Abstract

Abstract: Polymer matrix composite materials have attracted the researchers over a period due to its superior specific strength compared to conventional materials. Bio based fibers started to emerge rapidly for industrial components, encompassing the technological/scientific aspects and the economic, environmental and social issues. Amongst the variety of bio-based fibers, Basalt fiber occupies a prominent position, due to its overall production and its unique chemistry-related features. It is derived from volcano rocks. UHMWPE having higher specific strength, non-reactive, chemically inert, and hence finds its applications in biomedical field. In the present investigation, UHMWPE fiber (plain woven fabric) along with the basalt fiber (plain woven fabric) are added as reinforcement to LY556 epoxy to bring in hybrid characteristics to the material and comparative studies are conducted with non-hybrid composites. Fabrication is carried out by hand lay-up technique. Mechanical tests such as hardness, tensile and flexural tests are conducted for the fabricated material. Density and water absorption behavior of the composites are also studied. Conventional hand layup method is used for fabrication of composites. From the results obtained, it is obvious that the flexural strength of hybrid composite is enhanced due to the hybridization with the addition of UHMWPE fabrics on the outermost layers in BFRP composites and augments its suitability in the use of engineering structural applications.
