Tema(s): Recursos en línea: Resumen: The effect of density on physical and mechanical properties of phenolic-impregnated cold-pressing reconstituted small-sized bamboo fibrous sheet composite was evaluated. The results indicated that with the density increased from 0.85g/cm 3 to 1.20 g/cm 3: water absorption decreased, thickness swelling increased first and then decreased; the value of modulus of rupture(MOR)increased from 120MPa to 230MPa, R 2 was 0.885; the value of modulus elasticity(MOE)increased from 1.8×10 4MPa to 2.8×10 4MPa, R 2 was 0.978; the shearing strength (perpendicular loading)increased from 6.5MPa to 18MPa, R 2 was 0.978;the shearing strength( parallel loading)increased from 6.3MPa to 26MPa, R 2 was 0.973;the compression parallel to grain values increased from 80MPa to 120MPa.
