摘要
选用正交试验方案，初步讨论了１１个结构和工艺因子与杨木复合板静曲强度、内结合强度、吸水厚度膨胀率、握钉力等之间的关系，结果表明：在工艺因子水平搭配合理的情况下，板子密度、表层刨花厚度、表芯层刨花比、芯层普通刨花与碎单板比是影响强度指标的主要因子，表层刨花施胶量、芯层刨花施胶量、热压温度、热压时间对板子的力学强度也有较大影响，其它因子作用较小。
Abstract By means of the orthogonal design method,a prelimilary study was made to investigate the relation-ships between 11 structural and technical factors and strength properties of poplar composite board. The test resultsshow that under the proper arrangment of the technical conditions,the average density,the thickness of surface lay-er particle,the percent of particle in surface and core layers and the percent of particle and veneer shaving in corelayer are the most important factors affecting the strength properties of poplar composite board.Resin content insurface and core layers,hot pressing temperature and time also affect the strength properties.Other factors are ofminor effect on them.
