摘　　要：采用酚醛树脂胶黏剂,以竹条含水率、涂胶量为试验因子进行竹集成材的高频热压胶合试验,并对其物理力学性能进行检验。结果表明,竹集成材高频热压胶合技术是可行的。在本试验范围内,竹集成材的密度和胶合性能随涂胶量的增加而提高。通过分析试验数据,得出较优的高频热压胶合工艺条件为:涂胶量300 g/m2,竹条含水率12%,高频热压时间10 min。Bamboo strips were bonded by phenol formaldehyde resin by using high frequency hot press to prepare glued laminated bamboo （GLB）. The influences of bamboo moisture content and adhesive spread on physical and mechanical properties of GLB were investigated. The results showed that higher moisture content and spread improved the performances of GLB. The optimal pressing was achieved when the spread, moisture content and pressing time were 300 g/m2 , 12% and 6min, respectively.
