the creep/recovery behavior of wood flour-polypropylene was compared with medium density fiberboard (mdf) and particleboard. for this purpose, wood flour-polypropylene composites (with and without compatibilizer)were manufactured by using a laboratory twin-screw extruder. the mdf and particleboard panels were obtained from local producers. short term flexural creep tests at 30% of ultimate bend...

this study was aimed to investigate the bending moment and stress (inner and outer corners) in lshaped biscuit joint made of solid wood, particleboard and medium density fiberboard (mdf). for this purpose, l-shaped joints made of beech and fir, particleboard and mdf by biscuit size numbers of 0 (47×15×3.8 mm), 10 (53×19×3.8mm) and 20 (60×23×3.8mm). bending moment and stress carrying capacity of...

In this study wheat straw was taken from Ankara province. In order to produce dry process MDF, urea formaldehyde resin was used at the ratio of 8 %, 10 % and 12 %, 1 % ammonium chloride was used as hardening agent on the basis of dry fiber weight. On the other hand, 5, 6 and 7 min. pressing times were applied. Alcohol benzene, cold water, hot water and 1 % NaOH solubility of wheat straw were 5....

This paper discusses selected properties of particleboard, hardboard, medium-densi­ ty fiberboard (MDF), and plywood related to their use in furniture and cabinet manu­ facture. Properties covered are screw-hold­ ing, internal bond, density profile, and edge appearance. Studies of direct screw with­ drawal of panel products indicate that re­ sistance to withdrawal from the edge is 75 to 80 perc...

This study was aimed to study the probability about the production of fiberboard made of durian rind through latex with phenolic resin as binding agent. The durian rind underwent the boiling process with NaOH [7], [8] and then the fiber from durian rind was formed into fiberboard through heat press. This means that durian rind could be used as replacement for plywood in plywood industry by usin...

The effect of dielectric barrier discharge (DBD) plasma treatment was studied on the surface characteristics and coating performance transparent epoxy resin particleboard (PB) medium-density fiberboard (MDF). performed at three energies (10, 15, 20 kW) distances from nozzle 20, 30 mm). Analyzing samples by Fourier transform infrared (FTIR) spectroscopy X-ray photoelectron (XPS) indicated change...

The objective of this study was to develop predictive expressions for estimating the withdrawal force capacity various size beech (Fagus orientalis) dowels from medium density fiberboard (MDF) and particleboard (PB). Furthermore, effects base material type, dowel diameter, penetration adhesive type on were investigated. Polyurethane (PU), polyvinyl acetate based D2, (PVA) adhesives utilized glu...

The potential use of nanoclay was examined to modify fluid transfer properties of medium density fiberboard (MDF). For this, Na+ montmorillonite (Na+MMT) nanoclay was added to urea formaldehyde resin to produce MDF. Then, the air permeability and mass diffusivity of MDF were evaluated. Scanning electron microscope (SEM) images and X-ray diffraction (XRD) confirmed a dispersion and exfoliation o...
