【Abstract】 The vibration energy applied to the plain woven fiber composite material may have a certain attenuation owing t0 the characteristics in the composite structure.Due to the damping resistance of the interlaced two sets Of threads in both fiber yarns and viscoelastic properties in the polymer matrix,a part of the vibration energy acting on the composite has been lost.The calculation of the complicated structural loss factor for plain woven fiber composite can also be solved by elastic deformation energy principle.更多还原
