world in all accepts as a replacement, by using the alternative materials. These alternative composite materials are more versatile than metals and can be tailored to meet performance needs and complex design. Long life and its excellent fatigue-, impact-, environmental-resistance and reduced maintenance requirements helping in replacing the conventional materials. Best in mechanical properties against high tensile strength , high strength to weight ratio and low thermal expansion. The Natural fiber composites such as Sisal and jute polymer composites has shown good properties such as high specific strength, lightweight and biodegradability. Sisal and jute Reinforced Polymers are showing huge applications. In this study, Sisal–Jute reinforced epoxy composites are Elaborated and their mechanical properties like flexural strength, impact strength and tensile strength are calculated. The detailed structures like internal cracks and fractured surfaces are determined by using Scanning Electron Microscope (SEM). The results obtained shows that the Sisal and jute polymer composites can be used as an alternate material for synthetic fiber reinforced polymer composites
Common low density fibres are manufactured from lighter materials especially those based on elements with low atomic number (e.g., H, Be, B, C, N, O, Al, Si, etc.). The crosssection of a fibre may be circular, for example as in the cases of glass, boron and Kevlar fibres, but some fibres may have regular prismatic cross-sections (e.g., whiskers) or arbitrary cross-sections. Natural fibers are chosen as reinforcement because they have very good tool wear reducing properties, while processing, the system of steps and serving as alternatives for artificial fiber composites in the increasing global energy crisis and ecological risks. In the current study the mechanical properties of jute and Sisal reinforced composite materials is studied. The jute and sisal reinforced composite materials are manufactured by hand layup method and compressed using Compression moulding machine. The properties such as tensile, flexural and impact are studied and presented in detail.
Key Words: Composite materials, Sisal fiber, jute fiber.
2. Experimental details 1. INTRODUCTION 2.1 Materials The Fiber reinforced polymer (FRP) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinylester, or polyester thermosetting plastic, though phenol formaldehyde resins.
Jute fibres are composed primarily of the plant materials cellulose (major component of plant fibre) and lignin (major components of wood fibre). The fibres can be extracted by either biological or chemical retting. The fibers are off-white to brown, and 1–4 metres (3–13 feet) long. Jute is also called the golden fiber for its color and high cash value Jute fibers were bast Fibers extracted out of plants of the genus Corchorus that grow mainly in warm and moist regions. The fibers of this study are extracted with a mechanical process. Sisalis derived from the leaves of the plant. It is usually obtained by machine decortications in which the leaf is crushed between rollers and then mechanically scraped. The fibre is then washed and dried by mechanical or natural
Fibres constitute the main bulk of reinforcements that are used in making structural composites. A fibre is defined as a material that has the minimum 1/d ratio equal to 10:1, where 1 is the length of the fibre and d is its minimum lateral dimension. The lateral dimension d (which is the diameter in the case of a circular fibre) is assumed to be less than 254 m. The diameter of fibres used in structural composites
