 527. The specimens were immersed in 3 different water sources, which were rain water, salt water and tap water. Tensile and hardness test were conducted to study the mechanical properties at 10, 20, 30, 40, 50 and 60 days. Both kenaf polyester and kenaf hybrid polyester show reduction on mechanical properties after immersion in the solutions. Kenaf polyester and kenaf hybrid polyester followed fickian behaviour after 40 days water immersion.
