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.

The Difference

Manila hemp fibers are separated to several sequent fragments from single fiber. The tensile strength of each fiber fragments and their epoxy composite are measured, followed by scanning electronic microscopic (SEM) analysis. The results show that the tensile strength of fiber fragments is almost constant along fiber. For composite, the tensile strength first increases and then decreases at the position near to root. The Young's modulus presents increasing with location from root to top for fiber and composite. Microstructure analysis indicates that the difference of tensile properties between fiber fragments derive from the difference of fiber diameter.

Water Effects

Effects of sea water immersion for palm fiber in relation to surface morphology, roughness and bonding between the fiber and sago matrix were observed. Duration of immersion varied in 1, 2, 3 and 4 weeks, and then dried at room temperature for 3 hours continued by oven at 80 °C for 6 hours. SEM and roughness arithmetic tests were applied to see surface morphology, roughness and bonding between fiber and the matrix. Result shows fiber morphology and roughness varies by the duration of immersion. The surface roughness increases as immersion continues along with fiber - matrix bonding improvement. The maximum duration of 4 weeks fiber immersion resulted in the best interlocking of matrix and fibers, as the slits between them disappear.

The flame retardant mechanism of magnesium hydroxide sulfate whiskers(MHSH) is analysed and MHSH and magnesium hydroxide are used to fill high-density polyethylene(HDPE) respectively. The mechanical and flame resistance properties of composite material (HDPE) were also studied in this paper contrastively. The tensile strength and elongation of the compound are increased 2.5% and 36% severally, while MHSH content in weight reaches 20%;at the same time, the oxygen index (OI) of composite materials varies from 17 to 24.2. In contrast, the tensile strength and elongation of the HDPE/ Mg(OH)2compound are decreased 6.4% and 48% respectively, OI being 19.6. To sum up, the results of tensile and flame tests of compound material showed the HDPE containing as-prepared whiskers had better overall properties，exceeding that of Mg(OH)2.

Denim Fabric

Denim washing is not such an old thing that is not known to us. It is done to get proper aesthetic look of the fabric. Denim washing or somehow called as denim finishing has its own scope in the market or industrial scale as it enhances the functional activity as well as the make fabric aesthetically more appealing This research work focuses on the different washing techniques of denim fabric keeping the environment as major concern with enzyme (Lava Cell NHC, bio-polish (Lava Cell NBP, enzyme and stone, resin (PULCRA STABITEX ETR+dip and resin spray. For this purpose, the leg tubes of 22×22 inches of denim fabric are made and prescribed recipes are applied on the fabric in an automatic tumble TONELLO machine. After that different tests were performed to investigate change in dimensional, pilling resistance, tensile Strength, tear Strength, absorbency and change in shade variation after different washing. And surface morphology of fabric samples after washing was investigate by SEM analysis.

Sugar Palm Fiber

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.
