通过对不同厚度单板采用不涂胶、涂胶、压力浸胶处理，研究单板热压后的力学性能与密度 之间关系，以及单板在不同工艺条件下的纵横向力学性能。基于纤维增强复合材料的混合模型和层 合板刚度理论，构建单板涂胶和压力浸胶热压后的弹性模量物理模型和数学模型。结果表明：(1)随 着单板中胶黏剂固化和单板被压密实，单板的横向弹性模量可提高3倍。(2)随着密度的增加，单板 涂胶和压力浸胶热压后的纵向弹性模量的增加幅度不及无胶单板热压后的增加幅度。(3)涂胶单板的 横向弹性模量模型在模拟实际情况时要乘系数k，此次实验k为0.76较为合适。(4)将加压浸胶单板中 的胶层分为10层、单板分为11层能较好地模拟加压浸胶单板的弹性模量，纵向弹性模量模拟值较实 测值小5.8 %，横向弹性模量模拟值较实测值小1.7 %。

With no resin, spreading resin and impregnating resin under pressure, the relation between the veneer’s mechanical properties of length and breadth after hot pressing and the density were researched in a systematic way. Base on mixture mode of fiberreinforced composites and stiffness theory of laminate respectively, formulate the MOE model of physics and math of veneers which were treated with heat, pressure and resin. The result shows: (1)The veneer treated with heat, pressure and resin can get 3 times MOE on perpendicular diction than the veneer without treated. (2)The parallel MOE of veneer spreaded and impregnated resin under pressure will be increased with the density, and their increasing speed is lower than that of the compressed veneer. (3) After multiplying a coefficient k, here k=0.76, the perpendicular MOE model of the resin spreading veneer is close to the test value. (4)According to the theory of layer panel, the veneer with resin impregnated under pressure was divided 21 layers altogether with 11 thin veneer’s layers and 10 thin resin layers, and the model is close to the test value with 5.8 % deviation in parallel and 1.7 % deviation in perpendicular.
