Abstract

This research was planned to study the influence of reinforcement with metal and woven synthetic nets on the mechanical properties of medium density fiberboard (MDF). Sample boards were manufactured according to common practice. However, reinforcements were placed in the boards at one fourth of their thicknesses. Urea formaldehyde resin was used in the boards. However, some metal nets were embedded in an epoxy resin prior to board manufacture. Bending and tensile strengths were determined according to ASTM D 1037-99, impact load resistance according to ASTM D 256-04 and board’s creep according to ASTM D 6815-02.

Results revealed that bending properties (MOE and MOR), tensile strength and impact load resistance were significantly increased due to the reinforcement. Boards reinforced with thin metal nets showed the highest MOR as 105% increase; while the highest MOE and impact load resistance were determined in the boards reinforced by thick metal nets, which were embedded primarily in the epoxy resin as 112% and 79%, respectively. The highest tensile strength was also determined in boards reinforced by thick metal nets. Boards reinforced by woven synthetic nets showed lower strengths than those of the metal nets.

Zusammenfassung

In dieser Studie wird der Einfluss einer Verstärkung von mitteldichten Faserplatten (MDF) mit Metallnetzen bzw. mit gewebten Synthetiknetzen auf deren mechanische Eigenschaften untersucht. Die Probeplatten wurden praxisüblich hergestellt. Die Verstärkungen wurden in ein Viertel bzw. Dreiviertel der Plattendicke eingebracht. Die Platten wurden mit Harnstoff-Formaldehydharz verklebt. Einige Metallnetze waren vor der Plattenherstellung in Epoxydharz eingebettet worden. Die Biege- und Zugfestigkeiten wurden gemäß ASTM D 1037-99, die Schlagbiegefestigkeit gemäß ASTM D 256-04 und das Kriechverhalten der Platten gemäß ASTM D 6815-02 bestimmt.

Die Ergebnisse zeigten, dass die Biegeeigenschaften (MOE und MOR), die Zugfestigkeit und auch die Schlagbiegefestigkeit aufgrund der Verstärkung signifikant höher waren. Die mit dünnen Metallnetzen verstärkten Platten wiesen mit einer Zunahme von 105% die höchste Biegefestigkeit auf, während sich der höchste Biege-E-Modul, 112 %, und die höchste Schlagbiegefestigkeit, 79%, in Platten, die mit dicken, in Epoxydharz eingebetteten Metallnetzen verstärkt waren, ergab. Die mit dicken Metallnetzen verstärkten Platten wiesen auch die höchste Zugfestigkeit auf. Die mit gewebten Synthetiknetzen verstärkten Platten zeigten niedrigere Festigkeiten als die mit Metallnetzen verstärkten Platten.
