Studies on the effect of treated sugar palm fiber with alkaline treatment and benzoylation treatment on single fiber tensile strength and interfacial shear strength (IFSS) are shown in this paper. Also shown is the tensile strength of treated sugar palm fiber composite with variable fiber loading (10%, 20% and 30%). For alkaline treatment sodium hydroxide (NaOH) was used, while benzoyl chloride (C7H5ClO) was used in benzoylation treatment. Polymer matrix that was used in the process of making sugar palm fiber composite is epoxy resin with hardener. For the single fiber test and IFSS, the alkaline treatment was carried out using 1% concentration of sodium hydroxide for one hour soaking time while 5ml of benzoyl chloride was used to agitate with sodium hydroxide for benzoylation treatment with variable soaking time (10, 20 and 30 minutes). Treated sugar palm fiber showed higher single fiber strength and IFSS compared to untreated fiber due to the efficiency of both treatments which help rearrangement of fibrils along the tensile force direction. Tensile properties of sugar palm fiber composite show improvement in tensile stress and tensile modulus for treated sugar palm fiber composite while tensile strain show the opposite result. This is because the bonding strength between fiber and matrix increased by removing the outer layer together with impurities from the fiber during chemical treatment. Thus, with this treatment method, sugar palm fiber can be use as reinforcement material for composite and use them for commercial use such as for furniture and component inside vehicle.

This paper aims to study the surface morphology, flammability and tensile properties of sugar palm fiber (SPF) hybrid with polyester (PET) yarn-reinforced epoxy composite with the addition of magnesium hydroxide (Mg(OH)2) as a flame retardant. The composites were prepared by hybridized epoxy and Mg(OH)2/PET with different amounts of SPF contents (0%, 20%, 35% and 50%) using the cold press method. Then these composites were tested by horizontal burning analysis, tensile strength testing and scanning electron microscopy (SEM) analysis. The specimen with 35% SPF (Epoxy/PET/SPF-35) with the incorporation of Mg(OH)2 as a flame retardant showed the lowest burning rate of 13.25 mm/min. The flame took a longer time to propagate along with the Epoxy/PET/SPF-35 specimen and at the same time producing char. Epoxy/PET/SPF-35 also had the highest tensile strength of 9.69 MPa. Tensile properties of the SPF hybrid with PET yarn (SPF/PET)-reinforced epoxy composite was decreased at 50% SPF content due to the lack of interfacial bonding between the fibers and matrix. Surface morphology analysis through SEM showed uniform distribution of the SPF and matrix with less adhesion, which increased the flammability and reduced the tensile properties of the hybrid polymeric composites. These composites have potential to be utilized in various applications, such as automotive components, building materials and in the aerospace industry.

AbstractThis experimental study was conducted to investigate the effect of NaOH concentration and treatment time on the flexural properties ofLuffa cylindricafiber-reinforced epoxy composites. Significant improvement (up to 84.92%) in the flexural properties for the treated fiber composite compared with the untreated fiber composite was observed. Both treated and untreated fiber composites were then subjected to different environmental treatments (saline water, distilled water, and subzero temperature). To find out the changes in flexural strength immediately after treatment, the same test was carried out on the composites. Degradation in the flexural strength of both treated and untreated fiber composites, when subjected to environmental treatments, was observed. They were found within the range of 2%–20% and were found to be least in subzero treatment. The SEM micrograph indicates that alkali treatment is effective in improving the adhesion between the fiber and matrix.

Properties Of Composites

The use of natural fiber as reinforcement for epoxy polymer composites is currently a concern for researchers because it is environmentally friendly so it can replace glass fiber or carbon in engineering applications. Palm fiber is a type of natural fiber that is produced by the cooking oil industry as a component of waste. The surface modification of fiber with NaOH solution is one of the factors that determines level of adhesion to the epoxy polymer matrix. This study to analyze the effect of alkali treatment on the morphology and characteristics of fiber. In addition, the effect of palm fiber composition on the mechanical properties of composites were studied. Alkali treatment on fiber was carried out using 10% wt sodium hidroxide solution. The morphology and characteristics palm fiber before and after alkali treatment were analyzed using SEM-EDX, XRD, and FTIR. Tensile tests were carried out on composites with treated fibers and without treatment with sodium hidroxide solution. The results showed that alkali treatment caused the surface morphology of the fiber to be finer due to the loss of lignin and hemicellulose components. Alkali treatment fiber can increase the tensile strenght. Composites with fiber and resin composition of 4%: 96% wt that have undergone alkali treatment have a maximum tensile strength of 21.60 MPa.
