Effect of Density on Physical and Mechanical Properties of Reconstituted Small-Sized Bamboo Fibrous Sheet Composite
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/cm3 to 1.20 g/cm3: water absorption decreased, thickness swelling increased first and then decreased; the value of modulus of rupture(MOR) increased from 120MPa to 230MPa, R2 was 0.885; the value of modulus elasticity(MOE) increased from 1.8×104MPa to 2.8×104MPa, R2 was 0.978; the shearing strength (perpendicular loading) increased from 6.5MPa to 18MPa, R2 was 0.978;the shearing strength( parallel loading) increased from 6.3MPa to 26MPa, R2 was 0.973;the compression parallel to grain values increased from 80MPa to 120MPa.
