The influence of lightweight glass fiber reinforced thermoplastic composite(GMT)’s density and cantilever length on its damping ratio,frequency and dynamic elastic modulus through the free vibration of cantilever beams based on LabVIEW were studied. The experimental results show that the damping ratio and frequency of GMT increase with the decrease of GMT’s density and cantilever length. While the dynamic elastic modulus of GMT decrease with the decrease of GMT’s density and cantilever length.
