Finishing characteristics of heat treated and compressed Rubberwood

The finishing characteristics of heat-treated and compressed Rubberwood were studied. It was found that heat-treated samples had significantly lower finish adhesion strength compared to the conventionally kiln-dried Rubberwood samples, which were used as control specimens. Further, compression of the specimens had also reduced its surface roughness, with an adverse effect on the finish adhesion strength. Inevitably, the use of heat treated and compressed wood in furniture may be suitable for applications, where lower finish adhesion strength could be tolerated at the expense of better finish film quality and process economics, especially in the manufacture of outdoor wooden furniture.     

Influence of the stiffness of corner joint on case furniture deflection

The stiffness of corner joints affects the strength of case furniture. The stiffness of corner joint was varied by changing the dowel quantity of case corner joints in this study. At first, the stiffness of corner joint parts was studied by experiments. then the Finite Element Method (FEM) was used to analyse and calculate the deflections of case furniture based on the jointing coefficienty R and the moduls of elasticityE ^* deduced from measurements on corner joint parts. Finally experiments to determine case furniture strength were carried out and the reliability of the calciulation of FEM was verified. The results of calculations and experiments showed that the deflection of case furniture could be reduced by 5–15 percent by increasing the dowel quanlity of corner joint from two dowels to four dowels or from four dowels to eight dowels. The defelection of case furniture containing shelves could be reduced by increasing the stiffness or corner joints.     

Festigkeitsuntersuchungen an Flächeneckverbindungen im Korpusmöbelbau

Corner-joints of two different particleboards, as they are used in the manufacture of case-type furniture, were prepared in 13 variations, fixed and detachable. These corner-jointed test specimens were subjected to various load tests to determine the failure under bending, as well as their angular stiffness. It became evident that the strength of the joints is influenced by the type of joint and by the particle-board quality. Especially in the case of mitre-jointing, the strength also depends on the loading method. The knowledge of these strength data ist necessary for predeterming the suitability of furniture desings, as well as for establishing standards for furniture testing.     

Load-bearing characteristics of heat-treated rubberwood furniture components and joints

The load bearing characteristics of heat-treated rubberwood furniture components and joints were studied. It was found that heat-treated samples had significantly lower fatigue strength compared to the conventionally kiln-dried rubberwood samples, which were used as control specimens. Inevitably, the recommended allowable design stresses for heat-treated rubberwood furniture components and joints could be set at 40 and 25 % of the respective bending strengths, in order to ensure its compliance with furniture performance standards. These figures are much lower than the allowable design stresses for conventionally kiln dried components, reflecting the need for a lower safety margin when working with heat-treated materials.
