TL;DR: In this article, the sisal fiber was grafted with methacrylonitrile (MAN) under UV radiation in order to modify its mechanical and degradable properties.
Abstract: The sisal fiber (Agavae sisalana) was grafted with methacrylonitrile (MAN) under UV radiation in order to modify its mechanical and degradable properties. A number of MAN solutions of different concentrations in methanol (MeOH) along with photoinitiator Darocur-2959 were prepared. The soaking time, radiation dose and monomer concentration were optimized. Sisal fiber soaked for 60 min in 50% MAN and irradiated at 8th UV pass achieved highest values of tensile properties like tensile strength (TS = 140.2 MPa), and elongation at break factor (Ef = 8) with 8% polymer loading (PL). To further improve the properties of sisal fiber, a number of additives (1%) such as urea (U), polyvinylpyrrolidone (PNVP), tripropelene glycol diacrylate (TPGDA), hexanediol diacrylate (HDDA), trimethyl propane triacrylate (TMPTA), ethylene glycol dimethacrylate (EGDMA) were used in the 50% MAN formulation to graft at the optimized condition. Among the additives used, urea has significantly influenced the PL (9%), TS (190 MPa), and...

TL;DR: In this paper, an experimental study was conducted to investigate joint efficiency of both, butt, and lap joints of sisal CSM reinforced polymer composites, where thermoplastics, HDPE, and polypropylene (PP) were used separately as matrices in composites.
Abstract: An experimental study was conducted to investigate joint efficiency of both, butt, and lap joints of sisal CSM reinforced polymer composites. The thermoplastics, HDPE, and polypropylene (PP) were used separately as matrices in composites. Sisal-HDPE composites exhibited excellent improvement in tensile strength that reached up to 47.5 MPa at 30 phr loading of sisal CSM as compared with 17.7 MPa of HDPE. Significant improvement in HDT was also observed that increased from 60.2 to 75°C on 0 to 30 phr reinforcement of sisal CSM in HDPE. Similar improvement was noticed with PP where in HDT improved from 69 to 87.6°C on incorporation of 0 to 30 phr sisal CSM. Hot tool welding process was employed for joining the composite materials. The joint efficiency of butt joint of HDPE was observed as 30%. It varied from 48 to 59% for lap joints of different sizes. The joint efficiencies of 20 mm lap joints of different compositions were observed as 59, 98, 75, and 58% in 0, 10, 20, and 30 phr Sisal CSM-HDPE composites, respectively. Welded joint strengthening is attributed to partial reinforcement of interface that occurs during softening of matrix material which allowed spring back of originally pressed fibers followed by their repositioning in the welded part.

TL;DR: In this paper, a detailed characterization of fiber-reinforced polymer (FRP) composites has been carried out by utilizing naturally occurring fibres from sisal, jute, banana, and ramie plants.
Abstract: Advantages of composite materials based on natural fibre have warranted increased utility of these products and have significantly offset the use of artificial fibre composites. This work on preparation of fibre-reinforced polymer (FRP) composites has been carried out by utilizing naturally occurring fibres from sisal, jute, banana, and ramie plants. Two sets of FRP composites have been prepared (1) by chemical treatment and (2) without chemical treatment. Detailed characterization of FRP composites prepared has been carried out. Detailed procedures for preparation of the samples have been explained. Parameters like tensile strength, flexural strength, water absorption, density, and microstructure analysis are performed. For density measurement, Archimedes concept using air and water weight measures and ASTM C830-00 guidelines have been followed. KIC-2-1000-C is employed for tensile tests, and digital weighing method is adopted for water absorption analysis. The FRP prepared have a great potential as natural fibre polymer composites (NFPCs) and constitute for a wide range of applications. A significant improvement in these properties has been obtained by heat and chemical treatment of these composites. Satisfactory improvements of the properties were noticed with heat and chemically treated fibre-reinforced composites. Tensile and flexural strength tests were carried out on untreated and treated sisal, jute, ramie and banana fibre-reinforced composites, which revealed significant improvement of treated composites (tensile strength 73.59, 41.70, 36.30 & 33.87 N/mm2 and flexural strength 60.77, 40.47, 72.05 and 31.54 N/mm2, respectively) as compared to untreated composites (tensile strength 57.24, 37.72, 35.19 and 21.83 N/mm2 and flexural strength 50.51, 40.27, 41.77 and 21.35 N/mm2 respectively).
