EFFECTS OF HOT OIL TREATMENT ON PHYSICAL AND MECHANICAL OF OF PHILIPPINE BAMBOO

Abstract

MANALO RD & ACDA MN. 2009. Effects of hot oil treatment on physical and mechanical properties of three species of Philippine bamboo. The effects of hot oil treatment on physical and mechanical properties of three species of Philippine bamboo, viz. Bambusa blumeana, B. vulgaris and Dendrocalamus asper were investigated after exposure to virgin coconut oil at 160 to 200 °C for 30 to 120 min. The results showed improvement in water absorption and thickness swelling properties for all species tested. However, there was a reduction in strength properties as indicated by modulus of elasticity, modulus of rupture and toughness. The improvement in dimensional stability and reduction in strength properties were correlated with temperature but duration seemed to have little or no effect on physical or mechanical properties.
