Hybrid composites are fabricated by the combination of two or more fibers using a single matrix. It can be fabricated either with all of its constituents as natural fibers or with one or more constituents belonging to artificial fiber. The stacking sequence of the fibers in a hybrid composite can be altered resulting in a varying mechanical properties. In the present study the MWCNT filled banana-jute-flax fiber reinforced composites are investigated for its mechanical behavior by varying the stacking sequence of the fiber layers and weight % of Multi-Walled Carbon Nano Tube (MWCNT). A Modified resin was prepared by adding MWCNT in the epoxy resin using ultrasonic probe sonicator and a hybrid composite is fabricated with it by using compression moulding processes. The mechanical properties are evaluated as per the ASTM standards. The incorporating of MWCNT and the stacking sequence of fiber layers shows the greater impact on the mechanical properties. The composites of jute fibers at the extremities (JBFBFBFJ) exhibiting the enhancement of tensile, compressive and hardness properties than the flax fiber at the extremities (FBJBJBJF) and it could be used in various automobile applications. Microstructure of the samples are investigated by Scanning Electron Microscope (SEM)with Energy dispersive X-ray (EDS). The results indicate that increasing the weight % of MWCNT and varying the stacking sequence of fibers improves the mechanical properties of hybrid natural fiber composites. 相似文献

Composite reinforcement is defined as a technique to improve the engineering characteristics of composite and a fiber reinforced composite (FRC) is a composite material consisting of a polymer matrix imbedded with high-strength fibers, synthetic fibers or natural fibers. Natural fibers have recently become attractive to researchers, engineers, and scientists as an alternative reinforcement for FRCs. Nanocomposite shows considerable applications in different fields because of larger surface area, and greater aspect ratio, with fascinating properties. Being environmentally friendly, applications of nanocomposites offer new technology and business opportunities for several sectors, such as aerospace, automotive, electronics, and biotechnology industries. Hybrid bio-based composites that exploit the synergy between natural fibers in a nanoreinforced bio-based polymer can lead to improved properties along with maintaining environmental appeal. This review article intended to investigate natural fiber/nanofiller-based hybrid composite with specific concern to their physical and mechanical properties. 相似文献

Effect of Curing Temperature on Mechanical Properties of Natural Fiber Reinforced Polymer Composites
Nowadays, growing environmental concerns have led many researchers to work in the area of natural fiber reinforced polymer composites. In this work, jute fiber has been used as reinforcement and epoxy as matrix material to develop partially biodegradable green composite with the help of hand layup followed by compression molding technique. The effect of curing temperature ranging from 80°C to 130°C on different samples was investigated for various mechanical properties. Results obtained from the various tests indicate that with increase in curing temperature, impact strength decreases, but tensile and flexural strength increases and decreases thereafter attaining the maximum value at 100°C between aforementioned temperature range. The trend obtained for mechanical properties is further justified through the study of morphology with scanning electron microscopy, and optimum curing temperature has been suggested. 相似文献

This work was concerned with the development of polyurethane (PU) composites reinforced with cellulose fibers attained from sugarcane straw. For the obtainment of cellulose, sugarcane straw was pretreated and delignified. For the production of the PU, the polyol (castor oil) to diisocyanate mass ratio was 1.5:1.0. Reinforcement of the matrix was done, changing the concentration of cellulose fibers (5%, 10%, 15%, and 20% w/w). The efficiency on the obtainment of cellulose fibers was verified by chemical characterization and the fibers morphological aspects by scanning electron microscopy. The influence of fibers content in the composites was studied by thermal analyses, tensile and moisture absorption tests. 相似文献
