Abstract
Present study demonstrates the fabrication of a series of sandwich composite structures (SCs) through alternate bonding of poplar wood plies (PWPs) in 4-ply arrangement with clay/epoxy adhesives. The process of adhesive bonding was executed in the presence of various proportions of bentonite (BT: 0.0, 1.0, 2.0 & 3.0 wt%) into commercially available epoxy resin (ER, CY-230) followed by curing with a solid phase hardener (HT-972) under compression of 10 kg/cm2 at 25 ± 1 °C. Physical behavior of SCs was investigated in terms of density (g cm−3), direct current conductivity (μS/cm) and hydrophobicity test of SCs. Scanning electron microscopy reveals distribution of bentonite into porous matrix of PWPs. With wt% of BT ranging 0.0 to 3.0, the density (g cm−3) and direct current (DC) conductivity (μS/cm) of SCs were enhanced ranging 0.47–0.55 and 2.3–2.82 with simultaneous control over their hydrophobicity under immersion in water over 24 h.
