    Effect of flame retardants on performance of PALF/ABS composites
    (2013) Poonsub Threepopnatkul; Thanaphat Krachang; Wipawee Teerawattananon; Katawut Suriyaphaparkorn; Chanin Kulsetthanchalee
    This research is to study the effect of two different flame retardants i.e., bisphenol-A bis (diphenyl phosphate) (BDP) and 9, 10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) on the flammability and mechanical properties of the composites of modified natural pineapple leaf fiber (PALF) reinforced acrylonitrile butadiene styrene (ABS). A 10% by weight of such PALF was compounded with ABS using diisononyl phthalate 1% w/w as plasticizer at the different flame retardant concentration (10 and 20 wt%) in a co-rotating twin screw extruder. An injection molding machine was used to prepare the specimens. The effects of flame-retardants showed that the PALF/ABS composite containg DOPO showed superior performance in terms of flammabitily. Higher content of flame retardants led to increase LOI value. Moreover, the composites added DOPO produce enhanced mechanical properties such as young's modulus and tensile strength. © (2013) Trans Tech Publications, Switzerland.

    Pineapple leaf fibers (PALF) are abundant to the agricultural products which are native to the tropical climate region. It also exhibit excellent tensile strength and tensile modulus. Acrylonitrile butadiene styrene (ABS) copolymer possess several prominent properties such as strength, rigidity and toughness. Both ABS and PALF are at high risk to the fire hazard when used in daily life. The improvement of flame retardancy of composite materials has been the priority for the safety requirements of natural fiber composite products. This research is aimed to study the effect of two different phosphate compounded flame retardants i.e., bisphenol-A bis (diphenyl phosphate) (BDP) and 9, 10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) on the flammability, mechanical and thermal properties of the composites of modified natural pineapple leaf fiber reinforced acrylonitrile butadiene styrene. 10% by weight of such PALF was compounded with ABS using diisononyl phthalate 1% w/w as plasticizer at the different flame retardant concentration (10 and 20 wt.% of ABS). The effects of flameretardants showed that the PALF/ABS composite containing DOPO showed enhanced performance in terms of flame retardancy and even act as self-extinguisher. Higher content of flame retardants led to increase limiting oxygen index value. Moreover, DOPO added composites produced superior mechanical properties such as young's modulus and tensile strength. Furthermore, both thermal degradation temperature of PALF/ABS composites with DOPO and thermal degradation temperature of PALF/ABS composites with BDP showed relatively lower temperature than the ones of PALF/ABS composites. © Smithers Information Ltd., 2014.

    Study of surface treatment of pineapple leaf fiber (PALF) on performance of PALF/ABS composites
    (European Conference on Composite Materials, ECCM, 2012) P. Threepopnatkul; T. Krachang; W. Teerawattananon; K. Suriyaphaparkorn; C. Kulsetthanchalee; P. Threepopnatkul; Department of Materials Science and Engineering, Faculty of Engineering and Industrial Technology, Silpakorn University, Nakhon Pathom 73000, Thailand; email: poonsubt@yahoo.com
    This research is to study the influence of surface treatment for pineapple leaf fiber (PALF) on the mechanical properties of PALF reinforced ABS composites (ABS/PALF). PALF was pretreated with sodium hydroxide (PALF/NaOH), cellulase enzyme treatment and modified with N-2(aminoethyl) 3-aminopropyl trimethoxysilane (PALF/silane) to improve interfacial strength of the composites. PALF with different surface treatment methods were characterized using Fourier Transform Infrared and Scanning Electron Microscopy technique. The composites were tested mechanical properties by Universal Testing machine. The results show that the modified PALF composites lead to the enhancement of mechanical properties such as young's modulus. Young's modulus is the highest for PALF/NaOH/Cellulase composites. PALF/silane composites possessed the highest tensile strength and impact strength among all the treated system.
