چکیده
In this research, creation of higher mechanical natural fiber mat composites was proposed. The hybrid mat with jute and glass mat was fabricated by needle punching system, in which jute mat was placed on glass mat. The ratio of jute and glass mat layers was set to be 1:0,1:1,1:2 and 2:1, respectively. The composites were fabricated by hand-lay up method with unsaturated polyester resin after needle punching process. Three-point bending test was carried out in order to obtain flexural behavior of different composites. The results show that flexural strength obtained for JF was approximately 37 MPa. Whereas similar flexural strength were achieved in JF/GF and JF/GF/GF, that exhibited about respective 61.7 % and 62.0 % higher than the values of JF. However, JF/JF/GF exhibited a lower value at around 38 MPa due to lager thickness of specimens than others. Finally, morphological analysis was carried out to observe fracture behavior using scanning electron microscope.

Comparative analysis of the mechanical and thermal properties of polyester hybrid composites reinforced by jute and glass fiber
This work describes the study to investigate and compare the mechanical and thermal properties of raw jute and glass fiber reinforced polyester hybrid composites. To improve the mechanical properties, jute fiber was hybridized with glass fiber. Polyester resin, jute and glass fibers were laminated in three weight ratios(77/23/0, 68/25/7 and 56/21/23) respectively to form composites. The tensile...

In the present work, Na+-montmorillonite nanoclay (Na-MMT) was functionalized using 3-aminopropyltrimethoxysilane (3-APTMS) as a coupling agent. The covalent functionalization of MMT was confirmed by Fourier-transform infrared spectroscopy (FT-IR). In the specimen fabrication stage, 5 wt% of pristine MMT or silane-functionalized MMT (f-MMT) were incorporated into an epoxy system and the resulta...
