Özet:

 

Damping and vibration properties of polyethylene fiber  composite are investigated under varied temperature.  A damping  monitoring method is used to experimentally measure frequency response  and the frequency is obtained numerically using a finite element  program.  The natural frequencies of a system are a function of its  elastic properties, dimensions, and mass.  This concept is used to  calculate theoretical vibration modes of composites.  The damping  properties, in terms of the damping factor, are determined by the  half-power bandwidth technique.  The time responses measured experimentally are compared with the  numerically obtained ones.  Good agreement between the 2 methods shows  that numerical analysis can be used to determine the time response  curve of polyethylene fiber composite.  It is seen that polymer matrix  composites have temperature-dependent mechanical properties.  A  functional relationship between temperature and damping properties of  polyethylene fiber composite under varied temperature is obtained.
