With the aid of Injection Moulding Machine (IMM) Palm fiber reinforced Acrylonitrile Butadiene Styrene (ABS) composites (PF-ABS) were prepared. Three sets of samples were prepared for three different wt% (5%, 10% and 20%) of fiber contents. Scanning Electron Microscopy (SEM), X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FTIR) experiments were performed to study the surface morphology, microstructure (if it crystalline or noncrystalline) and new bond formation after preparation of the composites. SEM pattern shows that after addition of palm fiber in PF-ABS composites the brittleness increased due to creation of voids in the composites except 10% fiber content in PF-ABS. From XRD pattern it is clear that the palm fiber, ABS and PF-ABS composites are amorphous in nature. Moreover FTIR spectrum shows that there is no new bond formed after addition of palm fiber in ABS polymeric matrix to create PF-ABS composites.

The challenge of replacing conventional plastics with biodegradable composite materials has attracted much attention in product design, particularly in the tensile-related areas of application. In this study, fibres extracted from oil palm empty fruit bunch (EFB) were treated and utilized in reinforcing polyester matrix by hand lay-up technique. The effect of fibre loading and combined influence of alkali and silane treatments on porosity and water absorption parameters, and its correlation with the tensile behaviour of composites was analyzed. The results showed that tensile strength decreased whilst modulus of elasticity, water absorption and porosity parameters increased with increasing fibre loading. The composites of treated oil palm EFB fibre exhibited improved values of 2.47 MPa to 3.78 MPa for tensile strength; 1.75 MPa to 2.04 MPa for modulus of elasticity; 3.43% to 1.68% for porosity and 3.51% to 3.12% for water absorption at respective 10 wt.% fibre loadings. A correlation between porosity and water absorption with tensile behavior of composites of oil palm EFB fibre and positive effect of fibre treatment was established, which clearly demonstrate a connection between processing and physical properties with tensile behavior of fibre composites. Accordingly, a further exploitation of economic significance of oil palm EFB fibres composites in areas of low-to-medium tensile strength application is inferred.

Polyester, date palm fiber, compression, young's modulus, flexural strength, thermal conductivity. This research has been done by reinforcing the matrix (unsaturated polyester) resin with natural material (date palm fiber (DPF)). The fibers were exposure to alkali treatment before reinforcement. The samples have been prepared by using hand lay-up technique with fiber volume fraction of (10%, 20% and 30%). After preparation of the mechanical and physical properties have been studied such as, compression, flexural, impact strength, thermal conductivity, Dielectric constant and dielectric strength. The polyester composite reinforced with date palm fiber at volume fraction (10% and 20%) has good mechanical properties rather than pure unsaturated polyester material, while the composite reinforced with 30% Vf present poor mechanical properties. Thermal conductivity results indicated insulator composite behavior. The effect of present fiber polar group induces of decreasing in dielectric strength, and increasing dielectric constant. The reinforcement composite 20% Vf showed the best results in mechanical, thermal and electrical properties. How to cite this article: M.H.

Wood has some weaknesses, such as susceptibility to weathering, easily attacked by termites, and low water resistance. An alternative material such as Natural Fibre-Reinforced Polymer (NFRP) composite should overcome those weaknesses. This research aims to make a composite with palm fibre and unsaturated polyester resin. Palm fibres immerse for 2 hours in NaOH solution with varying concentrations of 3%, 5%, and 7%. The volume fraction of palm fibre are 0%, 5%, 10%, 15%, and 20%. Woven roving fibreglass was added to compare the tensile strength of composite with or without natural fibre. The density of composites increased with the increase of fibre volume fraction. The highest tensile strength was obtained for 15% of fibre volume fraction, namely 23.8483 MPa. In contrast, the highest compressive strength was obtained for 5% of fibre volume fraction, namely 94.76 MPa. NaOH removed the impurities and waxy substances from the fibre surface and created a rougher surface topography after...

The research work is focused toward determining the static and dynamic mechanical properties of the composites made by reinforcing untreated and alkali-treated short palmyra palm leaf stalk fibers (PPLSF) of length 3 mm, , and 10 mm in the polymer matrix. The short palmyra palm leaf stalk fiber reinforced polymer matrix composites are prepared by a compression molding method. The result illustrates that the 7 mm alkali-treated short PPLSF composite exhibited the maximum tensile strength of 45.13 ± 1.57 MPa, the flexural strength of 71.35 ± 2.57 MPa and impact strength 10.21 ± 2.13 kJ/m 2. The dynamic mechanical analysis shows that the 7 mm alkali-treated short PPLSF composite has improved the storage and loss modulus compared to 3 mm and 10 mm short untreated and alkali-treated fiber composites. Further thermogravimetric analysis carried out for 3 mm, 7 mm, and 10 mm untreated and alkali-treated fiber-reinforced composites showed that the thermal characteristics of the composites have improved due to treatments as well due to increase in fiber length. The tensile-fractured surface of the composites is also examined with SEM to identify the mechanism of failure.

This research investigates the effect of alkali treatment and the coupling agent to the mechanical properties of oil palm reinforced polymer composites. The polypropylene was used as the reinforcement matrix whereas the oil palm fibres were used as the reinforcement fibres. The oil palm fibres were prepared in two conditions namely alkali treated and untreated fibres. During the composite material preparation, the untreated fibres were prepared in two conditions; i.e. without coupling agent and with coupling agent. Here, the coupling agent used was the Polypropylene grafted Maleic Anhydride (PPgMA). The fibres were determined at 10% for all specimens. All specimens were mechanically tested for Charpy impact and tensile tests. The results show that the impact strength and the ultimate tensile strength were not influenced by the alkali treatment. However, alkali treatment significantly increases both strain percentages at the ultimate tensile and at the break points. It was also observed that by adding the coupling agent, the impact strength and the strain percentage at ultimate tensile and break points were improved significantly. However, the tensile strength of the specimens were not influenced by the coupling effect. This finding was essential in determining the influence of coupling agents in polymer matrix composite strength.
A review on oil palm empty fruit bunch fiber-reinforced polymer composite materials
Polymer Composites, 2010
Natural fiber-reinforced polymer composite materials have emerged in a wide spectrum of area of the polymer science. The composite produced from these types of materials are low density, low cost, comparable specific properties, and most importantly they are environmental friendly. The composite materials produced from oil palm fibers and commercially available polymers have offered some specific properties that can be comparable to conventional synthetic fiber composite materials. However, these properties are greatly dependent on the compatibility of oil palm fibers and matrix phase with moisture absorption as one of the critical issues that becomes the drawbacks of the oil palm fiber polymer composite materials. Apparently, it greatly affects the physical as well as mechanical properties of the composite materials. The present review reports the work on oil palm empty fruit bunch (OPEFB) fiber-reinforced polymer composites with some interest on the OPEFB physical structure, and chemical compositions. Finally, the incorporation of OPEFB into polymeric materials leads to several interesting consequences on the water absorption characteristics and the mechanical properties, which have been reviewed.

In the present technological aspect, the innovation and development need to be better in order to meet the needs of present practical application and by having a balance in economic and environmental factors. The reinforced composite is a widely used polymer in recent days. These materials have efficient mechanical characteristics which include strength, heat resistant, good conduction, resistance to correlation, and are rigid in nature. When a reinforced composite is combined along with other natural fibers the outcome of these composite will meet the requirements that are expected from them. In this research paper, the mechanical characters of Arecanut Palm along with epoxide composite and fiber-reinforced polymer composite are utilized. the composite is fabricated using the stir casting method. According to the American Society for Testing and Materials, the obtained composite has been crushed into a small composite for the purpose of other experiments. The specimens to be utilized for the experiment have undergone certain checks like hardness, mechanical testing, and density test. The fiber-reinforced polymer along with areca nut palm fiber showed a significant result in hardness, density, flexural strength, and tensile strength. The obtained composite has been fabricated with 10wt% of reinforced areca nut palm epoxide composite. The structure of the fiber and its matrix has been analyzed using SEM analysis.

Natural fibres offer environmental benefits such as biodegradable and can be obtained from renewable resources. However, there is lack of investigations done to characterize and compare different types and orientation done on the natural fibres. This paper determines the tensile strength of sugar palm fibres under various treatment processes. The composites were fabricated using woven sugar-palm fibre treated with alkali and acid and used epoxy resin as the matrices for the composite. The tensile test was done to determine the tensile strength of the composite and the surface morphological analysis was done using SEM. The results demonstrated that the composite with the alkali treated fibres produced higher tensile strength compared to untreated and acid treated fibres. With these properties, it shows that treated woven sugar-palm fibre composite can withstand high stress load during operation compared to untreated fibres reinforced composites.
Natural fibers nowadays have become attractive to researchers as an alternative to synthetic fiber to be used as reinforcing element in terms of strength, modulus and hardness. These include low cost, high specific strength, good mechanical property, non-abrasive, corrosion resistance, biodegradability in comparison to conventional glass, aramid and carbon fibers. Flexural properties are mainly influenced by the interfacial bonding between fiber and matrix. Conventional Hand-lay-up technique was adopted for preparing composites, Firstly, Hardness of each specimen had been taken. Then, composites were made by aligning untreated fiber, 2%NaOH and 4%NaOH treated palm leaf fiber into the matrix (polyester resin). There is a gradual increase in the value of the yield strength and modulus ranging from pure composite to untreated fiber, then to 2%treated fiber and then to 4% NaOH treated fiber reinforced composites. These experiments were repeated using 10 multiplication load condition to further investigate the enhancement of flexural strength, modulus and hardness comparing to unloaded condition observed.
