Five typical weaving sets including the ordinary plain weaved and the warp interlocked were adopted in fabric processing. The composites plates with the same thickness were prepared by epoxy resin curing, and their fibre volume fractions were examined. Dynamic Mechanical Analyzer (DMA) and vibration test technique were used to reveal the dynamical behaviours of specimens in different frequencies of vibration. The storage modulus, the loss tangent, the natural frequency and damping ratio<span style="mso-spacerun: yes;"> </span>were obtained. The result showed that the woven structure have a strong effect on the fibre volume fraction, resin-rich area and the warp architectures of the composites, which determines the performances of the composites in vibration.</span></span></p><p class="MsoNormal" style="text-justify: inter-ideograph; margin: 0cm 0cm 0pt; layout-grid-mode: char; text-align: justify; mso-layout-grid-align: none;"><span style="font-size: 9pt; mso-fareast-language: ZH-CN; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US;" lang="EN-US"><span style="font-family: Times New Roman;"><strong>Defence Science Journal, 2011, 61(5), pp.499-504</strong><strong><strong>, DOI:http://dx.doi.org/10.14429/dsj.61.296</strong></strong><br /></span></span></p>
