“…It can be also seen that the Weibull modulus values for jute fibers are much lower compared to synthetic fiber such as carbon fiber [20], which indicates the non-homogeneous nature of natural fibers which in turn is due to the predominance of defects within their structures. Similar results were reported earlier for other natural fibers by some authors [21][22][23]. The tensile strength of fibers increases obviously after treatment of NaOH.…”

Abstract.A new treating method using sodium hydroxide (NaOH) and Maleic anhydride-grafted polypropylene (MPP) emulsion was introduced to treat jute fiber mat in order to enhance the performance of jute/polypropylene (PP) composite prepared by film stacking method. The surface modifications of jute fiber mat have been found to be very effective in improving the fiber-matrix adhesion. It was shown that treatments changed not only the surface topography but also the distribution of diameter and strength for the jute fibers, which was analyzed by using a two-parameter Weibull distribution model. Consequently, the interfacial shear strength, flexural and tensile strength of the composites all increased, but the impact strength decreased slightly. These results have demonstrated a new approach to use natural materials to enhance the mechanical performances of composites.

“…Among the natural fibers, that extracted from the stem of the jute plant (Corchorus capsularis) is worldwide cultivated and has been extensively investigated in this decade as composite reinforcement [26][27][28][29][30][31][32] . The jute fiber was reported 20 to present density, 1.30-1.45 g/cm 3 and tensile strength, 393-800 MPa, convenient to replace synthetic fibers in polymer composites.…”

“…In contrast with the hemicellulose content, the cellulose content needs to be retained as much as possible during the SHS treatment because it is important for the crystalline structure to the fibers. Basically, a higher cellulose content leads to higher stiffness, which explains why the cellulose content and the microfibril angle have a major influence on the mechanical properties of composites (Doan et al 2006). As shown in Fig.…”

Optimization of Superheated Steam Treatment to Improve Surface Modification of Oil Palm Biomass Fiber

et al. 2016

Superheated steam (SHS) pretreatment is an effective method for hemicellulose removal from oil palm biomass (OPB) fiber, which leads to the surface modification of the fiber. However, the current SHS pretreatment is conducted at a high temperature and has a long retention time, which causes the removal of cellulose, which is an important component for biocomposite production. This study was conducted to optimize the SHS treatment temperature and retention time so that hemicellulose but not cellulose was removed. Three types of OPB fibers were used: oil palm mesocarp fiber (OPMF), oil palm empty fruit bunch (OPEFB), and oil palm frond (OPF). The chemical composition data was analyzed using a type of response surface methodology (RSM), i.e., central composite design (CCD). The optimal SHS treatment temperature and retention time were 265 °C/5 min, 280 °C/5 min, and 300 °C/9 min for OPMF, OPEFB, and OPF, respectively. The removal of hemicellulose at these temperatures was in the range of 60% to 70%, while the cellulose degradation was maintained below 5%. Statistical analysis showed that the optimal SHS treatment time can be shortened to 5 min to 9 min, which is 18 to 20 times shorter than previously reported methods.
