Preparation of epoxy-glass composites with graphene and flyash filler Sarada Prasad Parida, Pankaj Charan Jena ⇑ Department of Production Engineering, Veer Surendra Sai University of Technology, Burla, Odisha, India article info Article history: Received 6 January 2020 Accepted 13 February 2020 Available online xxxx Keywords: Composite Filler Graphene Flyash Epoxy Glass abstract Generally the combination of two or more constituent materials forms Composite materials to meet the desired property. Most widely glass fiber reinforced polymeric composites (GFRPC) are used due to its easy availability and cheap cost. A set of various types of manufacturing methods are followed to prepare the composites. Hand layup technique is widely adopted one among them. In this process, a layer of resin is impringed over the fabric layer by a paint brush and toothed roller. To increase the mechanical strength of the GFRPC, nano materials are added to the resins as filler. In this work, Graphene and flyash is used as filler along with the epoxy and glass to prepare the test specimens. Graphene being a costly material, the possibility of the use of graphene at targeted layer along with flyash, most possibly at outer most layers and at core is explored. The functional gradation of composite plates of multiple layers are targeted and achieved. The preparation technique has been discussed elaborately. Ó 2020 Elsevier Ltd. All rights reserved.

Introduction Composite materials with glass fiber reinforcement are very common in daily to daily life use. Its properties like high strength, modulus, corrosion resistance, insulation are excellent. Glass fiber reinforced epoxy composite is a very common natural choice of composite, generally used in structural application. The use of glass fiber epoxy composite is very commonly used in automobile bod- ies, industrial furnishings, household and now days as furnishing materials used in decorative. Continual efforts have been given by the researchers from the beginning of the polymer composite development to enhance their properties according to the neces- sity and application. To enhance the thermo-mechanical proper- ties, filler material addition is a good choice (Figs. 1 and 2). The preparation methodology of composites is an age old tech- nique. Perhaps the making of straw reinforced mud walls in prepa- ration of huts in neolithic age was the first instance of manufacturing of composite. Day by day the optimized use and improved technologies in the modern age of science have increased the usability and broad application area. A number of method of manual and mechanized preparation method are avail- able. Looking to the literature a numerous study can be found. Comprehensive descriptions of the manufacturing techniques of composite materials have been presented in this regard [1–5]. Par- ida and Jena [6] have discussed a set of techniques generally adopted to prepare functionally graded material. Parida et al. [7] have analyzed the dynamic properties of the FGM beams in ther- mal environment. Saraswati et al. [8] have made a setup to prepare natural fiber reinforced composite dispersed by graphene and fly ash. They observed that the dispersed materials increase the mechanical strength like hardness, flexural, tensile and impact strength. Singh et al. [9] have developed FG pipe by centrifugal casting and characterizes their mechanical property. Jena et al. [10–13] have prepared epoxy glass composite and studied the dynamic properties in the presence of crack. They have prepared the SiC dispersed polymeric composites and studied their crack signatures from the modal responses [14]. Stankovich et al. [14] Presented preparation method of graphene polymer composite. Mohana et al. [15] have presented a comparision study on the use of graphenes and its derivatives to manufacture polymeric nano composites. Kinloch [1 1 6] have reviewed the preparation methodology and practical usuability of graphene dispersed com- posites. Yu et al. [17] have presented an introduction to prepartion technologies of graphene based glass fiber polymer composites. They also briefly described about the recent advances and the chal- lenges faced during the preparation. Borenstein et al. [18] have presented an extensive survey on the application of carbon based composites specially as super capacitors and electrodes. Papageor- giou et al. [19] have stated the effect of addition of dispersed https://doi.org/10.1016/j.matpr.2020.02.501 2214-7853/Ó 2020 Elsevier Ltd. All rights reserved.
