In this study, the hybridization effect on the mechanical properties of the natural fiber reinforced composites was investigated. For this purpose, glass fibers in different ratios of 2.5, 5 and 10 wt% were added in the polymer composites with cotton fibers at the ratios of 12.5 and 25 wt%. In order to have better interfacial bonding and increase the effectiveness of glass fiber on the mechanical properties, maleic anhydride coupling agent was added in the hybrid composite structures. At the end of the study, the best ratios of maleic anhydride, cotton and glass fiber for this kind composites were explored with respect to the economical and mechanical concerns. This study suggests that hybridization can be considered as most promising way to improve the mechanical properties for this novel composite materials.

PET/60HBA-MWNTs Liquid Crystalline Polyester (LCP) composite was synthesis by melting polymerization process with a novel method of reacting in acetic anhydride solution. FTIR, XRD, POM, TGA and mechanical properties tests were applied for the characterization of modification of nanotube, crystallization property, thermal and mechanical properties. The results indicate that thermal and mechanical properties of LCP polyester are all enhanced with 0.3wt% MWNTs addition. The degradation temperature (Td) increased for 8°C and the modules, strength and breaking elongation are increased by 39.0%, 62.3% and 46.4% respectively.

Due to desirable properties and its role of natural and manmade fibers reinforced composite materials are growing in a faster rate in the field of engineering and technology. Now-a-days the treated natural composites are serves better in terms of corrosive resistance, and other desirable properties when compared to the traditional materials. The main aim of this experimental study is to fabricate and investigate the mechanical properties such as tensile strengths, flexural strengths and impact strengths of NaOH treated and hemp-banana-glass fibers reinforced hybrid composites. From the experimental results, it has been noted that the treated hemp-banana-glass fibers reinforced hybrid epoxy composites exhibited superior properties and used as an alternate material for synthetic fiber reinforced composite materials. Morphological studies are carried out to analyze the interfacial characteristics, internal structures, fiber failure mode and fractured surfaces by using scanning electron microscopy (SEM) analysis.

The application of natural fiber-reinforced composites is gaining interest in the automotive, aerospace, construction, and marine fields due to its advantages of being environmentally friendly and lightweight, having a low cost, and having a lower energy consumption during production. The incorporation of natural fibers with glass fiber hybrid composites may lead to some engineering and industrial applications. In this study, abaca/glass fiber composites were prepared using the vacuum-assisted resin transfer method (VARTM). The effect of different lamination stacking sequences of abaca–glass fibers on the tensile, flexural, and impact properties was evaluated. The morphological failure behavior of the fractured-tensile property was evaluated by 3D X-ray Computed Tomography and Scanning Electron Microscopy (SEM). The results of mechanical properties were mainly dependent on the volume fraction of abaca fibers, glass fibers, and the arrangement of stacking sequences in the laminates. The higher volume fraction of abaca fiber resulted in a decrease in mechanical properties causing fiber fracture, resin cracking, and fiber pullout due to poor bonding between the fibers and the matrix. The addition of glass woven roving in the composites increased the mechanical properties despite the occurrence of severe delamination between the abaca–strand mat glass fiber.


: In general the natural fibers are taken out from the sources of animals and plants. In recent days the natural fibers play an important role in engineering applications like automotive, aerospace and marine industries due to abundant availability, less in cost and zero percentage environment harmless in nature. In this paper the investigation of various mechanical properties of hybrid reinforced composite (Palm fiber Basalt S-glass fiber) is been done on the fabricated samples. The different mechanical property includes tensile, hardness and impact tests etc... The fabrication comprises three layers of Palm and Basalt fibers outer laminated by two layers of S-glass fibers using injection molding method. From the various testing and investigation against the test sample it is been concluded that the fibers in the hybrid set took a major role in determining the important mechanical properties. Thus the fibers present in the hybrid composite increases the strength, stiffness and weight ratio of the composite materials. The various forms and structural analysis of the hybrid composite material are processed by using scanning electron microscope for attaining the better results and application basis

Glass/epoxy (G-E) products are widely used in numerous industries nowadays. This is due to favorable characteristics of these products including low cost, ease of manufacturing, good mechanical properties, and lightweight. The mechanical properties of G-E composites can be enhanced through mixing with natural reinforcement materials. In this work, we investigate the use of date seeds (DSs) as a reinforcement material for G-E composites. A DS filler has been added to G-E hybrid composites as a powder by applying a semiautomatic technique. Glass fibers reinforced with angle-ply ([±45]4) were considered as commonly used G-E composites. G-E reinforced DS composites were analyzed using various mechanical characteristics such as mica-hardness, tensile strength, and impact strength. Effects of the DS filler on the wear volume loss (VL) were investigated at different parameter settings. This loss was analyzed using the traditional Taguchi method and the nontraditional flower pollination algorithm to obtain optimal parameters. Surface inspection using a scanning electron microscope and Fourier-transform infrared (FTIR) was conducted. The results revealed that the addition of a 10% DS reinforcement to G-E composites enhanced the wear resistance and increased toughness and hardness. Finally, G-E-DS composite optimization was carried out by minimizing the wear VL. This resulted in an optimum DS reinforcement of 10% at a normal load of 10 N, an abrasive size of 1200 mesh, and an abrading distance of 420 m. Deviations from this reinforcement ratio degrade the mechanical properties of the G-E-DS composite. Moreover, the significant factors are the abrasive size, reinforcement material wt%, normal load, and abrading distance. The contributions of these factors are 30.6%, 15.5%, 11.8%, and 10%, respectively. FTIR results indicate that a chemical interaction has occurred between G-E and the organic DS. These experimental results are in good agreement with the theoretical ones.
