Thu, 01 Oct 2015 00:00:00 GMT

Title: Natural fiber reinforced polyester based biocomposite: agro waste utilisation Authors: Hazarika, S B; Choudhury, S U; Panja, S S; Dolui, S K; Ray, B C Abstract: This study presents using of locally available betel nut fiber waste as reinforcement for composite preparation by hand layup and compression molding technique. Mechanical properties such as tensile strength, flexural strength and impact strength of the composites with volume fraction (10, 20, 30 and 40 %) were evaluated. Thermal properties and water absorption capacity were also investigated. Results are statistically analyzed and found improvement in mechanical strength of these composites compared to virgin polymer. Page(s): 589-594

Palm Fatty Acid Distillate based biodiesel: characterization and Emission analysis

Thu, 01 Oct 2015 00:00:00 GMT

Title: Palm Fatty Acid Distillate based biodiesel: characterization and Emission analysis Authors: Metre, A; Nath, K Abstract: Biodiesel obtained from the acid catalyzed esterification and trans-esterification of palm fatty acid distillate (PFAD) was characterized using gas chromatographic and Fourier transform infrared spectroscopic analyses. Physico-chemical and thermal properties of the biodiesel were evaluated and compared in relation to that of conventional petro-diesel following ASTM and Indian standards. The PFAD-biodiesel blended with different proportion of petro-diesel was also subjected to performance and emission tests at varying loads in order to evaluate its actual performance, when used in a four stroke diesel engine. Exhaust gas analysis showed appreciable reduction of CO₂ and hydrocarbons as against the unblended petrodiesel, although reduction of CO was marginal. Page(s): 584-588

Title: Mechanical and electrical properties of Jute-Biomass-Styrenated Methacrylate Epoxy Resin sandwich composites Authors: Patel, J V; Patel, J P; Bhatt, R D; Parsania, P H Abstract: Sandwich composites of jute-biomass (banana, sugarcane, coir, wheat husk and groundnut)–styrenated methacrylate epoxy resin of 1,1’-bis(4-hydroxyphenyl) cyclohexane have been fabricated by compression molding technique at 110 ^OC and 2 Bar pressure for 5 h. J-EBCMASt., J-B-EBCMASt, J-SC-EBCMASt, J-CO-EBCMASt, J-W-EBCMASt and J-GN-EBCMASt showed respectively tensile strength of 34.5,17.1, 11.4, 11.9, 20.7 and 13.1 MPa, and flexural strength of 32.3, 21.6, 28.3, 11.2, 52.1 and 22.1 MPa, electric strength of 1.6, 1.2, 1.5, 1.3, 1.3 and 1.4 kV/mm and volume resistivity of 5.9x10¹², 2.5 X 10¹²,4.7 X 10¹¹,5.3 X 10¹²,3.2 X 10¹²and2.3 X 10¹² ohm cm. Considerably lower mechanical and electrical properties of sandwich composites are due to different nature of biomass and random orientation. The composites may be useful for low load bearing housing and electrical applications. Page(s): 577-581
