Physical and mechanical properties of ghora neem (Melia azedarach) plywood

Abstract

This paper gives the results of ghora neem (Melia azedarach) plywood for assessing it as an alternative raw material for plywood industries. Five ply ghora neem plywood of 2400 mm×1200 mm×12 mm size was manufactured using urea formaldehyde adhesive. The important physical and mechanical properties were examined for assessing its quality. The results of physical and mechanical properties of ghora neem plywood were compared with the data obtained with existing market available plywood manufactured with shimul (Bombax ceiba). The density of ghora neem plywood and shimul plywood was 541.00 and 499.80 kg/m 3 respectively. The MOR was 58.33 N/mm 2 for ghora neem plywood while it was 32.52 N/mm 2 for the shimul plywood. The MOE was found for ghora neem plywood 3950.01 N/mm 2 and on the other hand, the shimul plywood showed 3224.15 N/mm 2 . The ghora neem plywood showed better performance for both physical and mechanical properties and it also follows the standard.

Variation in intrinsic wood properties of Melia azedarach L. planted in northern Vietnam

“…The flowers are small and fragrant, with five pale purple or lilac petals, growing in clusters. The fruit is a drupe, marble-sized, light yellow at maturity, hanging on the tree all winter, and gradually becoming wrinkled and almost white [3].…”

Particleboard from coir pith

“…al., 2014;Islam et al, 2014;Das et al, 2015). Investigation was also carried out to find out the properties of plywood made by ghora neem and raj koroi (Rahman et al 2013;Rahman et al 2014). According to a report from Food and Agricultural Organization (FAO) of the United Nations, the worldwide demand of particleboard panels was 56.2 Mm 3 in 1998 (Youngquist and Hamilton, 2000).…”
