Abstract
Natural fibers are lignocellulosic and hollow in nature and having good mechanical, thermal and structural properties. In the present research endeavor, three types of natural fibers (namely Sisal, Hemp and Nettle fibers) are used as reinforcement in woven mat form to fabricate 4-ply laminate composites with epoxy resin as matrix using hand layup process. Atomic force microscopy (AFM) and scanning electron microscope (SEM) have been used to get the surface roughness of fiber, to study the fracture behavior of the developed composites and effect of inter surface bonding between fibers and matrix. Thermogravimetric analysis (TGA/DTA) has been performed to study the thermal behavior and intersurface bonding among matrix and fibers for the developed composites. The results revealed that along with the applied pressure and viscosity of the matrix, surface roughness of the fiber also plays a significant role in deciding the mechanical properties and natural fiber with high surface roughness exhibits better mechanical properties.
