| Abstract | The resorcinol-urea-formaldehyde-casein (RSUFC) resin was synthesized by olycondensation reaction of urea, casein and formaldehyde in the presence of varying proportion of resorcinol under alkaline condition. All the prepared resins were haracterized by free-formaldehyde content, free-phenol content, viscosity easurements and infrared spectroscopy (IR). The resin samples were cured isothermally at 120oC using two different curing agents, p-toluene sulphonic acid (PTS) and hexamine and also by differential scanning calorimetry on dynamic run to understand the curing behaviour of novel resin samples. The cured resins were characterized by IR and thermogravimetric analysis. The resin samples were employed for the fabrication of glass fibre and jute fibre reinforced composites, respectively by maintaining 2:3 and 3:2 proportion of resin: reinforcement.Thus prepared composites were tested for their mechanical properties and resistance towards various chemicals. |
