Manufacturing the lightweight sandwich type engineered wood using Eucalyptus/epoxy wood core and teak veneer shins was the main objective of this research work. The in-house EGEBA base epoxy adhesive was formulated. Adding 10 g of DDS with respect to 100 g of TETA was mechanically desired. 1 phr of 4,4' oxybis(benzene sulfonyl hydrazide) or OBSH was quantified as optimal amount foaming agent for producing lightweight wood core with density of 0.7 g/ml. Single step manufacturing of lightweight sandwich structures engineered woods using teak/GFRP skins was explored. The enhancement of the sandwich structures properties was obtained. The performance of the manufactured wood with 4 layers of GFRP was successfully challenged with hardwood and teak.
