Tensile Strength of Composites from Hanji ( Korean paper ) Sludge Mixed with Wood Fiber or Particle

This research was carried out to investigate the Hanji sludge(black color)-wood fiber and wood particle composites applied by waste sludges arising from the making process of Hanji (Korean paper). In experimental design, four levels of the mixed ratio of Hanji sludge to wood fiber or wood particle(10:90, 20:80, 30:70 and 40:60), three kinds of the resin(PMDI, urea and phenol resin) and three kinds of the specific gravity(O.6, 0.75 and 0.9) were designed to determine the tensile strength of Hanji sludge-wood fiber and wood particle composites. From the results and discussion, it may be concluded as follows: In Hanji sludge-wood fiber and wood particle composites, tensile strengths showed decreasing tendency absolutely by increasing Hanji sludge additive, but clearly increased with the increase of specific gravity. In Hanji sludge-wood fiber composites, there were no differences between PMDI and. urea resin-bonded composites, but phenol resin-boned composites were inferior to others in tensile strengths. Hanji sludge-wood fiber composites were made possibly until the addition of 30% Hanji sludge. On the other hand, Hanji sludge-wood particle composites(SpGr =0.6) have very low tensile strength values. But they were made favorably until the addition of 20% Hanji sludge in Hanji sludge-wood particle composites(SpGr=O.9).
