Vibration characteristics of glass fabric/epoxy composites with different woven structures

We study the effects of woven structures on the vibration properties of the composites. Five typical weaving sets including the ordinary plain weaved and the warp interlocked were adopted in fabric processing. The composites plates with adequate thickness were prepared by epoxy resin curing, and their fiber volume fractions were examined. Dynamic mechanical analyzer and vibration test technique were used to reveal the dynamical behaviors of specimens in different frequencies of vibration. The result showed that the woven structure have a strong effect on the fiber volume fraction, resin-rich area, and the warp architectures of the composites, which determine the performances of the composites in vibration.
