摘　　要：Novel woodceramics were successfully fabricated by enzymatic hydrolysis lignin （EHL） modified phenol-formaldehyde resin and woodpowders. The microstructure of woodceramics was investigated by FT-IR, X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The effects of EHL-modified PF resin on the properties of woodceramics, such as the weight loss ratio, volume shrinkage ratio, open porosity, bending strength and compressive strength, were studied. The experimental results showed that EHL modified woodceramics had a uniform porous structure. EHL-modified PF resin played an important role in the properties of woodceramics. With the increase of EHL-modified PF resin content, the open porosity, weight loss ratio and volume shrinkage ratio of woodceramics increased, but the bending strength and compressive strength decreased.Novel woodceramics were successfully fabricated by enzymatic hydrolysis lignin （EHL） modified phenol-formaldehyde resin and woodpowders.
