Fabrication and Investigation of Nano Silicon Carbide Particulate Reinforced Polyester Matrix Composite

Abstract

In this investigation, the ceramic material SiC is used as newlinereinforcement owing to its unique character such as hardness, thermal newlineconductivity and strength. This has paved the way for using it in the newlinemaking of polyester nano composite (nPMC) with aforementioned newlineproperties. Fabrication and characterization of Nano-composite sheet is newlinecarried out using a weight ratio of 30% SiC nano particulates, so as to newlineunderstand the molecular structure and mechanical behaviour under newlineexternal load. The synthetic procedure and characterization used in this newlinestudy has made it possible to obtain SiC nano particles reinforced newlinepolyester nano-composite (nPMC) with good thermal strength and newlinechemical homogeneity over the traditional composite. The higher tensile newlinestrength of silicon carbide particulates with smaller size increases when newlineplaced under heat. newline SiC particles produced by top down approach which is derived from newlinequartz ore collected in bank of Ponnaiyar river and hillside area of Tamil newlineNadu, India. Their physical and chemical phenomena are discussed in newlinefocus with the influence of the size effect. The instruments such as newlineTransmission, Scanning Electron Microscope (SEM andTEM), FT-IR newlineapparatus, particle size analyzer (PSA) and thermal conductivity test newlineapparatus are used to investigate the samples and explained by the way it newlinehas been used. newline The nano size of the particle influences homogeneous in structure newlineof nPMC. It reduces stress concentration, fracture failure and not lean to newlinematerial failure during service whereas the micro particulate composite is newlinegreater compressive strength and less tensile strength. The different size newlineand percentage of SiC particulate polyester composite specimen is made newlineto test and understand the mechanical strength as per ASTM standard. newlineHowever, nano silicon carbide particulate developed from indigenous newlinesources is used in composite which is highly used in novel application newlinesuch as body of electronic gadgets, aerospace, medical, automotive and newlineindustry. newline newline newline
