摘　　要：为增强木质基面板的力学性能,采用在外侧单板内侧铺设平行或垂直于单板的定向碳纤维布的方法,以二苯甲烷二异氰酸酯为胶黏剂,在热压条件下制备7层碳纤维增强面板,研究增强后面板的弯曲、拉伸和剪切等力学性能。结果表明,碳纤维布平行铺设的胶合板面板胶合剪切强度是垂直铺设的1.3倍,抗拉强度是垂直铺设的2倍,静曲强度是垂直铺设的1.5倍。铺设碳纤维布的增强结构面板具有良好的比强度,力学性能得到较大提高,在生产应用中具有广阔应用前景。To enhance the mechanical properties of wood-based panels,a seven-layer carbon fiber-reinforced panel was prepared by laying oriented carbon fiber fabric parallel or vertical to the inner side of the outer veneer with diphenylmethane diisocyanate as adhesive under hot pressing conditions to study the mechanical properties of the reinforced panel in bending,tensile and shear.The results showed that the bonding shear strength of plywood panels with carbon fiber cloth laid in parallel was 1.3 times that of vertical lay-up,the tensile strength was twice that of vertical lay-up,and the static flexural strength was 1.5 times that of vertical lay-up.The reinforced structural panel with carbon fiber cloth laying has good specific strength and the mechanical properties are greatly improved,which has a broad application prospect in production applications.
