Hybrid polymer composite material offers the designer to obtain the required properties in a controlled considerable extent by the choice of fibers and matrix. The properties are tailored in the material by selecting different kinds of fibre incorporated in the same resin matrix. In this paper, the thermal properties of GFRP, CFRP, and Carbon and Glass fibers reinforced epoxy hybrid composite will be studied. The composites using are all uni- directional. The compression moulding technique will be adopted for the fabrication of hybrid composite materials. The thermal properties such as Glass transition temperature, Thermal conductivity, Specific heat capacity are calculated using Dynamic mechanical Analysis (DMA), Differential scanning Calorimetry (DSC), Thermo gravimetric analysis (TGA) respectively. Key words: Hybrid polymer Composites, fibers, thermal properties, compression moulding technique. Cite this Article: Bhasker Bommara, Dr. M. Devaiah, P. Laxmi Reddy, M.

INTRODUCTIONComposites are one of the most advanced and adaptable engineering materials known to men.Progresses in the field of materials science and technology have given birth to these fascinatingand wonderful materials. A composite material can provide superior and unique mechanicaland physical properties because it combines the most desirable properties of its constituentswhile suppressing their least desirable properties. When considering high end engineeringapplications, composites are to be made lightweight and strong so as to improve theperformance of the application. The in plane properties like tensile strength and stiffness of http://www.iaeme.com/IJMET/index.asp 1055 editor@iaeme.com Thermal Characterization of Fiber Reinforced Polymer Composites and Hybrid Compositesfiber reinforced composites are known to be high. But fiber reinforced composites performspoorly when under in plane compression or when through thickness properties are considered.At present composite materials play a key role in aerospace industry, automobile industry andother engineering applications as they exhibit outstanding Strength to weight and modulus toweight ratio. Whereas thermo-mechanical properties like storage modulus, loss factor and glasstransition temperature of fiber reinforced composite is not up to the mark. High performancerigid composites made from glass, graphite, Kevlar, and boron or silicon carbide fibers inpolymeric matrices have been studied extensively because of their application in aerospace andspace vehicle technology. Since the application of composites spread into almost allengineering applications, it became a necessity to improve their thermo-mechanical properties.The properties of these composite materials can be further enhanced by integrating both CFRPand GFRP composites in a particular orientation and mixing ratio. Several fundamentalconstitutive relations have been developed throughout the later part of 20th century which helpsin predicting the mechanical properties of the above mentioned materials. These relations canbe of consequence to the composition of the material before its preparation. In the recent yearconsiderable amount of research has been done on the composites for improvement in thermo-mechanical properties of the composites.Lei Zhang et al. [1],studied thermal response of theGFRP multi cellular specimens assembled with different fire resistant panels namely glassmagnesium (GM) board, gypsum plaster (GP) board and light weight calcium silicate (CS)board. He measured and comparatively analyzed, in association with the damage patternsobserved. It was found that the fire resistant panels effectively mitigated the temperatureprogressions developed in the GFRP components, thereby improving the fire insulationperformance of those structural assemblies. The GM board provided the best fire insulationperformance, with the highest temperature at the outer face of the upper GFRP flat panel beingless than 1200C after 90 minutes of fire exposure. Further, the effects of cavities and end closureconfigurations of the multicellular assemblies on the heat transfer were evaluated andhighlighted.N Dubary et al. [2], investigated the impact damage tolerance of hybrid carbon andglass fibers woven-ply reinforced Poly Ether Ether Ketone (PEEK) thermoplastic (TP)laminates obtained by consolidation process is investigated. Service temperature being one ofthe most important parameters to screen TP or thermosetting matrix for aeronautical purposes,impact testing at room temperature (RT) and near the glass transition temperature (TG) hasbeen conducted. From the results, it turns out that tempe ...
