Based on the designable mechanical characteristics of composite structure, a secondary vulcanization method of viscoelastic material is developed to manufacture the experimental specimens of embedded and co-cured composite damping structure (ECCDS). The mid-temperature co-cured process of the composite material embedding viscoelastic damping membrane is explored according to the glass fabric/epoxy composite cure cycle. By using a standing wave tube method, sound insulation performance of the composite damping structure is tested and compared with the composite laminates without the damping layer. The conclusion indicates that ECCDS has a very strong potential to insulate sound.

AbstractThe electrospray deposition method was used to deposit carbon nanotubes (CNT) onto the surfaces of woven carbon fiber (CF) to produce woven hybrid carbon fiber–carbon nanotubes (CF–CNT). Extreme high-resolution field emission scanning electron microscopy (XHR-FESEM), X-ray diffraction (XRD), Raman spectroscopy and Fourier transform infrared spectroscopy (FT-IR) were used to analyze the woven hybrid CF–CNT. The results demonstrated that CNT was successfully and homogenously distributed on the woven CF surface. Woven hybrid CF–CNT epoxy composite laminates were then prepared and compared with woven CF epoxy composite laminates in terms of their flexural and dielectric properties. The results indicated that the flexural strength, flexural modulus and dielectric constant of the woven hybrid CF–CNT epoxy composite laminates were improved up to 19, 27 and 25%, respectively, compared with the woven CF epoxy composite laminates.
