摘　　要：以杨木单板为基材,金属铝箔为增强功能材料,聚醋酸乙烯酯乳液改性酚醛树脂为胶黏剂,热压制备多层单板铝箔复合功能人造板材,探讨金属铝箔在板材内部不同位置对多层单板铝箔复合功能人造板性能的影响。结果表明,金属铝箔的位置由板材上下两表面向芯层变化时,杨木单板与金属铝箔之间的胶合强度逐步提高,但板材的静曲强度、弹性模量逐渐降低,耐水性能减弱,金属铝箔在板材中的位置对复合功能板的性能有显著影响。研究结果为木基金属复合多层功能板材的设计与制备提供了理论依据和技术支持。In this paper,multi-layer plywoods with different structures made with poplar veneers and functional aluminum foils were prepared by hot-press using phenol formaldehyde resin modified by polyvinyl acetate emulsion as the adhesive.The effects of different positions of aluminum foils on the plywood performance were studied and discussed.The results showed that the bonding strength between poplar veneers and aluminum foils increased when the position of aluminum foil changes from the surfaces to the core layer,but the modulus of rupture and modulus of elasticity elastic of plywood decreased gradually.Meanwhile,the water resistance weakened.Panel structure had a significant impact on the performance of plywood.This research provides theoretical basis and technical support for the design and application of wood based metal multi-layer functional composites.
