Surface modification and micromechanical properties of jute fiber mat reinforced polypropylene composites

چکیده
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.

Biocomposites developed using water-plasticized wheat gluten as matrix and jute fibers as reinforcement
Biocomposites developed from wheat gluten using water without any chemicals as plasticizer and jute fibers as reinforcement have much better flexural and tensile properties than similar polypropylene composites reinforced with jute fibers. Wheat gluten is an inexpensive and abundant co-product derived from renewable resources and is biodegradable but non-thermoplastic. Previous attempts at deve...
