Effect of nano-filler content and fiber treatment on the characteristics of gamma-irradiated rice husk-epoxy particleboard composites

الملخص EN

In this study, both untreated and treated rice husk f؛Rece y,؛e؟po^y r^i,n to prepare particleboard composites.

The effect of different ratios of nanoclay na؛؛ Accepted 30“ Jan 2019 w^h 15“% and 20% (by the weight of the polymer) on the physicomechanical properties of the ه/“10 ؛%5 'e an؛ccep prepared particleboard composites is investigated.

The results show that the flexural, and impact strengths as a function of mechanical properties getting better with increasing nanoclay content up to While the addition of nanoclay to the samples decreases the water absorption percentage.

This ه/“10 decrease is almost constant with nanoclay (%).

In addition, the effect of different doses of gamma-irradiation on the properties of both untreated and treated rice husk-epoxy particleboard composites that containing 10% of nanoclay is also discussed.

The results show that the irradiated specimens at a dose of 10 kGy achieved a good enhancement in mechanical properties whereas the water absorption percentage as a physical property decreases at a dose of 10 kGy and starts to increase with increasing .gamma irradiation doses.

TGA, and SEM are carried out to confirm the data obtained
