摘　　要：对Ｆ４碳纤维复合管材制作的非标准试样，根据梁理论，在计入尺寸效应后动态测试了材料的弹性模量Ｅ和泊松比μ。在自制的加载装置上所进行的静态轴向拉伸和静态弯曲试验中测得的Ｅ和μ值和本文提出的动态法测试的结果极为一致，说明了动态法测试具有简便、快速、正确和重复性好等优点。依据板理论测试的剪切模量Ｇ的结果基本上满足Ｇ＝Ｅ／２（１＋μ）的关系，故可将这种Ｆ４碳纤维管材视为各向同性材料。Based on beam theory,the modulus of elasticity E and Poisson ratio μ of irregular test specimens made by F 4 carbon fibre composite pipe were measured by dynamic measurement regarding dimension effect. The values of E and μ measured in the axial tension and bending test of static measurement on the special loading equipment were consistent with the results measured by dynamic method.It shows that dynamic measurement is of simple,quick,correct and good repetition.The values of the shear modulus G are nearly accorded with the relation G=E/2(1+μ),so that F 4 carbon fibre pipe meterial in measuring can regarded as isotropy meterial.
