Physical and mechanical properties of composite boards from the mixture of palm sugar fiber and cassava bagasse using mycelium of Ganoderma lucidum as a biological adhesive

Abstract

Composite board made from palm sugar fiber (PSF) and cassava bagasse fiber (CB) bonded with biological adhesive from mycelium of Ganoderma lucidum was prepared. The composite boards were divided by varying the composition ratios of the PSF and CB (A = 65: 35; B = 50: 50; and C = 35: 65% w/w of composite board weight). The physical and mechanical properties of PSF/CB composite boards were carried out. The results showed that the moisture content, density, thickness swelling, and water absorption were 7.93 - 8.80%; 0.32 - 0.61/cm3; 13.5 - 18.00 %; and 64.22 - 116.96%, respectively. This study also revealed that the internal bond, modulus of rupture (MOR) and modulus of elasticity (MOE) were 0.03 - 0.76 MPa, 0.48 - 3.80 MPa, and 23.79 - 419.84 MPa, respectively. The Physical and mechanical properties of composite board fulfilled Japan Industrial Standard for particleboard. Hence, mycelium of Ganoderma lucidum could be used as a biological adhesive in composite board production.
