Prakash, Ranga Vittal H. K., A. Thimmana Gouda Abstract: Cenosphere is a powder form material obtained by burning of coal in thermal plants. This industrial waste is ceramic rich, economically available and as filler material has the potential to improve properties of Composites. This work deals with the effect of cenosphere as filler material on mechanical properties of the Hemp/Glass Reinforced Epoxy Hybrid Composites. Industrial hemp fiber/fabric, which is produced by the bast of the hemp tree, is used along with Glass fibers in this hybrid composite with cenosphere as a filler material and epoxy as the matrix material. Hand layup technique is used to develop composite specimens with various weight fractions. Composite specimen prepared as per relevant ASTM standards were tested for their mechanical properties to establish the influence of cenosphere and glass fabrics in the laminates with Hemp fabrics. It has found that some of the properties of hybrid composite samples are significantly increased by the influence of filler material. This hybrid composite can be used as alternative material to plastics used in automobile mudguard.

INTRODUCTION Nowadays, researchers worldwide have focused on use of bio degradable, locally available and inexpensive natural fiber reinforced composites for different stream applications. Extensive studies on preparation and characterization of polymer matrix composite (PMC) replacing the synthetic fibers like Glass with natural fiber like abaca, banana[24], Bamboo[20], coir[4], flax, Hemp, Jute[21], Kenaf[30] , Sisal[28, 29], Pineapple have been carried out by several researchers [1-5,7,19]. Among these natural fibers, hemp being light weight & fast growing has a high potential due to its strength & other mechanical properties. In addition filler materials are used to improve certain mechanical properties to some extent and also reduce the material cost. One such filler material is cenosphere which is composed mainly of silica and alumina and has a high potential due to its light weight, low cost, & inertness [14, 15, 27].

Thimmana Gouda, Professor, RYMEC, Bellary, Karnataka. India. E-mail: atgoud@gmail.com Materials have extensive engineering application where strength to weight ratio, low cost and ease of fabrication are required[13].The main objective of the work is to investigate the mechanical properties of hemp fiber/fabric and Glass reinforced Hybrid Epoxy composites with cenosphere as a filler material and explore its application . Tensile, flexural, compression, impact & wear tests are carried out on composite samples with different weight fractions of hemp, glass fabrics, filler material cenosphere with epoxy as a matrix material. II. MATERIALS AND METHODOLOGY 2.1 Materials  Hemp fabrics- it is a bast fiber which is extracted from the hemp (Cannabis sativa) plant which is a source of extraordinarily tensile and durable fibers. Most of the hemp fibers reinforced composites used in automotive applications is mostly as interior components. Hemp supplied by lakshmi groups, Guntur is used in this work.  Glass fabrics- it is a synthetic material used as reinforcement material to increase the composite properties. Glass fiber supplied by suntech fibers, Bangalore, is used in the current work.  Matrix material Lepox L6 and K 12 hardener - Epoxy resins are a family of monomelic material that can be further reacted to form thermoset polymers,  Cenosphere it is a lightweight, inert, by-product of burning process of coal at power plants. The supplier is Cenosphere India pvt. Ltd, Kolkata. 2.2 Methodology 2.2.1 Fabrication of composites Hemp fabric and Glass reinforce Hybrid Epoxy composites with cenosphere as a filler material were prepared with hand lay-up technique for a size of 400 mm x 400 mm x3 mm. Matrix Lepox L6 with hardener K12 was mixed with 10:1 weight ratio. Table 1 gives the details of compositions of various samples fabricated by changing weight fractions and cured for the 24 hours.
