Studies On Epoxy Clay Nano Composites For Pressure Pad Application And Epoxy Pottery Clay Adhesive For Canister Application

Abstract

Epoxy0 resins0 are0 widely0 used0 in0 fibre-reinforced0 composites0 due0 to0 their0 superior0 newlinethermal,0 mechanical,0 and0 electrical0 properties.0 Depending0 on0 the0 chemical0 compositions0 newlineand0 curing0 kinetics,0 it0 is0 possible0 to0 vary0 their0 mechanical0 properties0 ranging0 from0 newlineextreme0 flexibility0 to0 high0 strength0 and0 hardness,0 and0 physical0 properties0 such0 as0 newlineadhesive0 strength,0 chemical0 resistance,0 heat0 resistance0 and0 electrical0 resistance.0 The0 newlinewidespread0 use0 of0 the0 epoxy0 thermosets,0 however,0 is0 limited0 in0 many0 high-performance0 newlineapplications0 because0 of0 their0 inherent0 brittleness,0 delamination0 and0 fracture0 toughness0 newlinelimitations.0 The0 development0 of0 improved0 high-performance0 composites0 based0 on0 newlinethermosetting0 polymers0 can0 only0 be0 achieved0 by0 simultaneously0 improving0 resin,0 fibre0 newlineand0 interface0 properties. newlineThe main objective of this work is to characterize the Epolam 2022 epoxy mixed with newlinenanoclay and then give a detailed comparison of the changes in the properties of the modified newlineepoxy. Both the neat epoxy and the nano clay mixed epoxy are tested for their behaviour newlineunder mechanical, tribological and environmental conditions. The tests reveal that mixing the newlinenanoclay improves the properties of the epoxy under consideration significantly. newlineAnother objective of this research work is to find an improved and low cost adhesive which newlinehas a wide range of applications. Araldite Epoxy AW106 and Loctite Superior 40025 are newlinecompared where the Araldite epoxy was mixed with pottery clay to improve its properties. newlineComparison was done on the basis of shear strength and vibrational characteristics. It was newlinefound that mixing pottery clay with the Araldite epoxy showed an overall improvement in its newlineproperties when compared to the Loctite Superior newline
