Title

EFFECT OF UTILIZATION OF REED IN THE SURFACE LAYER OF 3-LAYER PARTICLEBOARD ON MOR, MOE AND BENDING FAILURE MODES

Pages

  49-57

Abstract

 The aim was to investigate the use of REED, as a substitute for wood, in laboratory made 3-layer PARTICLEBOARD in order to supplement the supply of raw material for the Iranian PARTICLEBOARD industries. The ratio of the mixture of REED and wood particles, in the surface and middle layers were 20:80, 30:70, 40:60, respectively. Press temperatures were chosen at two levels of 165 and 185oC. Three levels of urea formaldehyde resin were selected for the surface layers, namely: 8, 10 and 12 percent. Control samples were also made from wood particles only, under industrial production conditions. Then, the MOE, MOR of the boards were measured. FAILURE MODES were investigated based on the topography and the “clearness level” of the fracture zone. In general, the results show that REED has a positive effect on the mechanical properties of boards because of the higher slenderness ratio of REED particles which promote better adhesion and densification. In this research, the treatment with 40% REED, 12% resin in the surface layers and a 185°C press temperature has resulted in an optimum REED board product.
