THERMAL CONDUCTIVITY ENHANCEMENT OF SILICON INSERTED HYBRID COMPOSITE MATERIALS

In this investigation thermal conductivity test was carried out to the prepared specimen of silicon inserted hybrid composite material (on silicon inserted glass –fiber chop strand and other silicon inserted glass –fiber 900woven). The specimens were prepared by hand layup followed by compression molding method. The apparatus consist of two copper plates and one specimen together clamped on both sides using bolts and nuts. On one side of the copper plate a heater is fitted. End losses from the plates are minimized by providing thick insulation all around to ensure unidirectional heat flow. A dimmer stat is provided for varying the input to the heater and measurements of input is carried out by Voltmeter. Thermocouples are bounded in mica are embedded between the interface of the copper materials and the specimen of silicon inserted hybrid composite material, to read the temperature at the surface

A REVIEW ON THERMAL PROPERTIES OF GLASS FIBRE REINFORCED HYBRID POLYMER COMPOSITE MATERIALS

Hybrid Polymer Composites offer new solutions to materials problems; they are currently the focus of research and development areas in all over world. In many common and advanced engineering applications, polymers and their hybrid composites are emerging as variable alternatives to metals and their alloys. Due to different thermal conditions and mechanical loading situations, hybrid composite materials need to be tested intensively. The hybrid composite materials are exposed under different low temperatures and high temperatures at environmental conditions will gives polymeric matrix hybrid composites are susceptible to degradation and material properties changes. Carbon fibre composites are widely used as structural reinforcement materials of buildings, replacing reinforcing bars or concrete which should have excellent mechanical and thermal properties. Hybrid polymer composites with different filler materials will give different thermal property values for variable temperature conditions. This paper presents reviewon thermal properties fibre reinforced hybrid composite materials and came to know that still an abundant scope to do research on study of thermal properties of composite materials by using Silicon, Aluminium oxides, Carbon and Graphite as a filler material of combination of glass fibre and natural fibres. This review study shows that the effect of thermal properties on fibre reinforced hybrid composite materials and hybridization can improve thermal properties
