The Study On The Fungal Decay Resistance Of Wood-plastic Composites

An emerging new composites material is known as Wood Plastic Composite. This paper focuses on the properties of white-rot decay-resistance, Brown-rot fungi-resistance and soft-rot fungi-resistance of four kinds of wood plastic composite as well as the Termites-resistance of PE/plastic composite.The results are as follows:1.Four kinds of wood-plastic composites'weight lose very little after white-rot fungi fungi, brown fungi and soft fungi experiment. The decay resistance of four wood-plastic composites is much better than poplar. The weight lose of four kinds of WPC are less than 6% after treatment of white-rot fungi, brown-rot fungi and soft-rot fungi. The weight loss of bamboo inside-WPC is the most one, while others three's are less than 4% .The decay resistance of four kinds of WPC are better compared to poplar.2.The color of four kinds of WPC and poplar after white-rot fungi, brown-rot fungi and soft-rot fungi test has changed greatly, especially poplar.3. WPC's loss rate of MOE range from 50% to 40.0% after the treatment of white-rot fungi, while its loss rate of MOE range from 45.2%-39.5% after the treatment of brown-rot fungi. However, there is a few decline of bending modulus after the treatment of soft-rot fungi. The loss rates of MOE are all less than 15%.4. There is no obvious imprint on the surface of PE/plastic composite while lots of gully in the surface of poplar.
