Mechanical Properties of Gamma-Irradiated Natural Fiber Reinforced Composites

Abstract

Today we are facing a great problem due to the synthetic compounds, as most of them are not environmentally friendly. Natural fibers are the fibers which are obtained from the nature and these fibers are environment friendly. So the use of natural fiber is increasing day by day in different sectors. But natural fiber has some limitations for widely use, one of them is the hydrophilic nature. So it cannot be widely used. That is why we need to incorporate them with low mechanical property synthetic compounds, widely known as composite materials. When we are using natural fiber with polymeric materials by forming composites, the fiber properties greatly influence the strength or mechanical properties. So researchers are trying to reduce this weakness of the natural fiber reinforced composite materials. One of the widely used methods for the improvement of tensile properties is the application of radiation (gamma and UV). The control use of gamma and UV-radiation increases the tensile properties in some extent for the use of materials in practical applications. The reason of this increment in tensile properties is the high energy radiation making crosslink among the molecules. In all the respect of fiber reinforced composite highest tensile properties are observed at a certain dose of gamma and UV-radiation.

PP-coir Composites (PPCC): Fabrication and Study of Flexural Properties

“…It also shows that up to 20% the strength is higher than that of pure PP. Similar effect was found by Rashed and Rizvi [5], Shabname Ele [6], Bipasha Bose [3]. apparent that elongation decreases very slightly with the increasing fiber content.…”

“…The use of natural fibers, derived from annually renewable source, as reinforcing fibers in both thermoplastic and thermosetting matrix composites provides positive benefits with respect to ultimate disposability and raw material utilization [1][2][3][4][5][6]. Coir fiber has received considerable attention for its diversified use both in academic and industrial research.…”

“…Biodegradable plastics such as cellulose-based thermoplastics, aliphatic polyester etc. have attracted much attention in recent years from the point of view of environmental protection [2,3] . Natural fibers such as jute, coir, palm, banana etc.…”

Characterization of Chemical-Treated and Gamma Irradiated Pineapple Leaf Fabric/Epoxy Composites: Surface Structure and Physico-Mechanical Properties

“…With the help of several chemical treatments and gamma radiation, the hydrophilicity of PALF fibers can be changed and reduced which increase the fiber/matrix adhesion of the composite materials resulting in better composite quality and properties. Unsaturated polyester and epoxy are used as thermoset polymer and found to be the potential matrix materials for PALF fibers [13,20]. Now-a-days, epoxy resins are used as a thermoset polymer for various engineering applications.…”

Preparation and Characterization of Acacia Catechu Film: Effect of Monomer (HEMA) and UV Radiation

“…The hazardous effects of handling the radiation source are relatively less in case of UV radiation than the gamma radiation. These are the main reasons for selecting UV radiation sources for the betterment of mechanical properties of prepared materials [7][8][9][10][11]. Monomer treatment is one of the best methods for the improvement of the properties of the composite materials [12][13][14].…”
