Effect of silica nanoparticles loading on mechanical thermal free vibration and hydrostatic pressure response of filament wound basalt epoxy and e glass epoxy composite tubes

Abstract

The Fiber Reinforced Polymer (FRP) composite tubes are subjected newlineto pressure, vibration, mechanical and thermal load during their service. newlineAssessing the ability of the pipes to withstand these loads is vital in the newlineselection, design and functionality of the pipes. In this study, the mechanical newlineproperties, thermal properties, vibrational behavior and pressure withstanding newlinecapacity of different weight percentages (0, 0.5, 1 and 1.5) of silica newlinenanoparticles dispersed in FRP composite tubes such as E-glass/epoxy and newlinebasalt/epoxy were studied. newlineThe mechanical and thermal performance studies of FRP newlinenanocomposites containing silica particles are limited, particularly, the newlinethermal properties of basalt/epoxy/silica nanocomposites at elevated newlinetemperatures are not enough and not well understood. Therefore, the present newlinestudy aims at investigating the mechanical and thermal behaviour of various newlineamounts of silica nanoparticles dispersed in the E-glass/epoxy and newlinebasalt/epoxy composites. The mechanical properties were estimated by newlinecarrying out the following tests tensile, flexural and impact studies. The newlinethermal properties were evaluated by using four different instruments newlinenamely dynamic mechanical analyser, differential scanning calorimetry, newlinethermogravimetric analyser and heat deflection temperature. Einstein and newlineGuth models were used to obtain the theoretical flexural and storage modulus newlineof epoxy/silica nanocomposites corresponding to different particle volume newlinefractions and a comparison was made between theoretical and experimental newlinevalues. A good correlation was obtained between them. newline
