摘要
采用XRD、SEM等技术,对以杨木纤维/PF树脂为基材制备的木陶瓷进行了研究,结果表明:木陶瓷呈三维网状结构,保持了木材结构的部分特征,随着烧结温度的升高有可石墨化倾向;随着树脂含量的增加和烧结温度的升高,木陶瓷的抗压强度、弹性模量以及耐磨性能增强,表观密度和显气孔率升高,而体积电阻率迅速降低。
Development of wood-ceramic products made from poplar fiber impregnated with phenol-formaldehyde resin was investigated in this study. It was found that the three-dimensiona） structure of wood-ceramic samples was very similar to the one of a typical natural wood. The crystallization and the tendency of graphitization increased considerably with the raise of the sintering temperature. The results showed that the compressive strength, elastic modulus, and abrasion resistance of the wood ceramic samples improved dramatically when the resin contents and sintering temperature increased, especially for the sintering temperature between 500℃ and 800℃. The apparent density and porosity also increased when the resin content and sintering temperature increased, but the electrical resistance rapidly decreased.
