为了研究木材陶瓷的断裂行为及其影响因素,以山毛榉薄木和液化木材为基材制备叠层结构木材陶瓷,分析了基本结构、烧结温度、液化木材用量和胶合压力等工艺因素对其断裂行为的影响。结果表明:叠层结构能够使断裂裂纹偏转,有利于改善木材陶瓷的断裂行为。当烧结温度、液化木材用量和胶合压力分别为1200℃、80%和7 MPa时,制备的木材陶瓷呈现出较完整的叠层结构,并可获得相对较好的断裂韧性,其值是无叠层结构的2~3倍。

In order to investigate the fracture behaviour and influence factors of woodceramics, laminated woodceramics was prepared from bench veneer and liquefied wood, and the effects of basic structure and interlaminated binding strength, sintering temperature, liquefied wood content and glueing pressure on the fracture behaviour of the woodceramics was analysed. The results show that the laminated structure can make the rupture crack deflection, which is of benefit to improve the fracture behaviour. As the sintering temperature, liquefied wood content and glueing pressure are 1200, 80% and 7 MPa, re...
