Title

Urea-f ormaldehyde resin reinforced silk cocoon

Pages

  500-509

Abstract

 The aim of this research was to use a natural component, renewable and environmentally friendly material (Silk cocoon) as reinforcing component for urea formaldehyde resin in the plywood manufacturing and investigate its influence on physical and mechanical properties of plywood. For this purpose, Silk cocoon was used as filler and reinforcement at four levels of 0, 10, 20 and 30 percent (based on dry weight of urea formaldehyde resin). The physical and mechanical properties of samples including water absorption and thickness swelling after 2 and 24 hours immersion in water, bending strength parallel and perpendicular to the surface layer grain and shear strength were measured. The results show that increasing the content amount of Silk cocoon decreased water absorption and thickness swelling after 2 and 24 hours immersion in water and increased bending strength parallel and perpendicular to the surface layer grain and shear strength. So that, using 30 percent of Silk cocoon improved dimensional stability, bending strength and shear strength.
