Abstract

This study investigated the effects of coupling agent content, wood fiber content and wood fiber type on the mechanical properties of wood fiber-reinforced polymer composites (WPC). This study adopted a response surface strategy of a 20 run optimal design for these three factors. The WPC modulus of elasticity was mainly influenced by wood fiber type and wood fiber content, and tensile stress at break depended on wood fiber type, wood fiber content and coupling agent content, whereas strain at break was significantly affected by wood fiber content and coupling agent content, but not significantly influenced by wood fiber type.

Zusammenfassung

In dieser Studie wird der Einfluss des Haftmittelgehalts, des Holzfasergehalts und der Holzfaserart auf die mechanischen Eigenschaften von Holz-Kunststoff-Verbundwerkstoffen (WPC) untersucht. Die Wirkung dieser drei Faktoren wurde mittels einer Response-Surface-Methode mit 20 Wiederholungen untersucht. Holzfaserart und Holzfasergehalt hatten einen wesentlichen Einfluss auf den E-Modul von WPCs. Die Zugfestigkeit hing von der Holzfaserart, dem Holzfasergehalt und vom Haftmittelgehalt ab. Die Bruchdehnung wurde im Wesentlichen vom Holzfaser- und Haftmittelgehalt beeinflusst, jedoch nicht von der Holzfaserart.
