“…According to Vilaseca and fellow researchers (2007), fiber-matrix interaction can be due to mechanical friction, van der Waals forces, hydrogen bonds, and covalent bond formation between the fiber and matrix. Natural fibers are more suited to this purpose than synthetic ones because they bear similar surface polarity (arising from the -OH groups on both which, in turn, facilitates the formation of hydrogen bonds between the fiber and the matrix TPS) with starch, a property that promotes good interfacial interaction (Wollerdorfer and Bader 1998;Vilaseca et al 2007). In addition, they are inexpensive, lightweight, non-abrasive, renewable, and biodegradable, and also possess high strength-to-weight ratio (Morton and Hearle 1975;Bürger et al 1995).…”

“…Extrusion is also mostly used for starch plasticization (Matzinos et al 2002). Although extruded fiber-reinforced composites show improved mechanical properties compared with the unreinforced, extrusion compounding as well as injection molding has been found to cause some fiber damage (particularly fiber length and diameter reduction) during processing (Wollerdorfer and Bader 1998;Puglia et al 2003;Grande and Torres 2005;Vilaseca et al 2007), a condition that may limit optimum realization of fiber reinforcing potentials.…”

Effects of Incorporating Polycaprolactone and Flax Fiber into Glycerol-Plasticized Pea Starch

et al. 2011

The environmental menace associated with the existing eco-unfriendly conventional plastics prompted the exploration of natural polymers such as starch for the development of biodegradable plastics. These efforts have seen starch used in various ways, one of which is in the processing of thermoplastic starch (TPS). Thermoplastic starch (also known as plasticized starch) is the product of the interaction between starch and a plasticizer in the presence of thermomechanical energy. While starch blends with conventional plastics only yield products that biofragment, thermoplastic starch (TPS) offers a completely biodegradable option. However, it is limited in application due to its weak mechanical strength and poor moisture resistance. To this end, the objective of this study was to determine the effects of incorporating polycaprolactone (PCL) and flax fiber into glycerol-plasticized pea starch. The effects of processing moisture content on the physical properties of glycerol-plasticized pea starch were also evaluated. The physical properties investigated included morphology, tensile properties, moisture absorption, and thermal properties. Accordingly, two thermoplastic pea starch mixtures containing 9.3 and 20% processing moisture contents were prepared while maintaining starch (pea starch) and glycerol in ratio 7:3 by weight (dry basis). Polycaprolactone was then compounded at 0, 10, 20, 30, and 40% by weight in the solid phase with the TPS mixtures to determine the effects of processing moisture content and PCL incorporation on the physical properties of glycerol-plasticized pea starch.This experiment was structured as a 2 x 5 factorial completely randomized design at 5% level of significance. Subsequently, PCL and flax fiber were iii compounded with the TPS mixture containing 20% processing moisture to determine the effects of PCL (0, 20, and 40% wt) and flax fiber (0, 5, 10, and 15% wt) incorporation on the physical properties of glycerol-plasticized pea starch. This was structured as a 3 x 4 factorial completely randomized design at 5% level of significance. All the samples were compressed at 140°C for 45 min under 25000-kg load. The compression-molded samples were characterized using scanning electron microscopy (SEM), tensile test, moisture absorption test, and differential scanning calorimetry (DSC) techniques.The tensile fracture surfaces showed a moisture-induced fundamental morphological difference between the two TPSs. The TPS prepared at 20% processing moisture content revealed complete starch gelatinization, thus, exhibiting a rather continuous phase whereas the TPS prepared at 9.3% processing moisture content revealed instances of ungelatinized and partly gelatinized pea starch granules. Consequently, the tensile strength, yield strength, Young's modulus, and elongation at break increased by 208.6, 602.6, 208.5, and 292.0%, respectively at 20% processing moisture content. The incorporation of PCL reduced the degree of starch gelatinization by interfering with moisture migration during compr...

“…As jute is abundantly available in tropical countries, it is worthwhile to study jute-polyethylene composites with an aim to achieve comparable properties of other filled polyethylene composites. A lot of research works are going on to improve the quality of the composites more [6][7][8][9][10][11][12][13] and most of the articles reported only mechanical properties. But, in this investigation both mechanical and electrical properties specially dielectric constant and loss tangent of untreated and chemically treated jute fiber reinforced LDPE composites have been investigated.…”

Jute fiber reinforced low density polyethylene (LDPE) composites (10-30% fiber, by weight) are prepared by compression molding. Tensile strength (TS), bending strength (BS) and bending elongation (BE) of the composites are increased over LDPE. Jute fiber is treated with monomer (2-hydroxyethyl methacrylate, HEMA) along with two different initiators in methanol solvent. Jute fibers are soaked with 10% HEMA+2% Irgacure-184 (F1-Formulation) and 3% HEMA+2% benzol peroxide (F2-Formulation) and dried at 80ºC for 2 hours then composites are fabricated by compression molding. It is found that due to chemical treatment of the jute fibers, a significant improvement of the mechanical properties of the composites are happened (56% TS, 30% BS and 35% BE) compared to the LDPE. 3%HEMA+2% benzol peroxide treated jute composites found better mechanical properties compared to 10%HEMA+2% Irgacure-184 treated jute composites. Dielectric constant and loss tangent of the composites are increased with increasing temperature up to a transition temperature and then decreased, finally reached to plateau. Scanning Electron Microscopic (SEM) analysis of the fracture side of the composites are carried out and supported better fiber-matrix adhesion due to the chemical treatment.

In this paper presented the behavior of nano jute fiber composite under impact loads by varying percentage of weight fractions of jute fiber, as interlayer of glass fiber epoxy composite. Impact strength of the composite is the requirement to know the ability of the material under impact loads. The ratio of glass fiber and epoxy resin is 1:1. Hand la up method is employed for fabricating the samples and trimmed them under ASTM D 256 standards for experimentation. It is observed that the impact strength and hardness of composite is increased after utilizing the nano jute fiber composite than pure glass fiber epoxy composite.
