Arun G., . and Anuj K., . and Sharma K. V., . (2014) Reinforcement effect of multi walled carbon nanotubes MWCNT and alumina AL2O3 nanoparticles on the properties of medium density fiberboard MDF. [Proceedings Paper]

Various methods such as steam injection long pressing time and high platen temperatures were used to increase the heat transfer inside the wood fibre mat for improving the curing rate of thermoset resin. In this work high conductive multiwalled carbon nanotubes and alumina nanoparticles were employed to enhance the heat transfer properties of wood fibres. The effects of alumina nanoparticles and multiwalled carbon nanotubes on the physical and mechanical properties of medium density fibreboard were also investigated. The core layer temperature profile was recorded using K-type thermocouples during hot-pressing process of fibreboard. The results showed that the heat transfer properties improved and alumina nanoparticles had beneficial effects on the mechanical properties and dimensional stability of the fibreboards. While MWCNT increases the internal bonding at a statistically significant level P 0.05 the thickness swelling showed the improving trend and water absorption show negative trend the difference was not statistically significant.

Abstract

Various methods such as steam injection long pressing time and high platen temperatures were used to increase the heat transfer inside the wood fibre mat for improving the curing rate of thermoset resin. In this work high conductive multiwalled carbon nanotubes and alumina nanoparticles were employed to enhance the heat transfer properties of wood fibres. The effects of alumina nanoparticles and multiwalled carbon nanotubes on the physical and mechanical properties of medium density fibreboard were also investigated. The core layer temperature profile was recorded using K-type thermocouples during hot-pressing process of fibreboard. The results showed that the heat transfer properties improved and alumina nanoparticles had beneficial effects on the mechanical properties and dimensional stability of the fibreboards. While MWCNT increases the internal bonding at a statistically significant level P 0.05 the thickness swelling showed the improving trend and water absorption show negative trend the difference was not statistically significant.
