| dc.description.abstract | A series of acrylic hydrazide (AH) cured epoxy were synthesized at varying concentration of acrylic hydrazide ranging 11.5:1 to 6.14:1 (epoxy: acrylic hydrazide, v/v %) through in-situ polymerization method. In present investigation it has been observed that density of AH cured epoxy composite is slightly higher compared to hardener HY951 cured epoxy composite at same concentration of curing agent. Wear behavior has been tested and it is observed that acrylic hydrazide cured epoxy 9:1 & 7.33:1 (epoxy: acrylic hydrazide, v/v %) have lower wear rate compared to hardener HY951 cured epoxy. Mechanical and thermal property of the developed composite has been determined and results were compared with composite made from commercially available hardener HY951 cured epoxy CY230. It is found that composite developed with acrylic hydrazide cured epoxy CY230 of ratio 9:1 & 7.33:1 have higher tensile strength, compressive strength, impact strength and hardness compared to HY951 cured epoxy composite. With reference to its material fringe value, it can also be used as photo-elastic material. For spectral characterization UV-VIS spectra and FTIR tests were conducted to study the stabilization of the developed composites. DTA-DTG-TG tests were conducted to study the thermal properties of the composites. Results are compared with HY951 cured epoxy composite. Properties are found to be superior than the composite made from HY951 cured CY230. | en_US |
